Exploring the Burden and Outcome of Acute Pancreatitis: An Experience from a Tertiary Referral Center

Abstract

Background and Aims: Changing trends are observed in acute pancreatitis (AP); hence, this study was conducted to determine various etiologies, severity, complications, and outcome of AP. Materials and Methods: A retrospective study was conducted on admitted 122 AP patients. Results: The male:female ratio was 1.77. The mean age was 34.11 ± 15.45 years. Various etiologies were alcohol seen in 26.2%, gallstones in 22.1%, postendoscopic retrograde cholangiopancreatography (ERCP) in 15.6%, pancreatic divisum in 4.9%, hypercalcemia in 0.8%, hypertriglyceridemia in 0.8%, viral in 0.8%, worm in 0.8%, and idiopathic in 32.8% of patients. Mild, moderately severe, and severe AP were seen in 46.7%, 36.1%, and 17.2% cases, respectively. Among local complications, peripancreatic collections were seen in 25.4%, pseudocyst or walled-off necrosis in 23.8%, ascites in 26.2%, pleural effusion in 23%, biliary obstruction in 4.9%, vascular thrombosis in 3.3%, intestinal obstruction in 3.3%, upper gastrointestinal bleed in 2.5%, and gastric outlet obstruction in 1.6% of patients. Total 27 patients had organ failure, out of which 6 had transient. Respiratory failure was the most common, followed by renal failure and circulatory failure. Percutaneous drainage was performed in 11 and endoscopic ultrasound-guided drainage in 3 patients. Mortality rate was 6.6%. Conclusions: Common etiologies of AP were idiopathic, alcohol, biliary, and post-ERCP. Mortality was 6.6% attributed to respiratory failure in severe AP.
