To evaluate the safety and efficacy of modified pancreaticobiliary anastomosis without pancreaticojejunostomy for jejunal mucosa anastomosis.

A retrospective analysis of 120 patients who underwent pancreaticoduodenectomy from July 2008 to July 2018 was conducted. The patients were divided into the traditional group (n=60) and the improved group (n=60) according to the different surgical procedure. The conventional pancreaticoduodenectomy was performed in the traditional group. The modified jejunal mucosal anastomosis was performed in the modified group. SPSS20.0 statistical software was selected to analyze. The perioperative condition was compared with mean deviation (±s). Independent t test was used. Safety index was checked by chi square. P<0.05 was statistically significant.

The operation time, hospitalization time, eating time, hospitalization expenses, ambulation time, first exhaust time, first defecation time, bowel sounds recovery time, pancreaticojejunal mucosa anastomosis time and postoperative pancreatic fistula A, B, C rate in the improved group were better than those in the traditional group (P<0.05). The incidence of complications was 61.7% in the traditional group and 15.0% in the improved group. The difference was statistically significant (χ²=27.638, P<0.01).

The modified pancreatic jejunojejunostomy has advantages with short operation time, low incidence of other complications, such as pancreatic fistula, good recovery.
