Tailoring Bariatric Surgery: Sleeve Gastrectomy, Roux-en-Y Gastric Bypass and Biliopancreatic Diversion with Duodenal Switch.
BACKGROUND: A need exists to select the most appropriate bariatric operation for a particular patient. One-year data comparing sleeve gastrectomy (SG) to Roux-en-Y gastric bypass (RYGB) and biliopancreatic diversion with duodenal switch (BPD/DS) are sparse. METHODS: The Bariatric Outcomes Longitudinal Database was queried from June 2007 to September 2011 for 30-day and 1-year adverse events, and 1-year weight loss and comorbidity resolution. Propensity scores with inverse probability weighting were used to match for age, gender, body mass index (BMI), ethnicity, and select comorbidities. Multivariate linear and logistic regressions estimated differences and odds ratios (ORs), respectively, for each pairwise bariatric operation comparison. RESULTS: Among 73,702 subjects, 5942 patients underwent SG, 66,324 patients underwent RYGB, and 1436 patients underwent BPD/DS. Compared with SG, decrease in BMI units was greater by 5.3 for BPD/DS and by 2.2 U for RYGB at 1 year. Resolution of gastroesophageal reflux disease (GERD) was best for RYGB (OR = 1.88, 95% confidence interval [CI]: 1.73-2.03) and still good for BPD/DS (OR = 1.57, 95% CI: 1.29-1.90). Hypertension and diabetes mellitus (DM) resolution were better after BPD/DS (OR = 2.12, 95% CI: 1.83-1.64, and OR = 2.53, 95% CI: 2.13-3.00, respectively) and for RYGB were (OR = 1.54, 95% CI: 44-1.64 and OR = 1.63, 95% CI: 1.51-1.75, respectively). Odds of serious adverse events at 1 year were: RYGB, OR = 1.70, 95% CI: 1.45-2.00; BPD/DS, OR = 4.31, 95% CI: 3.06-6.07. CONCLUSIONS: Using SG as reference, RYGB was associated with highest resolution of GERD, whereas BPD/DS was associated with highest resolution of DM and hypertension. These findings can guide decision making regarding choice of bariatric operation.
