BACKGROUND:Antecolic reconstruction after pylorus-preserving pancreatoduodenectomy (PPPD) has been reported to decrease the incidence of delayed gastric emptying (DGE), which is one of the main postoperative complications. Subtotal stomach-preserving PD (SSPPD), in which duodenum and pylorus ring were removed, was introduced for the purpose of decreasing the incidence of DGE. This prospective randomized control study was performed to assess whether antecolic reconstruction decreases the incidence of DGE compared with retrocolic reconstruction after SSPPD. MATERIALS AND METHODS:Forty-six patients were enrolled in this trial between May 2007 and June 2010. Twenty-two and 24 patients were randomized for the retrocolic and antecolic groups, respectively. The primary endpoint was DGE incidence. RESULTS: The overall incidence of DGE in the retrocolic group was significantly higher than that in the antecolic group (50% versus 20.8%, P=0.0364). In particular, this difference was most striking in the incidence of DGE grade B/C (27.3% versus 4.2%, P=0.0234). Furthermore, patients in the retrocolic group required significantly longer time to full resumption of diet compared with the antecolic group. No significant difference was observed in other postoperative complications between the two groups. CONCLUSION: Antecolic reconstruction, and not retrocolic reconstruction, decreases DGE incidence after SSPPD.
