Objective. To explore the safety and efficacy of small incision combined with nephroscope surgery in the treatment of infectious pancreatic necrosis. Methods. A retrospective analysis of the clinical data of 37 patients with infectious pancreatic necrosis who underwent small incision combined with nephroscopy in the Department of Hepatobiliary Surgery of Hunan Provincial People’s Hospital from January 2018 to December 2019. Results. All 37 patients successfully completed small incision combined nephroscope surgery. The median time from the onset to the operation of all patients was 38 days (range: 29-80 days), and the hospital stay was 19 days (range: 3-95 days).
