Background/Aims: This study investigated the impact of Braun anastomosis on the incidence of delayed gastric emptying (DGE) and on the intragastric bile reflux after pancreatoduodenectomy with Child reconstruction. Methods: Sixty-eight patients who underwent subtotal stomach-preserving pancreatoduodenectomy were included. Patients were randomly assigned to a group with or without Braun anastomosis intraoperatively. Twenty-four-hour intragastric bilirubin monitoring was performed to investigate the extent of intragastric bile reflux after surgery. The incidence of DGE and other complications was also monitored. Results: There were no differences between the non-Braun and Braun groups in terms of patient characteristics. The incidence rate of DGE was 29.4% (n = 10/34) in the non-Braun group and 20.6% (n = 7/34) in the Braun group (p = 0.401). Forty-six of the 68 patients consented to intragastric bilirubin monitoring. The fraction time of intragastric bilirubin reflux was comparable between the 2 groups. Although the fraction time of intragastric bilirubin reflux had no impact on the incidence of DGE, the incidence of pancreatic fistula was significantly higher in patients with DGE than those without DGE (47.1 vs. 21.6%, p = 0.043). Conclusion: The addition of Braun anastomosis after pancreatoduodenectomy did not effectively reduce the intragastric bile reflux and had minor impact in reducing the incidence of DGE.
