Trial of Omental Roll-up Technique on Pancreato-jejunostomy Anastomosis for Reducing Perioperative Complication in Patients Undergoing Pancreatoduodenectomy

Despite the fact that pancreatoduodenectomy is the standard treatment of malignant tumor at periampullary area, the morbidity and mortality rate with intra-abdominal collection, post pancreatectomy hemorrhage, and delayed gastric emptying, is still high at approximately 50-60%. The causes of these complications usually come from post-operative pancreatic fistula. Nowadays, several methods have been reported to reduce the incidence of pancreatic fistula after undergoing pancreatoduodenectomy, such as pancreatic stenting, the use of intravenous somatostatin, the use of sealant material and wrapping anastomosis by soft tissue. Wrapping pancreato-jejunal anastomosis with omentum is not a complicate procedure and requires no extra treatment expenses of the patient. It has been reported this technique has been applied in the non-randomized controlled trials and their data have significantly shown that the technique could reduce pancreatic fistula rate. Therefore, the researchers want to conduct an RCT study to compare complication rates between omental roll-up pancreato-jejunal anastomosis and non-omental roll-up groups.
