Background: Acute Pancreatitis is one of the most common disease in all parts of INDIA. The morbidity and mortality of the disease can be reduced by early detection of complications. In rural health centres, authors need a simple and easily accessible and reproducible scoring system to access the severity. The main aim of the study is, using BISAP score authors can easily identify the severity and complications of acute pancreatitis as early as possible even in rural health centres. Methods: This is a prospective study conducted at Koppal District Hospital, Karnataka. Authors included 80 acute pancreatitis patients admitted in present hospital from July 2015 to July 2017. BISAP score is used within 24 hours of admission to access the severity and complications of the pancreatitis. Complications are accessed with respect to duration of hospital stay, organ failure and necrotising pancreatitis against BISAP score less than 3 and more than 3. Results: In present study male (83.75%) patients are more affected than females (16.25%). Alcohol (52.5%) being the main culprit then biliary (32.5%) and idiopathic (15%) as causes of acute pancreatitis. Middle age group between 30 to 50 years (66.25%) are more affected. Severe pancreatitis features like organ failure (66.67%) and necrotising pancreatitis (71.4%) are seen in patients with score more than 3. And also, the duration of inpatient hospital stay is longer (more than 5 day) in same patients. Conclusions: Acute pancreatitis is one of the most common causes for acute abdomen and alcohol consumption being the main culprit in rural areas of south India. Of the many scoring systems, BISAP score can be easily done at rural health centres to early detection of severity and complication of acute pancreatitis.
