Abstract (original English)

Post-operative pancreatic fistula (POPF) is a serious yet far too common complication following distal pancreatectomy (DP), as it affects 20-30% of patients after DP. POPF raises the risk of other complications and causes delays to a patient's oncologic care. In this review, we present the latest data on patient risk factors for developing POPF, such as obesity, smoking, young age, thick pancreas, lack of epidural anesthesia, hypoalbuminemia, and elevated drain amylase levels. Other risk factors that have been identified with irregular consistency include open surgical approach, non-malignant or neuroendocrine tumor pathology, simultaneous splenectomy, simultaneous vascular resection, and long operative time. We also review the consequences of POPF, which include hemorrhage, infection, delayed gastric emptying, re-operation, re-admission, delays in adjuvant chemotherapy initiation, reduced progression-free survival, and reduced overall survival. Finally, we present strategies that have been studied for avoiding POPF after DP, including reducing pressure at the sphincter of Oddi, the use of sealants and patches, optimizing pancreatic transection, strategies for post-operative drain placement, the use of post-operative somatostatin analogues, and pre-clinical studies of experimental devices and techniques that may inform future trials. This review informs readers on the current s
