An antecolic Roux-en Y type reconstruction decreased delayed gastric emptying after pylorus-preserving pancreatoduodenectomy

The aim of this study was to identify a preferable procedure reducing the incidence of delayed gastric emptying (DGE) after pylorus-preserving pancreatoduodenectomy (PPPD). Data on 132 consecutive patients with pancreatobiliary disease, who underwent PPPD, were collected retrospectively. A retrocolic Billroth I type reconstruction (B-I group) and an antecolic Roux-en Y type reconstruction (R-Y group) were performed for 54 and 78 patients after PPPD, respectively. Clinical measures of DGE were compared between the two groups. The incidence of DGE was 81% in B-I group and 10% in R-Y group (P < 0.001). The type of reconstruction (P < 0.001), operative time (P=0.016), and postoperative complications (P=0.001) were significantly associated with DGE by univariate analysis. Only the type of reconstruction (P < 0.001) was identified as an independent factor, which was associated with DGE by multivariate analysis. An antecolic Roux-en Y type duodenojejunostomy could be a useful reconstruction method after PPPD to prevent the occurrence of DGE.
