Outcome of patients with acute severe necrotizing pancreatitisin a dedicated hepato-biliary unit of Pakistan

Objective: To analyze the management of severe necrotizing pancreatitis in a specialized center of a lower middle-income country, Pakistan using multiple outcome measures.

Methods: All the patients in this prospective observational study with severe necrotizing pancreatitis being referred to Pak Emirates Military Hospital from January 2017 to December 2019 were followed over the course of their admission. Demographic data and disease outcomes were duly noted. Cox regression analysis was used to predict fatality outcome.

Results: A total of 57 patients with 48 (84.6%) infected necrotizing pancreatitis were managed in our set up. The most common etiology reported was gall-stones (37%) with male preponderance (72%) and a mean age of 50±11.3 years. The most common complications were acute-kidney-injury (63%), splenic-vein-thrombosis (21%) and ascites (21%). Fourteen patients required mechanical-ventilation with a mean duration of 7±1.4 days on respiratory support. Eight (14%) patients required Endoscopic-Ultra-Sound guided drainage and six (10.5%) underwent surgical-necrosectomy depending upon the patients’ condition and collections characteristics. Mortality, as one of the main outcome measures, was reported to be 12.3% and was statistically related to mechanical-ventilation, organ failure and surgical-necrosectomy while 22 (38.6%) patients were discharged on pancreatic enzymes supplements and 7% required insulin.

Conclusion: Survival outcomes with acute severe necrotizing pancreatitis are improving in a dedicated hepato-biliary unit internationally in lieu with a multidisciplinary team approach. Percutaneous and EUS guided drainage of pancreatic collections have turned out to be an important procedure to manage infected pancreatic necrosis that helps to avoid a morbid procedure in the form of necrosectomy.
