Effects of antecolic versus retrocolic duodenojejunostomy on delayed gastric emptying after pyloric preserving pancreaticoduodenectomy in patients with periampullary tumors.

Background/objective: Delayed gastric emptying (DGE) is one of the most frequent complications after pyloric preserving pancreaticoduodenectomy (PPPD). The aim of this study is to evaluate the effect of antecolic versus retrocolic reconstruction of gastroentric anastomosis on DGE after PPPD.

Methods: 30 patients with diagnosis of operable periampullary malignancies who candidate for PPPD, randomized in two equal groups.
