Abstract
Objective Infected pancreatic necrosis is a serious complication of necrotizing pancreatitis. A method of minimally-invasive retroperitoneal infected pancreatic necrosectomy using percutaneous nephroscope was evaluated. Methods 21 patients with acute pancreatitis were treated in our hospital from June 2008 to August 2009. Among 13 patients who developed infected pancreatic necrosis, 6 underwent percutaneous catheter drainage by CT guidance. Then retroperitoneal infected pancreatic necrostectomy using percutaneous nephroscope along the sinus tract were performed after drainage for 5-36 d. Results In these 6 patients, 3 received percutaneous nephroscopic treatment one time, 2 two times and 1 three times. There were no operative mortality and morbidity except that 1 patient developed pseudocyst 6 months after operation. Conclusion Retroperitoneal pancreatic necrosectomy by percutaneous nephroscope is a safe, feasible, minimally-invasive and efficient method for treating infected pancreatic necrosis when the indication and occasion are suitable. This method would be a valid therapeutic option for treating necrotizing pancreatitis. However, further evaluation is necessary.
