Roux-en-Y Reconstruction Following Distal Gastrectomy Reduced Endoscopic Reflux Esophagitis in Older Adults: Propensity Score–Matching Analysis

Abstract

Objective This study aimed to examine the functional outcomes of Roux-en-Y (RY) and Billroth I (BI) reconstruction methods following distal gastrectomy in patients ages ≥75 years with gastric cancer. Summary of background data RY and BI reconstructions are commonly performed after distal gastrectomy. However, no study has compared the 2 procedures in older adults. Methods We identified older patients who underwent RY (n = 103) or BI (n = 71) reconstruction following distal gastrectomy from 2011 to 2018 in our database. Patients in the RY and BI groups were matched by propensity scores, and each group included 62 patients. We compared short-term surgical outcomes and clinical findings at 1 year postoperatively. Additionally, risk factors for endoscopic reflux esophagitis following distal gastrectomy were evaluated. Results Reflux esophagitis, bile reflux, and remnant gastritis were significantly less frequent in RY reconstruction than in BI reconstruction. Moreover, both BI reconstruction and preoperative hiatus hernias were independent risk factors for postoperative endoscopic reflux esophagitis. Although the incidence of postoperative surgical complications following RY and BI was similar, RY was found to cause delayed gastric emptying more frequently than BI. Conclusion RY reconstruction is a favorable procedure to prevent reflux esophagitis in older patients, particularly in those with hiatal hernia.
