          Abstract

          Background

          Acute pancreatitis (AP) is a common cause of emergency hospital admission. Predictive value of biochemical markers including alanine aminotransferase (ALT), alkaline phosphatase (ALP), bilirubin and lipase on pancreatitis has not been fully established. This study aimed to assess the role of ALT, ALP, bilirubin and lipase levels at admission on predicting the aetiology and length of hospital stay in AP. This study also assesses quantitative high lipase as a predictor of gallstone pancreatitis (GP).

          Methods

          All patients above the age of 18 with a diagnosis of AP between October 2016 - 2017 were included in our study. The exclusion criteria were patients with a known history of pancreatitis or biliary disease/bile duct stones and pregnancy. This is a retrospective study performed from a prospectively collected electronic patient database at our hospital.

          Results

          Among the 143 patients with AP, 50 patients were diagnosed with gallstone pancreatitis (GP) and the remaining of 93 patients suffered non-gallstone pancreatitis (NGP). Mean ALT level was significantly higher in gallstone pancreatitis (237 ± 351 IU) compared to non-gallstone pancreatitis (107 ± 162 IU; P = 0.005). ALP level was numerically high in GP (151.5 ± 186) compared to NGP (138 ± 105 IU; P = 0.64). Similar results in bilirubin level also noted in GP (35.5 ± 24.5) comparing to NGP (20.7 ± 79.6 µmol/L; P = 0.09).

          Raised ALT (9.3 ± 8.2 versus 3 ± 2.19 days), bilirubin (8.5 ± 2.5 versus 6.9 ± 1.19 days) and ALP levels (6.26 ± 6.1 versus 3.5 ± 10 days respectively; P = 0.05) were associated with longer hospitalisation in GP comparing to NGP. The lipase level more than 10 times the upper reference level (10-URL) was found to be associated with GP (39/50) than NGP (54/93; P = 0.027).

          Conclusion

          Raised ALT, high lipase of 10 URL levels were associated with gallstone pancreatitis. In gallstone pancreatitis, patients with high ALT, bilirubin and ALP levels had longer hospital stay.

          American College of Gastroenterology guideline: management of acute pancreatitis.

          This guideline presents recommendations for the management of patients with acute pancreatitis (AP). During the past decade, there have been new understandings and developments in the diagnosis, etiology, and early and late management of the disease. As the diagnosis of AP is most often established by clinical symptoms and laboratory testing, contrast-enhanced computed tomography (CECT) and/or magnetic resonance imaging (MRI) of the pancreas should be reserved for patients in whom the diagnosis is unclear or who fail to improve clinically. Hemodynamic status should be assessed immediately upon presentation and resuscitative measures begun as needed. Patients with organ failure and/or the systemic inflammatory response syndrome (SIRS) should be admitted to an intensive care unit or intermediary care setting whenever possible. Aggressive hydration should be provided to all patients, unless cardiovascular and/or renal comorbidites preclude it. Early aggressive intravenous hydration is most beneficial within the first 12-24 h, and may have little benefit beyond. Patients with AP and concurrent acute cholangitis should undergo endoscopic retrograde cholangiopancreatography (ERCP) within 24 h of admission. Pancreatic duct stents and/or postprocedure rectal nonsteroidal anti-inflammatory drug (NSAID) suppositories should be utilized to lower the risk of severe post-ERCP pancreatitis in high-risk patients. Routine use of prophylactic antibiotics in patients with severe AP and/or sterile necrosis is not recommended. In patients with infected necrosis, antibiotics known to penetrate pancreatic necrosis may be useful in delaying intervention, thus decreasing morbidity and mortality. In mild AP, oral feedings can be started immediately if there is no nausea and vomiting. In severe AP, enteral nutrition is recommended to prevent infectious complications, whereas parenteral nutrition should be avoided. Asymptomatic pancreatic and/or extrapancreatic necrosis and/or pseudocysts do not warrant intervention regardless of size, location, and/or extension. In stable patients with infected necrosis, surgical, radiologic, and/or endoscopic drainage should be delayed, preferably for 4 weeks, to allow the development of a wall around the necrosis.

              Trends in the epidemiology of the first attack of acute pancreatitis: a systematic review.

              To systematically review trends in the epidemiology of the first attack of acute pancreatitis (AP) based on reported population-based studies. From Medline, we retrieved 18 full-length English language peer-reviewed original articles published from 1966 to June 2005 with population-based information on the epidemiology of first-attack AP. Trends over time were analyzed based on study- and country-specific data and the study site (UK vs non-UK). Eight studies were from the UK and 10 from other European centers. An increase in the annual incidence per 100,000 for first-attack AP was reported in 10 of 12 studies with longitudinal data from 4 countries (UK, Sweden, Denmark, and Netherlands). The overall AP incidence seems to be higher in non-UK studies compared with that of UK, partly explained by a higher incidence of alcoholic pancreatitis in non-UK studies. A linear trend for increase in gallstone pancreatitis incidence over time was observed irrespective of the study site (UK or non-UK). The AP incidence and mortality increased with age. Gallstone pancreatitis was more common in female subjects, and alcoholic pancreatitis was more common in middle-aged male subjects. The AP case fatality (%) has decreased over time, but the overall population mortality rate per 100,000 has remained unchanged. Recurrence after the first attack is milder with a substantially lower mortality. The incidence of AP seems to be increasing. Differences in the incidence and etiology between and within countries reflect differences in the risk factor prevalence. Case-fatality rate, but not the population-based mortality rate, decreased over time.
