摘要
BACKGROUND: Surgery remains the most effective intervention for obesity and its comorbidities. However, the long-term efficacy of bariatric procedures is rarely reported. This study addresses operative trends, efficiency, and long-term outcomes from a large bariatric program. STUDY DESIGN: Data were prospectively collected on 3,460 patients undergoing 3,503 operations from January 2004 to March 2013. Primary procedures included Roux-en-Y gastric bypass (RY; n = 2,966), adjustable band (AB; n = 352), and sleeve gastrectomy (SG; n = 118). There were 67 revisional procedures (RP). Mean operative time, hospital length of stay, major 30-day morbidity/mortality, follow-up compliance, and weight loss per procedure at follow-up were recorded. RESULTS: Mean operative times decreased to the following: RY, 53 minutes; AB, 35 minutes; SG, 46 minutes; and RP, 71 minutes. Mean length of stay was reduced to the following: RY, 1.53 days; AB, 0.97 days; SG, 2.12 days; and RP, 2.68 days. Major complications were mortality, 0.09%; leak, 0.51%; bleed, 2.37%; pneumonia, 0.63%; venous thromboembolism, 0.40%; and reoperation, 2.34%. The complication rate was lowest for AB and highest for SG (p < 0.05). Adjustable band was the initial procedure in 73% of cases requiring RP. Follow-up compliance was 93% at 1 year, 79% at 3 years, 71% at 5 years, and 33% at 9 years. Adjustable band offered significant weight loss at 1 and 3 years (p < 0.0001), but less than RY or SG (p < 0.0001). Excess weight loss was not significantly different between RY and SG at 1 year. Significant weight loss with RY persisted at 7 to 9 years (p < 0.0001). CONCLUSIONS: Our bariatric program experienced an increase in SG and RP and a decrease in AB. Optimization of care reduced operative time and length of stay. All procedures achieved significant weight loss in the first year. Adjusted band had the lowest morbidity, but inferior weight loss and greater need for revision. Long-term weight-loss data are only available for RY.
