  Acute pancreatitis is an inflammatory condition of the exocrine pancreas that is a common indication for hospital admission and has had an increasing incidence in the last few decades. The diagnosis of acute pancreatitis requires the satisfaction of two out of three criteria: (1) abdominal pain radiating to the back, (2) serum lipase or amylase levels three or more times the upper limit of the normal level, and (3) findings indicating pancreatitis obtained via a computed tomography (CT) scan or magnetic resonance imaging (MRI). […] The initial investigation includes serum amylase and lipase analysis, a lipid panel including triglycerides, analysis of immunoglobulins, a full blood count, electrolyte analysis, a hemoglobin A1c test, a complete metabolic panel, and transabdominal ultrasound.

  Acute pancreatitis typically presents with severe sudden-onset mid-epigastric or left upper quadrant abdominal pain, which often radiates to the back. Nausea and vomiting is seen in 80% of patients. […] The diagnosis is confirmed in most patients by elevated serum lipase or amylase (3 times upper limit of normal). Contrast-enhanced computed tomography (CECT) is only required where there is diagnostic doubt or a failure to improve within 72 to 96 hours from onset of symptoms. […] Diagnostic investigations include serum lipase or amylase, FBC and differential, C-reactive protein (CRP), urea/creatinine, pulse oximetry, LFTs, CXR, transabdominal ultrasound, and serum calcium. […] Investigations to consider include serum triglycerides, abdominal CT scan (CECT), endoscopic ultrasound (EUS), magnetic resonance cholangiopancreatography (MRCP), and arterial blood gas. […] Emerging tests include urinary trypsinogen-2 and serum IL-6 and IL-8.

  People suffering from the acute onset of a persistent, diffuse abdominal pain or acute epigastric pain should be diagnosed for acute pancreatitis. Therefore, it is important to know the diagnostic accuracy of serum lipase, serum amylase, urinary trypsinogen-2, and urinary amylase, either alone or in combination, for the diagnosis of AP. The accurate diagnosis of AP, the early assessment of the severity of AP, and the identification of the etiology are criteria that should be met by an ideal laboratory test in assessing the condition of a patient with AP. Currently, no biochemical test has been identified that fulfills the above-mentioned criteria and can be considered the “gold standard” for the diagnosis and evaluation of the severity of AP. Nonetheless, the relevant and currently commonly used laboratory tests in the diagnosis of AP are serum lipase and serum amylase. Based on multiple studies, lipase serum has been found to be a more reliable indicator of AP than serum amylase, whereas a reliable early diagnosis of AP is assured by urinary strip tests for trypsinogen-2 and trypsinogen activation peptide (TAP). Other enzymes used in the diagnosis of AP, such as pancreatic isoamylase, immunoreactive trypsin, chymotrypsin, or elastase, are not better than lipase; furthermore, they are more inconvenient and expensive. Measurement of the levels of the aforementioned enzymes should be reserved for situations of uncertain diagnosis. Neither enzyme assay is associated with the severity of AP and cannot precisely predict the consecutive clinical course of the patient. According to Al-Bahrani and Ammori, a biliary etiology is reliably predicted by early transient hypertransaminasemia, whereas a reliable predictor of alcoholic etiology is serum carbohydrate-deficient transferrin. Urinary enzymes are less significant in clinical practice than serum enzymes among the adults. However, urinary enzymes can be used in the case of AP in children. Nevertheless, it is worth knowing all the available diagnostic methods.

  The study by Rompianesi et al. compared the diagnostic exactness of serum lipase, serum amylase, urinary amylase, and urinary trypsinogen-2 in the diagnosis of AP. Serum lipase and serum amylase, with a more than three times greater value than the standard threshold level, and urinary trypsinogen-2, with a value higher than the threshold of 50 ng/mL, seem to have similar sensitivities and specificities. Researchers suggest that one of the above-mentioned parameters should have a low threshold, which would allow the initiation of treatment for AP even when the other parameters are normal. Additionally, they conclude that the occurrence of other disease entities should be considered, despite the incorrect results of the above-mentioned parameters, in order to avoid a misdiagnosis of AP. […] In conclusion, the biochemical diagnostic assay with a slightly greater clinical value is serum lipase. Lipase assays are nowadays instant, reliable, practical, more specific, and sensitive, and their price does not significantly exceed the price of amylase assays. The main advantages of serum lipase are the maintenance of elevated levels for a longer time in comparison with amylase, which is used in the case of the patients who initially present to the emergency department a few days after the onset of AP symptoms, and greater sensitivity in AP caused by alcohol overuse. The serum amylase assay is also performed in the diagnosis of AP, but it has a lower clinical value due to its greatest disadvantage, which is overall low specificity. A normal serum amylase should usually rule out the diagnosis of AP, except for AP secondary to hyperlipidemia and acute exacerbation of chronic pancreatitis, and when the assessment of amylase is delayed in the course of the disease. Nevertheless, the assessment of serum amylase has some advantages, such as inexpensiveness, ready availability, simple automated methods, and high sensitivity. The measurement of serum lipase is not affected by hypertriglyceridemia, but some drugs (for instance furosemide) give a possibility of increasing the serum activity. Other causes of increase are renal insufficiency, chronic pancreatitis, acute cholecystitis, or bowel obstruction.

  According to a clinical practice guideline, published in 2016 by Greenberg et al., concerning the management of acute pancreatitis, in all patients with suspicion of acute pancreatitis a level of serum lipase should be tested because of its slightly higher sensitivity in comparison with other serum and urine tests. The diagnosis of acute pancreatitis is made when a serum lipase activity is at least three times greater than the upper limit of normal. A serum amylase test is also performed in the diagnostics of AP, but it has a lower clinical value. The key blood biochemical parameter in the detection of acute pancreatitis is a serum lipase, which is characterized by an earlier and longer-lasting elevation than a serum amylase. Specifically, the lipase level generally stays elevated for up to two weeks, while the amylase level is elevated for up to five days. Additionally, a serum lipase test has a slightly higher sensitivity compared to the amylase test. At day 0–1 from the onset of symptoms, 100% is reached for lipase, while it is 95% for amylase. For day 2–3, the sensitivity ranges from 85%, whereas the specificity approximates 82% for lipase, in comparison to 68% for amylase. Based on the presented results, it can be concluded that lipase is particularly useful in the case of a delay between the time the patient seeks medical attention and onset of the symptoms. As reported by The American College of Gastroenterology in 2013, the measurement of both serum lipase and serum amylase does not demonstrate advantages in either treatment or profitability. Additionally, serum lipase has been found to be more sensitive than serum amylase among patients with acute pancreatitis secondary to alcohol abuse. Another research performed by Gwozdz et al. presents the diagnostic values of serum and urine enzyme assays in the recognition of AP. The study compares the diagnostic sensitivities of serum lipase, amylase, trypsinogen, elastase-1, the 2 h-timed urine amylase excretion, and the clearances of amylase and creatinine. All the serum tests showed the same sensitivity at the time of admission; however, in the following days, the serum lipase, trypsinogen, and elastase-1 tests presented considerably higher sensitivity than the serum amylase assay. During the second and following days, the diagnostic value of timed urine amylase excretion did not predominate over the serum amylase, and the ratio of amylase and creatinine clearances completely did not differ from each other.

  Laboratory testing can assist in diagnosis, classify the severity of disease, and predict outcomes. Specific tests that should be ordered at presentation include a complete blood count; a comprehensive metabolic panel including renal and hepatic function; urinalysis; and measurement of lipase, calcium, lactate dehydrogenase, and triglyceride levels. […] Lipase level testing is more sensitive and specific than measuring amylase levels, because amylase is also produced by the salivary glands and levels may be normal in patients with recurrent alcoholic pancreatitis. […] Contrast-enhanced computed tomography (CT) is considered the diagnostic standard for radiologic evaluation of acute pancreatitis because it has demonstrated success in the prediction of disease severity and prognosis. […] Current ACG guidelines recommend that all patients with acute pancreatitis be evaluated using abdominal ultrasonography. […] Nonenhanced magnetic resonance imaging has a sensitivity of 79% and a specificity of 92% compared with CT for the identification of severe pancreatitis. […] The Atlanta criteria use early prognostic signs, organ failure, and local complications to define disease severity.

  To summarize, the crucial information concerning the serum lipase and amylase, have been presented in the table below. […] According to the recommendations, the diagnosis of acute pancreatitis is based on blood tests to determine the level of serum lipase and amylase and imaging techniques: magnetic resonance cholangiopancreatography (MRCP), CT, and US. Measurements of serum and urinary enzymes are used to diagnose the AP, none of them allow the evaluation of the severity of the AP and the accurate prediction of the clinical course of the disease. Nowadays, due to technological development, radiologic imaging plays a more and more significant role in the management of the patient. The above-mentioned imaging techniques provide crucial information for the diagnosis and the course of the disease. Specifically, ultrasonography is recommended as a first and basic imaging test performed in patients with suspected AP in order to confirm or exclude the diagnosis as well as detect the possible cause of the disease, while MRI and CT are useful in diagnosing local complications and discovering the necrosis of the pancreas or in assessing the severity of the AP. The latter two have specific indications; they are performed to broaden the diagnosis or when ultrasound does not visualize the structures properly, making it impossible to make an unequivocal diagnosis. It is worth emphasizing that the diagnosis of AP is as important as the diagnosis of the etiology of AP, which in many cases is associated with an inadequate workup.

  The commonly used classification of AP severity includes the revised Atlanta classification (RAC) and the determinant-based classification (DBC). […] The RAC classifies AP severity into 3 grades: (1) mild AP, accounting for 80-85% of AP, without organ dysfunction and local or systemic complications, usually recovering within 12 weeks, and with a very low mortality rate; (2) moderately severe AP, with transient (48 hours) organ dysfunction and/or local complications, and a low early mortality rate. If necrotic tissue is complicated with infection, the mortality rate will increase; and (3) severe AP (SAP), accounting for 5-10% of AP, accompanied by persistent organ dysfunction (48 hours), and a high mortality rate. […] For the early identification of patients who may develop SAP, more active monitoring and treatment measures are beneficial for improving the prognosis of these patients. […] The levels of hematocrit, serum urea nitrogen, and C-reactive protein in laboratory examination are correlated with the severity of AP, but with low accuracy.

  https://my.clevelandclinic.org/health/diseases/8103-pancreatitis

  Gallstones blocking the pancreatic duct can cause pancreatitis. Gallstones that block the pancreatic duct are one of the most common causes of pancreatitis. […] If you have characteristic symptoms of pancreatitis, a healthcare provider will check your pancreas with blood tests and imaging tests. A pancreas blood test looks for elevated levels of pancreatic enzymes in your blood. If levels are at least three times higher than normal, your provider will suspect pancreatitis. They might confirm the diagnosis with a cross-sectional imaging test, such as a CT scan or MRI. These tests can show swelling and fluid deposits in your pancreas as well as other abnormalities. […] Treatment depends on the cause, whether its acute or chronic and how severe it is. In general, you should always see a healthcare provider for symptoms of pancreatitis. Although some cases of acute pancreatitis may go away on their own, that depends on what caused the condition and how severe it is. In the meantime, most people with acute pancreatitis will need pain relief to get through it. Some people will need emergency treatment for certain causes. And some will need intensive care for complications.

  The diagnosis of AP is based on abdominal pain, serum amylase and/or lipase levels 3-fold the upper normal limits, and radiographic findings consistent with AP. A diagnosis of AP is made when at least two of these three criteria are fulfilled. Acute biliary pancreatitis (ABP) was defined as gallstones or microliths in the common bile duct evident on transabdominal ultrasound, computed tomography, EUS, magnetic resonance cholangiopancreatography, or endoscopic retrograde cholangiography and fulfilment of the AP criteria. Hypertriglyceridemia-induced AP (HTG-AP) was defined as a serum triglyceride level 1,000 mg/dL at the time of admission. Acute alcoholic pancreatitis was diagnosed in cases of alcohol abuse or a chronic drinking history with no other identifiable cause of AP. Presumptive IAP was diagnosed when no cause was found at initial admission. The definition of severity was based on the revised Atlanta classification. We defined mild AP as AP without organ failure or local or systemic complications, severe AP as organ failure lasting 48 hours, and moderately severe AP as AP with transient organ failure (48 hours) or local complications.

  Focal acute pancreatitis is a special type of acute pancreatitis, which diagnosis is based on image showing a focal mass formation in the pancreas. For acute pancreatitis with or without focal inflammatory enlargement, little is known on differences between them. Our purpose was to find differences between focal acute pancreatitis and non-localized acute pancreatitis. […] We reviewed the medical records of a total of 24 patients diagnosed with focal acute pancreatitis by imaging and clinical diagnosis, and 27 cases of acute pancreatitis which manifest non-localized pancreas inflammation were selected as the control group. The differences of the two groups were compared to describe their clinical characteristics. […] Compared with non-localized acute pancreatitis, changes in symptoms, signs and laboratory indicators of focal acute pancreatitis are non-obvious, however, there was no significant difference in the severity of two groups, indicating that we should pay more attention to diagnosis of focal acute pancreatitis in clinical practice.

  Focal AP is a special type of AP that radiographically present as focal inflammatory enlargement of the pancreas, but for focal AP diagnosed by imaging and clinical diagnosis, are there differences in etiology composition, clinical manifestations, history, laboratory tests, compared with non-localized AP, there are few studies. […] The study found that changes in symptoms, signs and laboratory indicators of focal AP are not obvious, when compared with non-localized AP, however, there was no significant difference in the severity of the two groups. […] Compared with patients with non-localized AP, patients with focal AP have a smaller proportion of bloating and abdominal tenderness, and the levels of neutrophil ratio, D-dimer, GGT, amylase, and lipase are lower. However, there was no significant difference in the severity between two groups of patients. Therefore, although focal AP is a limited inflammatory change in imaging, it does not show a milder disease than non-localized AP, on the contrary, focal AP is clinically more difficult to diagnose in a timely and accurate manner due to the insignificance of symptoms and changes in certain laboratory indicators, which requires the attention of clinicians.

  https://www.mdpi.com/2075-4418/12/8/1974

  Two phases of AP have been identified: early and late, while the severity has been divided into mild, moderate, and severe. Basically, at least two of the following symptoms must be present for a diagnosis of acute pancreatitis: abdominal pain, described as a persistent and severe epigastric pain often radiating to the back with acute onset; activity of the serum lipase or amylase at least three times greater than the upper limit of normal; and the characteristic symptoms of acute pancreatitis detected by ultrasonography (US), computed tomography (CT), or magnetic resonance imaging (MRI). There are two classifications systems of AP: the Determinant-Based Classification of Acute Pancreatitis Severity (DBC) and the Revised Atlanta Classification 2012 (RAC). Patients who have persistent organ failure, categorized as severe AP, have the highest risk of death. Due to that, it is important to predict and diagnose an episode of severe AP. The etiology of AP should be determined on admission. Early initiation of diagnostics to determine the etiology increases the probability of stating a proper diagnosis. Moreover, it enables the implementation of appropriate treatment and methods to prevent complications and allows the taking of measures to prevent subsequent attacks of pancreatitis. The etiology is defined on the basis of a detailed personal and family history of pancreatic disease, physical examination, laboratory serum tests, and imaging. Another measure that should be taken on admission is to predict the outcome of the AP. It is advised to evaluate host risk factors, clinical risk, and response to initial therapy.

  Absolute diagnosis of acute pancreatitis can be difficult. The patient may undergo a physical examination, and a blood test should reveal if the levels of pancreatic enzymes are high. However, it is recommended that the correct diagnosis of acute pancreatitis should be made within 48 hours of admission. […] Prompt diagnosis and treatment of acute pancreatitis are vital in order to reduce the chances of the spread of the illness and the onset of multiple organ failure. A delay in diagnosis or provision of inadequate medical support can be catastrophic.

  How Is Pancreatitis Diagnosed? […] To check for acute pancreatitis, the doctor will probably press on your belly to see if it is tender and check for low blood pressure, low fever, and a rapid pulse. […] To make a diagnosis, your doctor will test your blood to measure two digestive enzymes: amylase and lipase. High levels of these two enzymes mean you probably have acute pancreatitis. […] To diagnose chronic pancreatitis, X-rays or imaging tests such as a CT scan or MRI may show whether the pancreas is calcified. […] Your doctor will take blood samples and check your stool for excess fat, a sign that the pancreas is no longer making enough enzymes to process fat. […] You may also be checked for diabetes.

  According to a clinical practice guideline, published in 2016 by Greenberg et al., concerning the management of acute pancreatitis, in all patients with suspicion of acute pancreatitis a level of serum lipase should be tested because of its slightly higher sensitivity in comparison with other serum and urine tests. The diagnosis of acute pancreatitis is made when a serum lipase activity is at least three times greater than the upper limit of normal. A serum amylase test is also performed in the diagnostics of AP, but it has a lower clinical value. The key blood biochemical parameter in the detection of acute pancreatitis is a serum lipase, which is characterized by an earlier and longer-lasting elevation than a serum amylase. Specifically, the lipase level generally stays elevated for up to two weeks, while the amylase level is elevated for up to five days. Additionally, a serum lipase test has a slightly higher sensitivity compared to the amylase test. At day 0–1 from the onset of symptoms, 100% is reached for lipase, while it is 95% for amylase. For day 2–3, the sensitivity ranges from 85%, whereas the specificity approximates 82% for lipase, in comparison to 68% for amylase. Based on the presented results, it can be concluded that lipase is particularly useful in the case of a delay between the time the patient seeks medical attention and onset of the symptoms. As reported by The American College of Gastroenterology in 2013, the measurement of both serum lipase and serum amylase does not demonstrate advantages in either treatment or profitability. Additionally, serum lipase has been found to be more sensitive than serum amylase among patients with acute pancreatitis secondary to alcohol abuse. Another research performed by Gwozdz et al. presents the diagnostic values of serum and urine enzyme assays in the recognition of AP. The study compares the diagnostic sensitivities of serum lipase, amylase, trypsinogen, elastase-1, the 2 h-timed urine amylase excretion, and the clearances of amylase and creatinine. All the serum tests showed the same sensitivity at the time of admission; however, in the following days, the serum lipase, trypsinogen, and elastase-1 tests presented considerably higher sensitivity than the serum amylase assay. During the second and following days, the diagnostic value of timed urine amylase excretion did not predominate over the serum amylase, and the ratio of amylase and creatinine clearances completely did not differ from each other.

  The diagnosis of acute pancreatitis requires the presence of at least two of the three diagnostic criteria characteristic abdominal pain, elevated serum amylase or lipase, and radiological evidence of pancreatitis. […] Serum concentrations of amylase and lipase rise within hours of the pancreatic injury. A threshold concentration 24 times the upper limit of normal is recommended for diagnosis. […] Serum lipase is now the preferred test due to its improved sensitivity, particularly in alcohol-induced pancreatitis. Its prolonged elevation creates a wider diagnostic window than amylase. […] The diagnosis of acute pancreatitis usually requires a combination of clinical, laboratory and radiological findings. […] A number of international guidelines have suggested two of the following three features are required for the diagnosis: abdominal pain consistent with acute pancreatitis (acute onset of persistent severe epigastric pain often radiating to the back), serum lipase activity (or amylase activity) at least three times greater than the upper limit of normal, characteristic findings of acute pancreatitis on abdominal ultrasound (a CT scan or MRI is considered if the diagnosis is uncertain).

  https://mission-cure.org/chronic-pancreatitis/diagnosing-chronic-pancreatitis/

  Many patients with chronic pancreatitis struggle to get an accurate, timely diagnosis. This is because chronic pancreatitis is a rare disease and there is no one test that can reliably diagnose it. It can also be difficult for doctors to spot the signs of chronic pancreatitis, which may lead to misdiagnosis or delayed diagnosis. […] To diagnose chronic pancreatitis, doctors need to consider a patients medical history and symptoms and rule out other possible conditions (this process is called differential diagnosis). This means that getting a diagnosis can take some time and may require multiple tests. Its important for patients to be honest about their symptoms and for doctors to listen, apply their expertise, and, sometimes, refer patients to a pancreas specialist.

  Chronic pancreatitis (CP) is still far to rarely diagnosed as symptoms are non-specific and training of physicians in clinical pancreatology is dire (26). […] The clinical picture of CP can vary, depending on the underlying etiology, the stage of disease and the age of the patient (5). […] The most important issue for the clinician is to think of the pancreas as a source of these symptoms. Once this connection is made and appropriate laboratory tests (below) and imaging are done, the diagnosis of CP can be easily established or disregarded. […] In summary, there is no single symptom pathognomonic to chronic pancreatitis, i.e. the diagnosis cannot be established solely on the basis of clinical symptoms. However, in the said enigmatic patient, the clinical diagnosis is still very likely.

  The conventional markers of inflammation, i.e. elevated erythrocyte sedimentation rate (ESR) and elevated leucocytes (WBC) are of no use in establishing the diagnosis of CP. […] As chronic pancreatitis cannot be diagnosed with blood tests, the resulting malnutrition could be diagnosed in cases where the patient with CP has already developed pancreatic exocrine insufficiency (PEI). […] There are clinical symptoms indicative of chronic pancreatitis, however, none of them are specific or even pathognomonic. They should make a physician think of the pancreas as a source of the patients symptoms. Laboratory tests are also indicative at best: there is no positive test proving the diagnosis of CP. Very low (LLN) pancreatic serum enzymes can be a sign of significant pancreatic exocrine insufficiency (PEI) with chronic pancreatitis (CP) as a major etiology.

Hypertriglyceridemia-induced AP (HTG-AP) was defined as a serum triglyceride level 1,000 mg/dL at the time of admission. Acute alcoholic pancreatitis was diagnosed in cases of alcohol abuse or a chronic drinking history with no other identifiable cause of AP. Presumptive IAP was diagnosed when no cause was found at initial admission. The definition of severity was based on the revised Atlanta classification. We defined mild AP as AP without organ failure or local or systemic complications, severe AP as organ failure lasting 48 hours, and moderately severe AP as AP with transient organ failure (48 hours) or local complications.

  Two phases of AP have been identified: early and late, while the severity has been divided into mild, moderate, and severe. Basically, at least two of the following symptoms must be present for a diagnosis of acute pancreatitis: abdominal pain, described as a persistent and severe epigastric pain often radiating to the back with acute onset; activity of the serum lipase or amylase at least three times greater than the upper limit of normal; and the characteristic symptoms of acute pancreatitis detected by ultrasonography (US), computed tomography (CT), or magnetic resonance imaging (MRI). There are two classifications systems of AP: the Determinant-Based Classification of Acute Pancreatitis Severity (DBC) and the Revised Atlanta Classification 2012 (RAC). Patients who have persistent organ failure, categorized as severe AP, have the highest risk of death. Due to that, it is important to predict and diagnose an episode of severe AP. The etiology of AP should be determined on admission. Early initiation of diagnostics to determine the etiology increases the probability of stating a proper diagnosis. Moreover, it enables the implementation of appropriate treatment and methods to prevent complications and allows the taking of measures to prevent subsequent attacks of pancreatitis. The etiology is defined on the basis of a detailed personal and family history of pancreatic disease, physical examination, laboratory serum tests, and imaging. Another measure that should be taken on admission is to predict the outcome of the AP. It is advised to evaluate host risk factors, clinical risk, and response to initial therapy.

  Acute pancreatitis remains the leading cause of inpatient care among gastrointestinal conditions. What do we need to know about the diagnosis and treatment? […] An inability to explain the etiology of pancreatitis persists in about a quarter of patients after a typical workup. […] Both EUS and MRI with MRCP have been used for this purpose, and I would say that actually they have both been studied fairly extensively. Of the two, there are several direct comparisons, and when directly compared, EUS has been shown to demonstrate a potential cause for acute pancreatitis much more often than MRI. […] We suggest that EUS be the next test in the algorithm when evaluating patients with unexplained acute pancreatitis. […] One of the reasons why further imaging is important in the setting of unexplained recurrent acute pancreatitis is that a proportion of patients will actually have an underlying malignancy.
