Niedokrwienie jelit
Leczenie
Niedokrwienie jelitowe to stan krytyczny charakteryzujący się zaburzeniem perfuzji jelitowej prowadzącym do uszkodzenia tkanki i wysokiego ryzyka powikłań zagrażających życiu. W terapii kluczowe jest szybkie przywrócenie przepływu krwi, usunięcie martwicy oraz zapobieganie sepsie. Postępowanie wstępne obejmuje agresywną resuscytację płynową, korekcję zaburzeń elektrolitowych, odbarczenie żołądka, antybiotykoterapię o szerokim spektrum oraz unikanie leków wazokonstrykcyjnych. Leczenie farmakologiczne różnicuje się w zależności od etiologii: heparyna niefrakcjonowana (3-6 miesięcy, a w trombofilii dożywotnio) w zakrzepicy, trombolityki w zatorowym niedokrwieniu tętniczym, papaweryna (60 mg bolus, 30-60 mg/godz. wlew ciągły) w nieokluzyjnym niedokrwieniu krezkowym (NOMI). Wskazane jest monitorowanie na OIT oraz stosowanie leczenia przeciwbólowego i przeciwzakrzepowego. W ostatnich dekadach rozwój technik endowaskularnych (angioplastyka balonowa, stentowanie, tromboliza celowana, trombektomia mechaniczna) stanowi mniej inwazyjną alternatywę dla chirurgii otwartej, szczególnie w ostrym niedokrwieniu tętniczym.
Leczenie niedokrwienia jelit
Niedokrwienie jelit (niedokrwienie jelitowe) to stan, w którym dochodzi do zaburzenia przepływu krwi do jelit, co prowadzi do uszkodzenia tkanki jelitowej i potencjalnie zagrażających życiu powikłań. Wczesne rozpoznanie i szybkie wdrożenie leczenia są kluczowe dla poprawy rokowania pacjentów. Celem terapii jest przywrócenie prawidłowego przepływu krwi do przewodu pokarmowego, usunięcie martwiczych tkanek (jeśli występują) oraz zapobieganie powikłaniom. Wybór metody leczenia zależy od typu, przyczyny i nasilenia niedokrwienia jelitowego.123
Postępowanie wstępne
Wstępne postępowanie w niedokrwieniu jelitowym obejmuje szereg działań mających na celu stabilizację stanu pacjenta i przygotowanie do dalszego leczenia:45
- Resuscytacja płynowa – agresywne podawanie płynów dożylnych w celu poprawy perfuzji trzewnej
- Monitorowanie i korekcja zaburzeń elektrolitowych
- Odbarczenie żołądka przy pomocy sondy nosowo-żołądkowej
- Wdrożenie antybiotykoterapii o szerokim spektrum działania (pokrywającej florę jelitową) w celu zapobiegania lub leczenia sepsy
- Unikanie leków wazokonstrykcyjnych, które mogą pogłębić niedokrwienie
- Zaprzestanie odżywiania doustnego (NPO – nic doustnie)
Pacjenci z ostrym niedokrwieniem jelit zwykle wymagają monitorowania na oddziale intensywnej terapii, gdzie można precyzyjnie kontrolować parametry hemodynamiczne i szybko reagować na zmiany stanu klinicznego.8
Leczenie farmakologiczne
W zależności od typu niedokrwienia jelitowego, stosowane są różne grupy leków:9
- Antykoagulanty – heparyna niefrakcjonowana podawana dożylnie jest podstawowym lekiem w ostrym niedokrwieniu tętniczym oraz w zakrzepicy żył krezkowych. Stosowanie heparyny zapobiega narastaniu zakrzepu i jest zalecane przez 3-6 miesięcy. W przypadku współistniejącej trombofilii, leczenie przeciwzakrzepowe może być konieczne przez całe życie.1011
- Leki trombolityczne – stosowane w wybranych przypadkach zatorowego niedokrwienia tętniczego, podawane bezpośrednio do tętnicy krezkowej podczas angiografii. Wskazane są u pacjentów z dystalnym zatorem krezkowym lub niekompletną aspiracyjną embolektomią.1213
- Wazodylatatory – papaweryna podawana bezpośrednio do tętnicy krezkowej poprzez cewnik angiograficzny jest stosowana w nieokluzyjnym niedokrwieniu krezkowym oraz w innych formach tętniczego niedokrwienia. Mechanizm działania polega na rozluźnieniu skurczu naczyń.1415
- Antybiotyki – szerokospektralna antybiotykoterapia jest zalecana w celu zapobiegania i leczenia sepsy spowodowanej przerwaniem bariery śluzówkowej jelita, martwicą lub perforacją jelita.1617
- Leki przeciwbólowe – stosowane do uśmierzenia bólu spowodowanego niedokrwieniem jelita.18
Warto zaznaczyć, że papaweryną nie powinna być podawana jednocześnie z heparyną ze względu na zwiększone ryzyko wytrącania się papaweryną.19
Leczenie interwencyjne
Metody wewnątrznaczyniowe
W ostatnich dwóch dekadach nastąpił znaczny rozwój technik endowaskularnych, które stały się ważną alternatywą dla tradycyjnej chirurgii otwartej w leczeniu niedokrwienia jelitowego. Metody te charakteryzują się mniejszą inwazyjnością i krótszym czasem rekonwalescencji.2021
- Angioplastyka balonowa – zabieg polegający na rozszerzeniu zwężonej tętnicy przy pomocy balonu. Wykonywany zwykle podczas angiografii diagnostycznej. Balon umieszczony na końcu cewnika jest wprowadzany do zwężonego miejsca i rozprężany, co powoduje poszerzenie naczynia i poprawę przepływu krwi.2223
- Implantacja stentu – często wykonywana po angioplastyce balonowej. Stent (metalowa siateczka) jest umieszczany w miejscu zwężenia, aby utrzymać drożność tętnicy. Stosowanie stentów pozwala na długotrwałe utrzymanie drożności naczynia.2425
- Tromboliza celowana – polega na miejscowym podaniu leków trombolitycznych bezpośrednio do zakrzepu przez cewnik. Metoda ta jest wskazana u pacjentów z zatorowym niedokrwieniem krezkowym w czasie do 8 godzin od początku objawów.2627
- Trombektomia mechaniczna – usunięcie zakrzepu lub zatoru przy pomocy specjalnych cewników z mechanizmem ssącym lub pętlą do wydobycia materiału zatorowego.2829
Badania wykazały, że u pacjentów z ostrą niedrożnością tętniczą krezkową interwencje wewnątrznaczyniowe mogą być równie skuteczne jak tradycyjne leczenie chirurgiczne, zwłaszcza gdy są wykonywane we wczesnym etapie choroby.3031
Leczenie chirurgiczne
Leczenie chirurgiczne jest niezbędne w przypadkach zaawansowanego niedokrwienia jelitowego, gdy występują objawy otrzewnowe, perforacja jelita lub martwica jelita. W zależności od przyczyny i stopnia zaawansowania stosuje się różne techniki:3233
- Embolektomia – zabieg polegający na usunięciu zatoru z tętnicy krezkowej. Jest to metoda z wyboru w przypadku ostrego niedokrwienia zatorowego.3435
- Trombendarteriektomia – usunięcie blaszki miażdżycowej i zakrzepu z wnętrza tętnicy krezkowej. Zabieg wykonywany głównie w przewlekłym niedokrwieniu jelit.3637
- Bypass naczyniowy – polega na utworzeniu pomostu omijającego niedrożny odcinek tętnicy krezkowej. Najczęściej wykonuje się bypass od aorty do tętnicy krezkowej górnej. Jest to skuteczna metoda, nawet w przypadku niedrożności wielu naczyń.3839
- Resekcja jelita – usunięcie martwiczego odcinka jelita jest konieczne w przypadku nieodwracalnego uszkodzenia ściany jelita. Po resekcji można wykonać zespolenie końców jelita lub, w niektórych przypadkach, wyłonienie stomii.4041
- Laparotomia zwiadowcza – wykonywana w celu oceny stopnia uszkodzenia jelita i podjęcia decyzji o dalszym postępowaniu.4243
- Operacja „second-look” – ponowna laparotomia wykonywana 24-48 godzin po pierwszym zabiegu w celu oceny żywotności pozostawionego jelita. Jest to istotny element postępowania w ostrym niedokrwieniu jelit, pozwalający na uniknięcie zbyt rozległej resekcji podczas pierwszego zabiegu.4445
W przypadkach masywnej martwicy jelita konieczna jest staranna ocena współistniejących chorób pacjenta oraz jego życzeń, aby określić, czy dalsza eskalacja leczenia jest uzasadniona.46
Leczenie w zależności od typu niedokrwienia
Ostre niedokrwienie tętnicze
Ostre niedokrwienie tętnicze jelit jest stanem zagrożenia życia wymagającym natychmiastowej interwencji. Postępowanie zależy od mechanizmu niedokrwienia (zator vs. zakrzep) oraz stanu klinicznego pacjenta:4748
- Niedokrwienie zatorowe – najczęściej leczone chirurgicznie poprzez embolektomię. W wybranych przypadkach można zastosować trombolizę celowaną. Po zabiegu konieczne jest długotrwałe leczenie przeciwzakrzepowe.4950
- Niedokrwienie zakrzepowe – leczenie obejmuje rewaskularyzację chirurgiczną lub endowaskularną (angioplastykę ze stentowaniem). Wybór metody zależy od lokalizacji zakrzepu, stanu klinicznego pacjenta oraz doświadczenia ośrodka.5152
Jeśli podczas laparotomii stwierdza się martwicę jelita, konieczna jest resekcja nieodwracalnie uszkodzonych odcinków. W przypadku wątpliwej żywotności fragmentów jelita, zaleca się wykonanie operacji „second-look” w ciągu 24-48 godzin.5354
Zakrzepica żylna krezkowa
Leczenie zakrzepicy żył krezkowych różni się od postępowania w niedokrwieniu tętniczym:5556
- Antykoagulacja – podstawą leczenia jest podanie heparyny niefrakcjonowanej, a następnie warfaryny przez okres co najmniej 3-6 miesięcy. W przypadku nawracającej zakrzepicy lub trombofilii, leczenie przeciwzakrzepowe może być konieczne przez całe życie.5758
- Tromboliza celowana – w wybranych przypadkach stosuje się leki trombolityczne podawane bezpośrednio do zakrzepniętej żyły poprzez dostęp przezwątrobowy.59
- Trombektomia mechaniczna – zabieg usunięcia zakrzepu z wykorzystaniem specjalnych cewników.60
- Leczenie chirurgiczne – wskazane w przypadku utrzymujących się objawów pomimo leczenia zachowawczego lub objawów otrzewnowych sugerujących martwicę jelita.61
W przypadku łagodnych objawów i braku cech upośledzenia perfuzji jelita w badaniu CT, można zastosować heparynę drobnocząsteczkową, a następnie doustne leki przeciwzakrzepowe.62
Nieokluzyjne niedokrwienie krezkowe
Nieokluzyjne niedokrwienie krezkowe (NOMI – Non-Occlusive Mesenteric Ischemia) jest spowodowane skurczem naczyń krezkowych bez ich mechanicznej niedrożności. Leczenie różni się od postępowania w innych typach niedokrwienia jelitowego:6364
- Eliminacja czynników wywołujących – odstawienie leków wazokonstrykcyjnych, leczenie niewydolności serca, sepsy i innych stanów prowadzących do hipoperfuzji trzewnej.6566
- Stabilizacja hemodynamiczna – resuscytacja płynowa, korekcja zaburzeń elektrolitowych, przetoczenia krwi jeśli konieczne.67
- Leki wazodylatacyjne – papaweryną podawana przez cewnik dotętniczy w dawce 60 mg w bolusie, a następnie w ciągłym wlewie 30-60 mg/godz. z kontrolą angiograficzną co 24 godziny.6869
- Laparotomia – wskazana przy podejrzeniu martwicy jelita.70
NOMI charakteryzuje się wysoką śmiertelnością, ale dzięki stosowaniu dotętniczych wazodylatatorów udało się zmniejszyć śmiertelność z 70% w latach 80. do 50-55% w ostatniej dekadzie.71
Niedokrwienie okrężnicy
Niedokrwienie okrężnicy (ischemic colitis) jest najczęstszą formą niedokrwienia jelit. W większości przypadków ma przebieg łagodny i ustępuje samoistnie. Leczenie zależy od nasilenia objawów:7273
- Leczenie zachowawcze – w łagodnych przypadkach:
- Płyny dożylne w celu zapobiegania odwodnieniu
- Antybiotyki o szerokim spektrum działania
- Odstawienie leków potencjalnie pogarszających perfuzję okrężnicy
- Odpoczynek jelitowy – początkowo dieta zerowa, następnie płyny, a w końcu dieta lekkostrawna o niskiej zawartości błonnika
- Tlenoterapia w celu zwiększenia rzutu serca i przepływu krwi
- Odbarczenie żołądka przez sondę nosowo-żołądkową w przypadku niedrożności porażennej
- Leczenie zabiegowe – w ciężkich przypadkach:
- Zabiegi wewnątrznaczyniowe – usunięcie zakrzepu, angioplastyka, stentowanie
- Kolektomia – usunięcie martwiczego odcinka okrężnicy, czasem z wyłonieniem stomii
Około 20% pacjentów z niedokrwieniem okrężnicy wymaga interwencji chirurgicznej. Wskazaniami do operacji są: objawy otrzewnowe, gorączka, niekontrolowane krwawienie, niedrożność porażenna lub progresja zmian w kontrolnych badaniach endoskopowych.7778
Przewlekłe niedokrwienie krezkowe
Przewlekłe niedokrwienie krezkowe (CMI – Chronic Mesenteric Ischemia) rozwija się stopniowo w wyniku postępującego zwężenia tętnic krezkowych, najczęściej na tle miażdżycy. Leczenie ma na celu złagodzenie objawów i zapobieganie progresji do ostrego niedokrwienia:7980
Leczenie zachowawcze w CMI
- Modyfikacja diety – częste, małe posiłki o niskiej zawartości tłuszczu, aby zmniejszyć zapotrzebowanie na przepływ krezkowy.8182
- Leki przeciwpłytkowe – aspiryna w celu zmniejszenia ryzyka zakrzepicy.8384
- Kontrola czynników ryzyka – zaprzestanie palenia, leczenie nadciśnienia tętniczego, cukrzycy i dyslipidemii.8586
Leczenie rewaskularyzacyjne w CMI
U pacjentów z objawowym przewlekłym niedokrwieniem krezkowym zaleca się rewaskularyzację. Towarzystwo Chirurgii Naczyniowej (SVS) rekomenduje leczenie endowaskularne jako pierwszą linię terapii u pacjentów z odpowiednimi zmianami:8788
- Leczenie endowaskularne:
- Angioplastyka i stentowanie tętnic krezkowych – obecnie preferowana metoda ze względu na mniejszą inwazyjność i krótszy czas rekonwalescencji. Eksperci zalecają stosowanie stentów zamiast samej angioplastyki w leczeniu miażdżycowego zwężenia tętnic krezkowych.
- Najczęściej rewaskularyzuje się tętnicę krezkową górną, gdyż ma to największe szanse na trwałą poprawę.
- Leczenie chirurgiczne:
- Endarterektomia krezkowa – usunięcie blaszki miażdżycowej z tętnicy krezkowej.
- Bypass naczyniowy – najczęściej od aorty do tętnicy krezkowej górnej. Zabieg skuteczny nawet przy niedrożności wielu naczyń.
Wybór metody leczenia zależy od stanu pacjenta, lokalizacji i charakteru zmian w naczyniach krezkowych oraz doświadczenia ośrodka. U pacjentów wysokiego ryzyka operacyjnego preferuje się metody endowaskularne.9293
Postępowanie po leczeniu
Po skutecznym leczeniu niedokrwienia jelitowego konieczne jest długotrwałe monitorowanie pacjenta oraz wdrożenie odpowiedniego postępowania:9495
Postępowanie pooperacyjne
- Monitorowanie na OIT – pacjenci po leczeniu ostrego niedokrwienia jelitowego wymagają ścisłego monitorowania na oddziale intensywnej terapii. Postępowanie ukierunkowane jest na poprawę perfuzji jelitowej i zapobieganie niewydolności wielonarządowej.96
- Leczenie przeciwzakrzepowe – pacjenci po rewaskularyzacji powinni otrzymywać leki przeciwzakrzepowe przez co najmniej 6 miesięcy, a w przypadku trombofilii – dożywotnio.9798
- Leki przeciwpłytkowe – aspiryna dożywotnio u wszystkich pacjentów po leczeniu rewaskularyzacyjnym, klopidogrel przez 1-3 miesiące po zabiegach endowaskularnych.99
- Monitorowanie drożności naczyń – regularne badania obrazowe w celu oceny drożności stentów lub pomostów naczyniowych.100101
Postępowanie żywieniowe
- Okres ostry – początkowo całkowite wstrzymanie żywienia doustnego, żywienie pozajelitowe w razie potrzeby.102103
- Okres rekonwalescencji – stopniowe wprowadzanie diety:
- Dieta płynna
- Dieta półpłynna
- Dieta lekkostrawna o niskiej zawartości błonnika
- Zalecenia długoterminowe – u pacjentów po epizodzie niedokrwienia okrężnicy lub z przewlekłym niedokrwieniem jelit:
- Częste, małe posiłki
- Dieta o niskiej zawartości tłuszczu
- Unikanie pokarmów powodujących wzdęcia i gazów
U pacjentów z niedożywieniem przed operacją może być konieczne żywienie pozajelitowe zarówno przed, jak i po zabiegu.106
Metody eksperymentalne i nowe kierunki leczenia
Badania nad nowymi metodami leczenia niedokrwienia jelitowego koncentrują się głównie na strategiach farmakologicznych mających na celu zmniejszenie uszkodzeń spowodowanych niedokrwieniem i reperfuzją:107108
- Inhibitory fosfodiesterazy typu 5 – mogą poprawiać mikrokrążenie jelitowe.109
- Pentoksyfilina – poprawia właściwości reologiczne krwi i zmniejsza sztywność erytrocytów.110
- Rebamipid – lek o właściwościach gastroprotekcyjnych i przeciwzapalnych.111
- Prostaglandyna E1 – wazodylatator poprawiający perfuzję trzewną.112
- Polidezoksyrybonukleotydy – wykazują działanie angiogenne i przeciwzapalne.113
- Terapia tlenem hiperbarycznym – może zmniejszać uszkodzenia związane z niedokrwieniem-reperfuzją poprzez redukcję stresu oksydacyjnego, kontrolę stanu zapalnego i stymulację angiogenezy. Badania wykazują korzystny wpływ na zmniejszenie ekspresji Gpx4, co sugeruje zmniejszenie zapotrzebowania na odpowiedź antyoksydacyjną dzięki redukcji reaktywnych form tlenu.114115
Hipoteza „podwójnego uderzenia” w uszkodzeniu niedokrwiennym zakłada, że szkody są spowodowane zarówno pierwotnym epizodem hipoksji, jak i następczym uszkodzeniem reperfuzyjnym po przywróceniu przepływu krwi. Nowe strategie terapeutyczne dążą do minimalizacji obu komponentów uszkodzenia.116117
Podsumowanie leczenia
Niedokrwienie jelitowe pozostaje poważnym stanem klinicznym, związanym z wysoką śmiertelnością i chorobowością. Kluczowe elementy skutecznego leczenia obejmują:118119
- Wczesne rozpoznanie i szybkie wdrożenie leczenia
- Wielodyscyplinarne podejście z udziałem chirurgów naczyniowych, chirurgów ogólnych, intensywistów i radiologów
- Indywidualizację leczenia w zależności od typu niedokrwienia, jego nasilenia i przyczyny
- Postępowanie ukierunkowane na przywrócenie przepływu krwi do jelit, usunięcie nieodwracalnie uszkodzonych tkanek i zapobieganie powikłaniom
- Długoterminowe monitorowanie i leczenie podtrzymujące
Pomimo rozwoju technik diagnostycznych i terapeutycznych, śmiertelność w ostrym niedokrwieniu jelit pozostaje wysoka (50-90%). Najlepsze wyniki osiąga się w ośrodkach dedykowanych, stosujących ustandaryzowane protokoły postępowania i dysponujących doświadczonym zespołem wielospecjalistycznym.120121

- #1 Intestinal ischemia – Diagnosis and treatment – Mayo Clinichttps://www.mayoclinic.org/diseases-conditions/intestinal-ischemia/diagnosis-treatment/drc-20373950
Treatment of intestinal ischemia involves restoring the blood supply to the digestive tract. Choices vary depending on the cause of the condition and how bad it is. […] For severe colon damage, you may need surgery to remove the dead tissue. You also may need surgery to bypass a blockage in one of your intestinal arteries. If you have angiography to diagnose the condition, it may be possible to widen a narrowed artery during the procedure. […] Angioplasty uses a balloon inflated at the end of a catheter to press in the fatty deposits. The balloon also stretches the artery, making a wider path for the blood to flow. […] Your healthcare professional may put a springlike metallic tube, called a stent, into your artery to help keep it open. Your health professional also can remove a blood clot or dissolve it with medicine.
- #2 Bowel Ischemia – StatPearls – NCBI Bookshelfhttps://www.ncbi.nlm.nih.gov/books/NBK554527/
Regardless of the etiology of intestinal ischemia, in patients suspected of intestinal infarction or perforation based on clinical, radiographic, or laboratory tests, exploratory laparotomy should not be delayed. […] Resection of the infarcted intestine is strongly indicated. […] The treatment of NOMI or colonic ischemia focuses on removing insulting factors (vasoconstrictive medications), hemodynamic support and monitoring, treating the underlying cause (sepsis, heart failure), and the administration of intra-arterial vasodilation medications. […] Severe ischemia requires prompt surgical referral and intensive care unit monitoring.
- #3 Small Bowel Ischemia – American College of Gastroenterologyhttps://gi.org/topics/small-bowel-ischemia/
Small bowel ischemia requires prompt medical care to avoid damage to intestinal tissue that can lead to death. […] The goals of treatment are to restore blood supply to the intestines and maintain proper function in the digestive tract. Treatment options for intestinal ischemia vary depending on the cause of the condition and the severity of damage in the intestines. […] If you have small bowel ischemia but no damage to intestinal tissue, medications may be enough to manage the condition. Your doctor may recommend one or more medications, such as clot-busting medications to break up blood clots, blood thinners (anticoagulant medications) to prevent blood clots, and antibiotics to treat or prevent infections. […] Angioplasty is a minimally invasive catheter procedure that doctors use to open narrowed blood vessels. […] Depending on your specific case, surgery might be the best treatment option. Typical surgical procedures include laparoscopy and laparotomy.
- #4 Bowel Ischemia – StatPearls – NCBI Bookshelfhttps://www.ncbi.nlm.nih.gov/books/NBK554527/
Bowel ischemia can classify as small intestine ischemia, which is commonly known as mesenteric ischemia and large intestine ischemia, which generally referred to as colonic ischemia. […] This activity describes the etiology, evaluation, and management of bowel ischemia and highlights the role of the interprofessional team in improving care for patients with this condition. […] Summarize the treatment options of bowel ischemia. […] Based on acute mesenteric ischemia (AMI) subtypes, different medication treatments have been suggested. Papaverine, through the angiographic catheter with the mechanism of relaxation of vessels vasospasm, can be used for all arterial forms of AMI and nonocclusive mesenteric ischemia. […] Initial treatments include maintenance of adequate oxygen saturation, hemodynamic stability, and correction of electrolyte abnormalities.

Accordingly, the present paper aims to provide an update with recommendations based on the most currently accepted concepts in the management of AMI. […] When the diagnosis of AMI is made, fluid resuscitation should commence immediately to enhance visceral perfusion. Electrolyte abnormalities should be corrected, and nasogastric decompression initiated. […] Broad-spectrum antibiotics should be immediately administered. […] Prompt laparoscopy/laparotomy should be done for patients with an overt peritonitis. […] The goal of surgical intervention for AMI includes: 1) Re-establishment of the blood supply to the ischemic bowel. 2) Resection of all non-viable regions. 3) Preservation of all viable bowel. […] Revascularization when relevant has an essential role in the multidisciplinary approach to AMI.

Acute mesenteric ischemia (AMI) is typically defined as a group of diseases characterized by an interruption of the blood supply to varying portions of the small intestine, leading to ischemia and secondary inflammatory changes. […] Early diagnosis and timely surgical intervention are the cornerstones of modern treatment and are essential to reduce the high mortality associated with this entity. […] Some of the key points include the prompt use of CT angiography to establish the diagnosis, evaluation of the potential for revascularization to re-establish blood flow to ischemic bowel, resection of necrotic intestine, and use of damage control techniques when appropriate to allow for re-assessment of bowel viability prior to definitive anastomosis and abdominal closure. […] When the diagnosis of AMI is made, fluid resuscitation should commence immediately to enhance visceral perfusion. Electrolyte abnormalities should be corrected, and nasogastric decompression initiated.
- #7 Acute Mesenteric Ischemia in the ED: Diagnosis and Treatmenthttps://www.ebmedicine.net/topics/abdominal/emergency-medicine-mesenteric-ischemia
Acute mesenteric ischemia (AMI) is a potentially catastrophic cause of abdominal pain that is likely underdiagnosed in ED patients due to its sometimes vague and variable symptoms. […] In most cases, urgent referral will be required, although managing only a patients cardiac comorbidities may mask their dangerous mesenteric ischemia. […] The value of laboratory testing for patients with suspected AMI. […] The imaging recommendations for prompt diagnosis. […] Treatment: Aggressive Fluid Administration, Address Metabolic Derangements, Antibiotics, Anticoagulation, Analgesia, Avoidance of Vasopressors, Alleviate Stomach, Avoid Supraphysiologic Oxygenation, Advance Directives, Abdominal Compartment Syndrome. […] You wonder whether this could represent acute mesenteric ischemia, and what treatment you should implement immediately. […] You wonder what additional resuscitative measures you could take in the ED, and whether any advanced therapies might benefit this patient.

- #9 Acute Mesenteric Ischemia Medication: Vasodilators, Thrombolytics, Anticoagulants, Antibiotics, Analgesicshttps://emedicine.medscape.com/article/189146-medication
Drug types used in the treatment of acute mesenteric ischemia (AMI) include vasodilators, thrombolytics, anticoagulants, antibiotics, and analgesics. Therapeutic drugs (except for analgesics and prophylactic antibiotics) should be withheld until the type of AMI present has been determined by means of computed tomography (CT) or angiography. […] Vasodilators dilate the mesenteric arterial system, thereby reversing reactive arterial vasospasms in AMI. […] Thrombolytics are angiographically infused to lyse thrombi. They are used in selected patients with embolic AMI. […] Anticoagulants are indicated for preventing further extension of thrombus in mesenteric venous thrombosis (MVT) or, after revascularization, in arterial occlusive AMI. […] Antibiotics are administered to prevent or treat sepsis caused by breakdown of the mucosal barrier in bowel necrosis or perforation. […] Analgesics are used to relieve pain caused by bowel ischemia.
- #10 Intestinal ischemia – Diagnosis and treatment – Mayo Clinichttps://www.mayoclinic.org/diseases-conditions/intestinal-ischemia/diagnosis-treatment/drc-20373950
You might need surgery to remove a blood clot, to bypass an artery blockage, or to repair or remove a damaged part of the intestine. Treatment also may include antibiotics and medicines to prevent clots, dissolve clots or widen blood vessels. […] Treatment aims to restore blood flow to your intestine. Your surgeon can bypass the blocked arteries or widen narrowed arteries with angioplasty or by placing a stent in the artery. […] If your intestine shows no damage, you won’t need repair. But you’ll likely need to take medicine that keeps your blood from clotting, called anticoagulant medicine, for about 3 to 6 months.
- #11 Acute Mesenteric Ischemia Treatment & Management: Approach Considerations, Initial Resuscitation and Stabilization, Pharmacologic Therapyhttps://emedicine.medscape.com/article/189146-treatment
Aside from timely diagnosis and treatment of predisposing conditions, there are no known preventive measures for AMI. […] Guidelines for the management of AMI have been published by the World Society of Emergency Surgery. […] Intra-arterial infusion of papaverine through the angiography catheter at the affected vessel is useful for all arterial forms of AMI. […] Thrombolytic agents infused through the angiography catheter can be life-saving for selected patients with AMAE. […] Heparin anticoagulation is the main therapy for MVT. […] Surgical treatment of AMAT (ie, thrombotic AMI) involves exploratory laparotomy, followed by identification of the involved artery and bowel. […] For patients with severe MVT, exploratory laparotomy with assessment of bowel viability is indicated. […] Some experience with percutaneous endovascular interventions has been accumulated. […] A second-look laparotomy is the most reliable method of determining bowel viability.
- #12 Bowel Ischemia – StatPearls – NCBI Bookshelfhttps://www.ncbi.nlm.nih.gov/books/NBK554527/
Broad-spectrum antibiotic therapy with coverage of colonic flora is the recommended intervention to prevent and treat sepsis. […] Based on intestinal ischemia subtypes, suggestions have included different treatment options. […] The data indicate that in patients with acute mesenteric arterial occlusion, an endovascular intervention can be as effective as traditional surgical. […] Catheter-directed thrombolysis is indicated in patients with distal mesenteric embolization or incomplete aspiration embolectomy. […] However, papaverine infusion should not be used simultaneously with heparin due to an increased risk of papaverine precipitation. […] In patients with embolic AMI, the pharmacomechanical thrombolysis is recommended within the 8 hours of symptoms initiation in selected patients.
- #13 Update in management of mesenteric ischemiahttps://pmc.ncbi.nlm.nih.gov/articles/PMC4087969/
Thrombolytic therapy in the management of intestinal ischemia was first reported in 1979 with the successful application of intraarterial streptokinase in the SMA. […] In the subset of patients who suffer from nonocclusive ischemia, intraarterial vasodilator therapy has been largely responsible for the decrease in mortality from 70% in the 1980s to 50%-55% during the last decade. […] Investigational therapy in the treatment of mesenteric ischemia has focused on pharmacologic strategies to treat mesenteric ischemia. […] The dual-hit hypothesis of ischemic injury is comprised of the initial hypoxic episode and then the subsequent reperfusion injury after reestablishment of forward flow. […] In conclusion, mesenteric ischemia, a spectrum of disorders with multiple etiologies still carries significant morbidity and mortality.

Acute mesenteric ischemia (AMI) is a group of diseases characterized by an interruption of the blood supply to varying portions of the intestine, leading to ischemia and secondary inflammatory changes. […] Early diagnosis and timely surgical intervention are the cornerstones of modern treatment to reduce the high mortality associated with this entity. […] Traditionally, AMI has been treated with open surgery. Over the past two decades, the rapid development of endovascular techniques has made this approach an important alternative for patients with occlusion of the superior mesenteric artery (SMA). Some studies have shown that endovascular therapy is associated with lower rates of mortality and bowel resection than the traditional, open approach. […] The assessment and therapy carried out by an interdisciplinary team should keep the time-to-reperfusion interval as short as possible.
- #21 Diagnosis and Management of Acute Mesenteric Ischemia – Endovascular Todayhttps://evtoday.com/articles/2021-jan/diagnosis-and-management-of-acute-mesenteric-ischemia
Although relatively uncommon, mesenteric ischemia is responsible for significant morbidity and mortality in affected individuals. […] The rapid mobilization of a multidisciplinary team consisting of vascular surgeons, general surgeons, intensivists, and radiologists is crucial to address the needs of this critically ill patient population. […] The administration of crystalloid fluid initially, followed by blood as necessary, should start in the emergency department. Broad-spectrum antibiotics directed against normal gut flora should also be given prior to proceeding to the operating room. […] Over the last 20 years, as endovascular techniques have become increasingly sophisticated and practitioners more adept at employing them, minimally invasive approaches to mesenteric ischemia have gained popularity.

They will then inflate the balloon to help restore blood flow, sometimes placing a stent to keep your artery widened; Bypass surgery: With bypass surgery, surgeons take a healthy blood vessel from another part of your body and reattach it to make a new route for blood to flow through; Resection: An intestine resection involves removing damaged parts of your intestines. […] Treatment options for ischemic bowel include medication, bowel rest, and sometimes surgery.
- #29 Bowel Ischemia – MD Searchlighthttps://mdsearchlight.com/health/bowel-ischemia/
Depending on the type of intestinal ischemia, different treatments might be needed. There is evidence that both endovascular intervention (a minimally invasive procedure inside blood vessels) and traditional surgery can be successful in cases of acute mesenteric arterial occlusion (blockage). […] Endovascular intervention includes either drug treatment or mechanical removal of the blockage, such as pulling it out via a large tube (catheter) with a stiff wire. In special cases, drugs that dissolve blood clots are used. Current evidence suggests that certain medications have a lower risk of non-brain bleeding, and so tend to be favored. An initial heparin injection, a blood thinner, helps prevent further clotting. This is followed by warfarin, another blood thinner, administered orally for at least six months.

The mainstay of management of the thromboembolic subtypes of acute mesenteric ischemia involves revascularization of viable bowel tissue, typically achieved through surgery or endovascular approaches, with open surgery being the gold standard of definitive management. […] Endovascular interventions have gained popularity in the management of acute mesenteric ischemia due to the reports of lower laparotomy requirements, reduced bowel resection, and lower mortality rates. […] The Society for Vascular Surgery recommends revascularization for symptomatic patients with chronic mesenteric ischemia, aiming to reverse the presenting symptoms and improve overall quality of life. […] Endovascular revascularization is strongly recommended as the initial treatment in patients with amenable lesions, with open surgical revascularization reserved for patients with lesions not amenable to an endovascular intervention approach.
- #32 Acute Mesenteric Ischemia Treatment & Management: Approach Considerations, Initial Resuscitation and Stabilization, Pharmacologic Therapyhttps://emedicine.medscape.com/article/189146-treatment
Recognition of acute mesenteric ischemia (AMI) before permanent tissue damage occurs is the best way of improving patient survival, and only angiography or exploratory surgery makes early diagnosis possible. […] Treatment options depend on the etiology of intestinal ischemia, as well as on the hemodynamic stability of the patient and the experience/expertise of the treating staff. Generally speaking, nonocclusive AMI is treated medically, whereas occlusive AMI is correctable with surgery. Definitive treatment options include the following: […] All cases of mesenteric ischemia with signs of peritonitis or possible bowel infarction, regardless of etiology, generally warrant immediate surgical intervention for the resection of ischemic or necrotic intestines. […] Surgical treatment may be contraindicated if the risks from comorbid conditions preclude survival after general anesthesia. If the ischemia is thought to be caused by vasospasm, surgery is not indicated. Medical management with anticoagulants and intra-arterial vasodilators is appropriate.
- #33 Intestinal ischemia – Wikipediahttps://en.wikipedia.org/wiki/Intestinal_ischemia
Treatment of acute ischemia may include stenting or medications to break down the clot provided at the site of obstruction by interventional radiology. Open surgery may also be used to remove or bypass the obstruction and may be required to remove any intestines that may have died. If not rapidly treated outcomes are often poor. Among those affected even with treatment the risk of death is 70% to 90%. […] In those with chronic disease bypass surgery is the treatment of choice. Those who have thrombosis of the vein may be treated with anticoagulation such as heparin and warfarin, with surgery used if they do not improve. […] The treatment of intestinal ischemia depends on the cause and can be medical or surgical. However, if bowel has become necrotic, the only treatment is surgical removal of the dead segments of bowel.

Surgical revascularisation remains the treatment of choice for intestinal ischaemia related to an occlusion of the vessels supplying the bowel, but thrombolytic medical treatment and vascular interventional radiological techniques have a growing role. […] If the ischemia has progressed to the point that the affected intestinal segments are gangrenous, a bowel resection of those segments is called for. Often, obviously dead segments are removed at the first operation, and a second-look operation is planned to assess segments that are borderline that may be savable after revascularization.

Endovascular revascularization procedures are the primary option in cases of arterial occlusion when sufficient expertise is available. […] Damage control surgery (DCS) with temporary abdominal closure is an important adjunct for patients who require intestinal resection allowing reassessment of bowel viability and in situations of severe abdominal sepsis. […] Mesenteric venous thrombosis can often be successfully treated with a continuous infusion of unfractionated heparin. […] When NOMI is suspected, the focus is to correct the underlying cause and improve mesenteric perfusion. Infarcted bowel should be resected promptly. […] Postoperative intensive care of AMI patients is directed toward the improved intestinal perfusion and the prevention of a multiple organ failure. […] Treatment of AMI is optimal in a dedicated center using a focused care bundle and a multidisciplinary team. […] Patients undergoing revascularization should have surveillance imaging and long-term anticoagulation.

Treatment of acute ischemia may include stenting or medications to break down the clot provided at the site of obstruction by interventional radiology. Open surgery may also be used to remove or bypass the obstruction and may be required to remove any intestines that may have died. If not rapidly treated outcomes are often poor. Among those affected even with treatment the risk of death is 70% to 90%. […] In those with chronic disease bypass surgery is the treatment of choice. Those who have thrombosis of the vein may be treated with anticoagulation such as heparin and warfarin, with surgery used if they do not improve. […] The treatment of intestinal ischemia depends on the cause and can be medical or surgical. However, if bowel has become necrotic, the only treatment is surgical removal of the dead segments of bowel.

The mainstay of management of the thromboembolic subtypes of acute mesenteric ischemia involves revascularization of viable bowel tissue, typically achieved through surgery or endovascular approaches, with open surgery being the gold standard of definitive management. […] Endovascular interventions have gained popularity in the management of acute mesenteric ischemia due to the reports of lower laparotomy requirements, reduced bowel resection, and lower mortality rates. […] The Society for Vascular Surgery recommends revascularization for symptomatic patients with chronic mesenteric ischemia, aiming to reverse the presenting symptoms and improve overall quality of life.

Chronic mesenteric ischemia (CMI), commonly referred to as „intestinal angina” is an uncommon vascular condition with an insidious onset that often leads to severe debilitating abdominal symptoms. […] Since its introduction by Shaw et al. in 1958, open surgical repair (OSR) has been the standard of treatment for CMI. […] In years since, multiple studies have reported that percutaneous endovascular treatment (PVET) of CMI is possible with a high technical success rate and with minimal complications in properly selected patients. […] As a result, PEVT has supplanted OSR as the default treatment for CMI in many centers across the United States, especially in patients with severe cardiovascular co-morbidities.

- #81 Intestinal Ischemia Surgery & Treatmenthttps://lacolon.com/article/intestinal-ischemia-surgery
At a basic level, the goal of treatment for intestinal ischemia is to restore blood flow to the area of the intestine that has been affected. […] The treatment for mild, non-gangrenous colonic ischemia is supportive and includes things like bowel rest and IV fluids. The treatment for severe gangrenous ischemia is broad-spectrum antibiotics and surgery where the surgeon will remove the affected part of your gut. […] The treatment for acute mesenteric ischemia begins with supportive care, which includes IV fluids, nasogastric tube placement, and food restriction. Initial treatment also includes broad-spectrum antibiotics and heparin, which is a drug that helps prevent any more clots from forming. […] The treatment for chronic mesenteric ischemia involves eating frequent but smaller meals and choosing low-fat foods. Patients are also advised to reduce their risk of developing severe gut ischemia by maintaining a healthy lifestyle and quitting smoking.
- #82 Ischemic Colitis: Symptoms & Treatmenthttps://my.clevelandclinic.org/health/diseases/24513-ischemic-colitis
If you’re recovering from an acute episode of ischemic colitis, your healthcare provider will recommend no food at first. After that, you may transition to a liquid diet and eventually a soft diet. Avoid foods high in fiber for now. The idea is to make your intestines work as little as possible while they’re healing. Digestion requires more blood flow and oxygen to the area, while bowel rest gives your body the chance to restore that blood supply. If you have long-term (chronic) ischemic colitis or another chronic condition that predisposes you to ischemic colitis, your healthcare provider may give you specific long-term guidelines.

Surgical revascularization for visceral ischemia due to an occluded SMA was first described by Shaw et al in 1958, in which they reported two successful cases of mesenteric thromboendarterectomy. […] For chronic occlusive disease, when revascularization is considered, single-vessel bypass to the superior mesenteric artery has been very successful, even in patients with multiple-vessel occlusions. […] Antegrade aortoceliac bypass and transaortic endarterectomy have been successful for poor-risk patients, and are usually adequate for multiple outflows. […] Since the first reports of percutaneous transluminal angioplasty of the visceral vessels in 1980, endovascular therapy for atherosclerotic disease has rapidly expanded in both scope and indication in the last ten years. […] In both the acute and chronic presentation of intestinal ischemia, endoluminal therapy has emerged as a main, if not first-line therapy.

Initial therapy of CMI should be directed towards controlling underlying risk factors such as diabetes, hypertension, and hypercholesterolemia. […] Ultimately, most patients with CMI require revascularization, and medical management alone is usually reserved for patients who are too high risk for any revascularization options (surgical or percutaneous), or who have refractory symptoms despite failed previous revascularization attempts. […] As mentioned above, PEVT currently has a Class IB ACC/AHA recommendation for the treatment of CMI. […] Once a decision towards revascularization is made, careful consideration must be made towards selecting which vessel(s) to revascularize in situations where more than one vessel is significantly stenosed. […] Studies have shown that recanalization of the SMA has the highest likelihood of providing lasting benefit.

The goal of chronic mesenteric ischemia treatment is to restore blood flow to your intestines before damage occurs. […] If diet changes do not help and symptoms cause weight loss, long-term abdominal pain, and even food fear your doctor at the UPMC Heart and Vascular Institute may recommend minimally invasive or open surgical treatments to increase blood flow to your intestines. […] Your doctor will insert a balloon-tipped catheter inside the blocked artery at the point of the blockage. […] To make sure the artery stays open, your doctor may place a stent. A stent is a metal-mesh tube that acts as a scaffold by pressing against the artery walls, keeping the artery open. […] An option when angioplasty is ineffective or when more than one blood vessel is blocked. […] Increases blood flow from the aorta to the blood vessels, supplying the bowel beyond the areas of narrowing.

However, if the SMA cannot be treated by endovascular means (e.g., due to calcification or presence of an ostial or long occlusion), an attempt at celiac angioplasty can be beneficial. […] Once a vessel is identified for revascularization, the decision to conduct plain balloon angioplasty versus primary stenting must be made. […] The overall complication rate of PEVT is low (0-10%), and is mostly attributed to access site complications, including access site hematoma, AV fistula, pseudoaneurysm, etc. […] Acute intestinal ischemia secondary to embolization, thrombosis, or dissection is the most feared complication of mesenteric endovascular intervention. […] In a nationwide United States inpatient sample of 5583 medicare beneficiaries (1988-2006) undergoing revascularization for CMI, PEVT was performed in 62% patients. […] Once diagnosed, treatment options include PEVT and OSR. […] However, for many high surgical risk patients, PEVT is becoming the preferred treatment in atherosclerotic CMI due to reduced peri-operative morbidity and mortality compared to OSR.

Chronic mesenteric ischemia (CMI) arises from the inability to achieve adequate intestinal blood flow after meals, leading to an imbalance between oxygen and metabolite supply and demand. […] The inaugural performance of endovascular revascularization (ER) for visceral vessels took place in 1980. […] Despite the limited quality of available evidence, the consensus among experts is strongly in favor of PMAS over PTA alone for the treatment of atherosclerotic mesenteric artery stenosis. […] There are several key areas of focus for chronic mesenteric ischemia (CMI) treatment. […] Well-designed randomized controlled trials comparing different stent types, such as covered stents versus bare metal stents, are needed to evaluate efficacy, patency rates, and long-term outcomes in CMI patients.

If you’re recovering from an acute episode of ischemic colitis, your healthcare provider will recommend no food at first. After that, you may transition to a liquid diet and eventually a soft diet. Avoid foods high in fiber for now. The idea is to make your intestines work as little as possible while they’re healing. Digestion requires more blood flow and oxygen to the area, while bowel rest gives your body the chance to restore that blood supply.

Ischemic colitis is the most common type of intestinal ischemia, or gut-based blood blockages. […] Most people with ischemic colitis have mild cases and recover well with treatment. […] If you have a mild case (and most cases are mild), the inner lining of your colon is inflamed, sore, and bleeding. It usually heals on its own within 1-2 weeks. […] People with ischemic colitis typically spend a few days in the hospital in the intensive care unit, where doctors can monitor your blood flow. It also helps your colon heal. While in the hospital, you may receive IV antibiotics to prevent infection. […] To give your colon a rest while it heals, you wont be able to drink or eat anything for a few days. Youll get IV fluids and electrolytes to keep you hydrated. Supplemental oxygen can also help your bowel to heal.

Mesenteric ischemia is a condition well-known among physicians treating patients with abdominal symptoms. Even so, mortality rates have not decreased significantly over the last decades. The purpose of this article is to review current treatment concepts of acute and chronic mesenteric ischemia. […] Early diagnosis is one of the most important features that determine a patients prognosis. Conventional angiography and multidetector computed tomography are therefore appropriate to quickly diagnose mesenteric ischemia, the latter being commonly more available. Once a patient presents with signs of peritonitis, instant laparotomy is indicated, and infarcted bowel segments need to be resected, followed by a second-look operation if necessary. If bowel necrosis is clinically not suspected, different approaches should be applied according to source and nature of mesenteric ischemia. Besides established surgical treatment concepts, more and more interventional procedures are developed and evaluated. However, superiority of these new techniques could only be shown for selected patient groups so far. In chronic mesenteric ischemia, interventional approaches seem to be an attractive alternative in patients who are in a condition too bad to undergo surgery. Patients with colonic ischemia are treated best in a conservative manner and by resolving the underlying cause, if identified.
