Reconstruction by Pancreaticojejunostomy Versus Pancreaticogastrostomy Following Pancreatectomy

Abstract

In Brief Objective: To compare the results of pancreaticogastrostomy versus pancreaticojejunostomy following pancreaticoduodenectomy in a prospective and randomized setting. Summary Background Data: While several techniques have been proposed for reconstructing pancreatico-digestive continuity, only a limited number of randomized studies have been carried out. Methods: A total of 151 patients undergoing pancreaticoduodenectomy with soft residual tissue were randomized to receive either pancreaticogastrostomy (group PG) or end-to-side pancreaticojejunostomy (group PJ). Results: The 2 treatment groups showed no differences in vital statistics or underlying disease, mean duration of surgery, and need for intraoperative blood transfusion. Overall, the incidence of surgical complications was 34% (29% in PG, 39% in PJ, P = not significant). Patients receiving PG showed a significantly lower rate of multiple surgical complications (P = 0.002). Pancreatic fistula was the most frequent complication, occurring in 14.5% of patients (13% in PG and 16% in PJ, P = not significant). Five patients in each treatment arm required a second surgical intervention; the postoperative mortality rate was 0.6%. PG was favored over PJ due to significant differences in postoperative collections (P = 0.01), delayed gastric emptying (P = 0.03), and biliary fistula (P = 0.01). The mean postoperative hospitalization period stay was comparable in both groups. Conclusions: When compared with PJ, PG did not show any significant differences in the overall postoperative complication rate or incidence of pancreatic fistula. However, biliary fistula, postoperative collections and delayed gastric emptying are significantly reduced in patients treated by PG. In addition, pancreaticogastrostomy is associated with a significantly lower frequency of multiple surgical complications. Following pancreaticoduodenectomy, similar incidence of overall surgical complications and pancreatic fistula were reported after reconstruction by either pancreaticogastrostomy or pancreaticojejunostomy in a randomized, prospective clinical trial. Moreover, pancreaticogastrostomy is associated with a significantly lower rate of multiple abdominal complications, biliary fistula, postoperative collections, and delayed gastric emptying.
