Abstract
BackgroundAcute 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).MethodsAll 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.ResultsAmong 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).ConclusionRaised 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.

Summary
Acute pancreatitis (AP) is a known common cause of acute abdomen, usually needing an emergency hospital admission. The incidence of AP varies between 4.9 and 73.4 cases per 100,000 [1,2]. In UK, the approximate incidence ranges from 15 to 42 cases per 100,000 population [3, 4]. 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.
