The management of a remnant pancreatic stump for preventing the development of postoperative pancreatic fistulas after distal pancreatectomy: current evidence and our strategy

Abstract

Distal pancreatectomy (DP) is the most common surgical procedure for treating benign and malignant lesions in the body or tail of the pancreas. Although the mortality rate related to DP has recently been reduced, the postoperative morbidity remains high. The most frequent and dismal complication occurring after DP is the development of postoperative pancreatic fistulas (POPF). Several resection methods and closure techniques for treating remnant pancreas have been developed in an effort to reduce the incidence of complications, especially POPF. However, the optimal procedure has not yet been established. In this review, we summarize the current clinical data and evidence for surgical techniques and perioperative management strategies for preventing POPF after DP. Finally, we introduce our non-closure technique for managing remnant pancreatic stumps.
