Abstract

Introduction: Obese patients who fail primary surgical management of gastroesophageal reflux present a significant challenge. We reviewed our outcomes with reoperative reflux surgery in obese (body mass index (BMI) >30) and nonobese patients to identify predictors of failure and complications and evaluate whether reoperative fundoplication is the ideal solution for obese patients.

Methods: We conducted a retrospective review of consecutive patients undergoing reoperation for failed anti-reflux surgery between 1994 and 2013. Medical record review identified preoperative, intraoperative, and postoperative characteristics. Short- and long-term outcomes for obese and nonobese patients were compared using descriptive statistics and logistic regression.

Results: One hundred and nine interventions were identified in 95 patients. Clinical characteristics were similar between obese and nonobese patients. Eighty-eight (83.8%) patients underwent laparoscopic repair, 87 (79.8%) of whom had a Nissen fundoplication. Obese patients were more likely to fail via a slipped wrap (64.7 vs. 40.0%; p = 0.02). No differences were seen in short- or long-term symptomatic relief or major complications. In bivariate analysis, short-term outcomes were predicted by preoperative albumin <3.5 mg/dL (odds ratio (OR), 0.27 (confidence interval (CI), 0.08-0.96); p = 0.04) and laparoscopic conversion (OR, 0.19 (CI, 0.04-1.03); p = 0.05). Laparoscopic conversion was associated with major complications (OR, 7.33 (CI, 1.33-40.55); p = 0.02). BMI was a significant predictor for long-term outcome (p = 0.03) as a continuous variable in sensitivity analyses.

Conclusions: Obese patients with recurrence after failed anti-reflux operation may be safely treated with a repeat operation. Our data indicate no difference in outcomes for patients with BMI >30, underscoring the importance of preoperative discussion as to the best approach: reoperative fundoplication or a gastric bypass.
