Abstract

Background: Delayed gastric emptying (DGE) is a common complication after pancreaticoduodenectomy (PD), but a method to prevent DGE has not been established. This study aims to demonstrate a novel technique utilizing a lengthened efferent limb in Billroth-II (B-II) reconstruction during PD and to evaluate the impact of the longer efferent limb on DGE occurrence.

Methods: Patients who underwent PD with B-II reconstruction were divided into two groups: PDs with lengthened (50-60 cm) efferent limb (L group) and standard length (0-30 cm) efferent limb (S group). Postoperative outcomes were compared. DGE was defined and graded according to the International Study Group of Pancreatic Surgery criteria.

Results: Among 283 consecutive patients who underwent PD from 2002 to 2021, 206 patients were included in this study. Patients who underwent Roux-en-Y reconstruction (n = 77) were excluded. Compared with the S group, the L group included older patients and those who underwent PD after 2016 (p = 0.025, < 0.001, respectively). D2 lymphadenectomy, antecolic route reconstruction, and Braun enteroenterostomy were performed more frequently in the L group (p = 0.040, < 0.001, < 0.001, respectively). The rate of DGE was significantly decreased to 6% in the L group, compared with 16% in the S group (p = 0.027), which might lead to a shorter hospital stay in the L group (p < 0.001). Multivariable analysis identified two factors as independent predictors for DGE: intraabdominal abscess [odds ratio (OR) 5.530, p = 0.008] and standard efferent limb length (OR 2.969, p = 0.047).

Conclusion: A lengthened efferent limb in Braun enteroenterostomy could reduce DGE after PD.
