Zaparcie
Rokowania, prognozy i postęp choroby

Zaparcie funkcjonalne u dzieci definiuje się przez obecność co najmniej 2 z 6 kryteriów, takich jak częstotliwość wypróżnień ≤3/tydzień, twarde i duże stolce, nietrzymanie kału, celowe powstrzymywanie defekacji oraz zatrzymywanie stolca. Długoterminowa obserwacja wykazała, że około 80% pacjentów w wieku 16 lat osiąga dobre wyniki kliniczne, a po tym wieku odsetek ten stabilizuje się na poziomie 75%. Czynniki ryzyka złego rokowania obejmują starszy wiek przy wystąpieniu objawów (OR 1,15; 95% CI 1,02-1,30; P=0,04), dłuższy czas od pojawienia się objawów do pierwszej wizyty w poradni (OR 1,24; 95% CI 1,10-1,40; P=0,001) oraz niższą częstość wypróżnień na początku obserwacji (OR 0,92; 95% CI 0,84-1,00; P=0,03). Pomiar czasu pasażu jelitowego (CTT) ma istotne znaczenie prognostyczne: CTT <100 godzin koreluje z lepszym rokowaniem, natomiast CTT ≥100 godzin wskazuje na gorsze wyniki po roku obserwacji. Prawidłowy CTT ma 100% negatywną wartość predykcyjną dla prawidłowej manometrii okrężnicy, co ogranicza wskazania do tego badania u pacjentów z prawidłowym czasem pasażu.

Prognoza zaparcia (Constipation Prognosis)

Zaparcie funkcjonalne to częsta dolegliwość wieku dziecięcego, definiowana przez obecność co najmniej 2 z 6 kryteriów: częstotliwość wypróżnień ≤3/tydzień, twarde stolce, duże rozmiary stolca, nietrzymanie kału, celowe powstrzymywanie defekacji oraz zatrzymywanie stolca.1 Rokowanie w przypadku zaparć jest uzależnione od wielu czynników, a właściwa ocena prognostyczna pomaga w planowaniu optymalnego leczenia.

Rokowanie u dzieci i młodzieży

Długoterminowa obserwacja dzieci z zaparciem funkcjonalnym wykazała, że dobre wyniki kliniczne osiąga około 80% pacjentów w wieku 16 lat. Po tym wieku odsetek ten pozostaje stały na poziomie 75%, co oznacza, że jedna czwarta dzieci z zaparciem funkcjonalnym nadal doświadcza objawów w wieku dorosłym.2

Zidentyfikowano czynniki ryzyka złego rokowania w wieku dorosłym, które obejmują:

  • Starszy wiek w momencie wystąpienia objawów (iloraz szans [OR]: 1,15 [95% przedział ufności (CI): 1,02-1,30]; P = 0,04)3
  • Dłuższy okres między wystąpieniem objawów a pierwszą wizytą w specjalistycznej poradni (OR: 1,24 [95% CI: 1,10-1,40]; P = 0,001)4
  • Niższa częstość wypróżnień przy rozpoczęciu obserwacji (OR: 0,92 [95% CI: 0,84-1,00]; P = 0,03)5

Te wyniki wskazują, że skierowanie do specjalistycznej poradni powinno być rozważone na wczesnym etapie u dzieci, które nie reagują na leczenie pierwszego rzutu, co może poprawić długoterminowe rokowanie.6

Czynniki prognostyczne w ocenie zaparcia

W ocenie rokowniczej zaparcia istotną rolę odgrywają badania diagnostyczne, w tym pomiar czasu pasażu jelitowego (CTTColonic Transit Time). Badania wykazały, że obecność wpuklenia odbytnicy (rectal impaction) przy pierwszej ocenie wiąże się z lepszym rokowaniem po roku obserwacji.7

Wyniki CTT mają istotne znaczenie prognostyczne:

  • Pacjenci z CTT <100 godzin mają lepsze rokowanie po roku obserwacji8
  • CTT ≥100 godzin wiąże się z gorszym rokowaniem po roku obserwacji9

Ważne jest również, że prawidłowy czas pasażu jelitowego (CTT) ma 100% negatywną wartość predykcyjną dla prawidłowej manometrii okrężnicy, co sugeruje, że u pacjentów z prawidłowym czasem pasażu jelitowego manometria okrężnicy nie wnosi dodatkowej wartości diagnostycznej ani terapeutycznej.10 Oznacza to, że u pacjentów z prawidłowym wynikiem badania markerów nieprzeziernych dla promieni RTG manometria okrężnicy nie ma wartości dodanej w oparciu o wyniki badań eksploracyjnych.11

Zaparcie a ryzyko sercowo-naczyniowe u osób starszych

Badania przeprowadzone na dużej kohorcie australijskich pacjentów szpitalnych w wieku ≥60 lat (n=541,172) wykazały, że zaparcie jest pozytywnie i niezależnie związane z nadciśnieniem tętniczym oraz że te dwa czynniki wchodzą w interakcję, modyfikując ryzyko zdarzeń sercowo-naczyniowych.12

Zaobserwowano następujące zależności:

  • Pacjenci z zaparciem mieli wyższe skorygowane wielowymiarowo ryzyko nadciśnienia tętniczego (OR: 1,96; 95% CI: 1,94-1,99; P<0,001)13
  • W porównaniu do pacjentów bez zaparcia i bez nadciśnienia tętniczego, wyższe skorygowane wielowymiarowo ryzyko zdarzeń sercowo-naczyniowych odnotowano u pacjentów z:
    • Samym zaparciem (OR: 1,58; 95% CI: 1,55-1,61; P<0,001)14
    • Samym nadciśnieniem tętniczym (OR: 6,12; 95% CI: 5,99-6,26; P<0,001)15
    • Zarówno zaparciem, jak i nadciśnieniem tętniczym – ryzyko zdarzeń wydawało się być addytywne (OR: 6,53; 95% CI: 6,40-6,66; P<0,001)16

Te odkrycia sugerują, że interwencje mające na celu leczenie zaparcia mogą zmniejszyć ryzyko sercowo-naczyniowe u starszych pacjentów.17 Wśród pacjentów szpitalnych w wieku 60 lat lub starszych, zaparcie wiąże się ze zwiększonym ryzykiem nadciśnienia tętniczego, udaru mózgu, zawału mięśnia sercowego oraz wszystkich zdarzeń sercowo-naczyniowych.18

Przebieg i powikłania przewlekłego zaparcia

Przewlekłe pierwotne zaparcie zwykle ma łagodny przebieg. Jednak poza wpływem na jakość życia pacjentów, może czasami powodować różne powikłania, takie jak:19

  • Objawy wzdęcia i bóle brzucha
  • Niedrożność jelit spowodowana upakowaniem mas kałowych w jelicie (jest to sytuacja niezwykle rzadka)
  • Hemoroidy i powiązane objawy (krwawienie, ból)
  • Szczelina odbytu (bolesna rana w odbycie)
  • Enterocele lub rectocele (obniżenie lub wypadanie pochwy, albo przepuklina jelita lub odbytnicy do pochwy)

Szczególnie istotne jest rozpoznanie objawów alarmujących, które wymagają konsultacji lekarskiej, takich jak: nagła zmiana rytmu wypróżnień, utrata masy ciała czy krew w kale – w celu wykluczenia możliwości, że zaparcie jest wtórne lub uległo pogorszeniu z powodu innego procesu chorobowego.20

Wpływ leczenia na rokowanie

Leczenie zaparcia funkcjonalnego wymaga kombinacji edukacji rodziców i pacjenta, interwencji żywieniowej, interwencji behawioralnej, farmakoterapii, ścisłej obserwacji i długoterminowej zgodności z reżimem terapeutycznym.21 Wieloaspektowe podejście do leczenia zaparcia przekłada się na lepsze wyniki terapeutyczne i przyczynia się do korzystniejszego rokowania długoterminowego.

Proces terapeutyczny powinien być zindywidualizowany i dostosowany do specyficznych czynników prognostycznych zidentyfikowanych u danego pacjenta. Wczesna interwencja, szczególnie u dzieci z objawami zaparcia, może znacząco poprawić długoterminowe rokowanie i zapobiec utrzymywaniu się dolegliwości w wieku dorosłym.22

    These findings suggest that interventions to address constipation may reduce cardiovascular risk in elderly patients. […] In an Australian cohort comprising 541,172 hospital patients aged 60 years, we found that constipation was positively and independently associated with hypertension, and that the two factors interacted to modify the risk of cardiovascular events. […] Patients with either constipation or hypertension alone had an increased risk of myocardial infarction, stroke and all cardiovascular events, compared to patients with neither condition. […] Patients with both constipation and hypertension had an even higher risk of cardiovascular events. […] Constipation was also associated with a higher prevalence of chronic hypertension and thus it is possible that the latter condition represents a mediator of cardiovascular events in patients with constipation. […] In conclusion, among hospital patients aged 60 years or older, constipation is linked to an increased risk for hypertension, stroke, myocardial infarction, and all cardiovascular events.

  • #19 Constipation prognosis | Hospital Clínic Barcelona

    Chronic primary constipation usually has a benign course. However, as well as affecting the quality of life of those who have it, at times it can cause other complications. Amongst them may be the origin of distension symptoms and abdominal pain and may even include an intestinal occlusion due to impaction of faeces in the intestine, although this situation is extremely rare. Furthermore, constipation increases the likelihood of haemorrhoids and associated symptoms (bleeding, pain), anal fissure (a painful wound in the anus), enterocele or rectocele (vaginal descent or collapse, or herniation of the bowel or rectum into the vagina). […] It is also important to know which alarm signs require consultation with a doctor (sudden change in intestinal rhythm, weight loss, blood in the faeces) to exclude the possibility that the constipation is secondary, or has worsened due to another process.
