摘要
Recent advances in surgical techniques and perioperative management have markedly reduced operative morbidity after distal pancreatectomy(DP).However,some questions remain regarding the protocol for the perioperative management of DP,in particular,with regard to the development of pancreatic fistula(PF).A review of DP was therefore conducted in order to standardize the management of patients for a favorable outcome.Overall,operative technique and perioperative management emerged as two critical factors contributing to favorable outcome in DP patients.As for the operative method,surgical and closure techniques exhibited differences in outcome.Laparoscopic DP generally yields more favorable perioperative outcomes compared to open DP,and is applicable for benign tumors and some ductal carcinomas of the pancreas.Robotic DP is also available for safe pancreatic surgery.En bloc celiac axis resection offers a high R0 resection rate and potentially allows for some local control in the case of advanced pancreatic cancer.Following resection,staple closure was not found to reduce the rate of PF when compared to hand-sewn closure.In addition,ultrasonic dissection devices,fibrin glue sealing,and staple closure with mesh reinforcement were shown to significantly reduce PF,although there was some bias in these studies.In perioperative management,both preoperative and postoperative treatment affected outcome.First,preoperative endoscopic pancreatic stenting may be an effective prophylactic measure against fistula development following DP in selected patients.Second,in postoperative management,a multifactorial approach including prophylactic antibiotics improved high surgical site infection rates following complex hepato-pancreatobiliary surgery.Furthermore,although conflicting results have been reported,somatostatin analogues should be administered selectively to patients considered to have a high risk for PF.Finally,careful drain management also facilitates a favorable outcome in patients with PF after DP.The results of the rev
