Perioperative outcome of esophageal fundoplication for gastroesophageal reflux disease in obese and morbidly obese patients

摘要

Background To determine the perioperative safety of esophageal fundoplication for gastroesophageal reflux disease (GERD) in patients with body mass index (BMI) ≥35 kg/m2. Methods A retrospective review of 4,231 patients who underwent fundoplication for GERD from 2005 to 2009 was performed. Patients were identified via National Surgical Quality Improvement Program and grouped by BMI 35 versus BMI ≥ 35 kg/m2. Univariate analysis compared 30-day outcomes. Results Of the 4,231 patients, 3,496 (83%) had BMI 35 kg/m2 and 735 (17%) had BMI ≥ 35 kg/m2. Mean BMI for each cohort was 27.9 versus 39.1, respectively. Patients with BMI ≥ 35 kg/m2 had significantly longer operative times (129.7 vs 118 minutes, P .0001) and increased American Society of Anesthesiologists scores (2.43 vs 2.3, P =.001). The overall complication rate was 1.96%. No difference was demonstrated by BMI in complication rate or hospital length of stay. Increased American Society of Anesthesiologists score, diabetes, black race, longer operative time, and intraoperative transfusion significantly increased postoperative complication rates. Conclusions No increased risk is conferred to morbidly obese patients who undergo fundoplication for GERD management. This study identified independent patient risk factors for postoperative complication following esophageal fundoplication.
