ABSTRACT
Objective:To investigate the preventive effect of postoperative pancreatic fistula by pedicled omentum wrapping pancreaticojejunostomy in pancreaticoduodenectomy.Methods:The clinical data of 78 patients who underwent pancreaticoduodenectomy in Songjiang Hospital Affiliated to Shanghai Jiao Tong University from September 2017 to August 2020 were retrospectively analyzed. Patients were divided into the modified pancreaticojejunostomy group (conventional approach group, n=43) and the pedicled omentum wrapping pancreaticojejunostomy group (omentum wrapping group, n=35) according to the surgical mode. Postoperative pancreatic fistula, postoperative abdominal bleeding, delayed gastric emptying and postoperative hospital stay were compared between the two groups. Results:Compared with the conventional approach group, the postoperative pancreatic fistula rate in omentum wrapping group was significantly reduced (2.9% vs 18.6%), and the difference was statistically different ( P=0.030); postoperative abdominal bleeding rate(0 vs 4.7%)and the delayed gastric emptying rate were significantly reduced (8.6% vs 25.6%), but both of them were not statistically different ( all P value>0.05); the length of postoperative hospital stay was significantly reduced [(11.3±2.9) days vs (12.8±3.5)days], and the difference was statistically different ( P=0.045). Conclusions:The pedicled omentum wrapping pancreaticojejunostomy was simple and convenient, which can significantly reduce the rate of postoperative pancreatic fistula. It can shorten the time of the length of hospital stay after surgery.
