Abstract
BACKGROUND: Although bariatric surgery is a safe and effective treatment for morbid obesity, long-term reoperation remains a significant source of morbidity and mortality for the patient.
METHODS: We performed a retrospective analysis of all patients undergoing laparoscopic gastric bypass (LGBP) or laparoscopic sleeve gastrectomy (LSG) surgeries at our institution between 2009 and 2013. Main outcome of interest was reoperation rate up to current date. Final logistic regression model included age, gender, BMI at time of operation, race (Caucasian vs African American), surgery time, length of stay, history of diabetes, history of gastroesophageal reflux disease (GERD), type of surgery, and readmission.
RESULTS: A total of 533 patients underwent either LGBP or LSG surgery between 2009 and 2013. Overall reoperation rate was 9.0% and mean follow-up was 43.9 months (median 45). When stratified by race, preoperative GERD in Caucasians was associated with a significant 2.2-fold increased risk of reoperation (OR 2.2, 95% CI 1.0–4.8, P = .043). GERD in African Americans had a small nonsignificant increased risk. Other significant predictors included length of stay and readmission (OR 2.1, P = 0.029; OR 5.0, P < 0.000).
CONCLUSION: Preoperative GERD in Caucasian bariatric patients is associated with a higher risk of reoperation. Lengthy hospital stay and readmission within 30 days of laparoscopic bariatric surgery are independent predictors of higher reoperation rates.
