Acute Pancreatitis Necrotizing

In this multicenter, double blinded, placebo-controlled, 1:1 parallel group RCT, we propose to evaluate the impact of pancreatic exocrine replacement therapy on patients with acute necrotizing pancreatitis (ANP). We will include patients of 18-60yrs age and both genders with \>50% pancreatic parenchymal necrosis and \>10% loss of body weight. The primary outcome measure is change in BMI at 3 months after enrolment. The intervention will include pancreatic enzyme consisting of 25000 IU of lipase and similar appearing placebo.
