Subtotal gastrectomy pancreaticoduodenectomy versus conventional pancreaticoduodenectomy in the incidence of delayed gastric emptying: single-center retrospective cohort study
Abstract
Abstract Background Delayed gastric emptying (DGE) is one of the most common complications after pancreaticoduodenectomy (PD). There is currently no widely accepted procedure for PD to reduce the incidence of DGE. Our institution attempts to perform subtotal gastrectomy in patients undergoing PD to reduce DGE. Here we aimed to evaluate the effectiveness and safety of PD with subtotal gastric resection. Methods Patients who underwent PD between January 2014 and December 2021 were reviewed. They were stratified by extent of gastrectomy into a conventional PD group (PD that resected approximately 1/3 of the distal stomach) and a subtotal gastrectomy PD group (PD that resected approximately 3/4 of the distal stomach), which were compared in terms of intraoperative and postoperative parameters. Result From January 2014 to December 2021, a total of 512 patients underwent PD in the Department of Hepatobiliary Surgery, Peking University People’s Hospital. Nineteen patients were excluded from this study due to benign disease. A total of 493 patients were included, with 378 in the conventional PD group and 115 in the subtotal gastrectomy PD group. Compared with the conventional PD group, the subtotal gastrectomy PD group had a lower incidence of DGE (8.7% vs. 17.7%, p = 0.019), and a shorter hospital stay. Multivariate analysis showed that conventional PD and higher body mass index were independent risk factors for grade B/C DGE. Conclusion This study showed that, compared with conventional PD, subtotal gastrectomy PD can reduce the incidence of DGE and shorten the length of hospital stay. At the same time, subtotal gastrectomy PD is comparable to conventional PD in terms of surgical safety. Furthermore, high BMI is an independent risk factor for postoperative DGE.
