title: Clinical trials to reduce pancreatic fistula after pancreatic surgery-review of randomized controlled trials.
abstract: Pancreatic fistula is one of severe postoperative complications that occur after pancreatic surgery, such as pancreaticoduodenectomy (PD) and distal pancreatectomy (DP). Because pancreatic fistula is associated with a higher incidence of life-threatening complications. In order to evaluate procedure or postoperative management to reduce pancreatic fistula after pancreatic surgery, we summarized some randomized controlled trials (RCTs) regarding pancreaticoenterostomy during PD, pancreatic duct stent during PD, procedure to resect pancreatic parenchyma during DP, and somatostatin and somatostatin analogues after pancreatic surgery. At first, we reviewed nine RCTs to compare pancreaticogastrostomy (PG) with pancreaticojejunostomy (PJ) during PD. Next, we reviewed five RCTs, to evaluate the impact of pancreatic duct stent during PD. Regarding DP, we reviewed six RCTs to evaluate appropriate procedure to reduce pancreatic fistula after DP. Finally, we reviewed eight RCTs to evaluate the impact of somatostatin and somatostatin analogues after pancreatic surgery to reduce pancreatic fistula. The best way to prevent pancreatic fistula after pancreatic surgery remains still controversial. However, several RCTs clarify a useful procedure to reduce in reducing the incidence of pancreatic fistula after pancreatic surgery. Further RCTs to study innovative approaches remain a high priority for pancreatic surgeons to prevent pancreatic fistula after pancreatic surgery.
