Postoperative reflux esophagitis in laparoscopic distal gastrectomy with Billroth‐I reconstruction for gastric cancer: Nutritional effect and preoperative risk factors

Abstract

AbstractIntroductionPostoperative reflux esophagitis represents a major complication of laparoscopic distal gastrectomy (LDG) with Billroth‐I reconstruction (LDGBI). This study aimed to evaluate the nutritional effect and preoperative risk factors of postoperative reflux esophagitis in patients undergoing LDGBI for gastric cancer.MethodsWe retrospectively analyzed data of patients with (reflux [+]) and without (reflux [−]) postoperative reflux esophagitis who underwent LDGBI in our institution. Patient backgrounds, surgical outcomes, and perioperative nutritional status were compared. Preoperative risk factors for postoperative reflux esophagitis were also evaluated.ResultsBetween January 2009 and December 2016, 242 patients underwent LDG for gastric cancer. Of these, 218 underwent Billroth‐I reconstruction. Seventy‐three patients were excluded because of nutritional or oncological reasons. Finally, 23 patients were enrolled as the reflux (+) group and 122 as the reflux (−) group. Although the preoperative/postoperative bodyweight ratio and albumin and hemoglobin values plateaued beyond 6 months postoperatively in the reflux (−) group, these parameters continued to decrease beyond this time in the reflux (+) group. The mean ± SD bodyweight ratios at 3 years postoperatively were 82.83% ± 9.73% and 89.45% ± 8.04% for the reflux (+) and reflux (−) group, respectively (P = .0006). Multivariate analysis revealed that postoperative reflux esophagitis was associated with postoperative body weight loss. Another multivariate analysis revealed preoperative hiatal hernia as an independent predictive factor for postoperative reflux esophagitis.ConclusionThe risk of reflux esophagitis after LDGBI in patients with hiatal hernia should be considered when deciding therapeutic approaches for such patients.
