OBJECTIVE: To compare, in a prospective, randomized, single-institution trial laparoscopic adjustable silicone gastric banding (LASGB) with laparoscopic vertical banded gastroplasty (LVBG) in morbidly obese patients. SUMMARY BACKGROUND DATA: LASGB is a simple and safe procedure, but some reports have suggested disappointing long-term results. Despite the recent widespread use of LASGB, there are no prospective nor randomized trials comparing LASGB with other laparoscopic procedures. METHODS: A total of 100 morbidly obese patients, with body mass index (BMI) 40 to 50 kg/m2, without compulsive eating, were randomized to either LASGB (n = 49) or LVBG (n = 51). Minimum follow-up was 2 years (mean 33.1 months). RESULTS: There were no deaths or conversions in either group. Mean operative time was 94.2 minutes in LVBGs and 65.4 in LASGBs (P < 0.05). Early morbidity rate was lower in LASGBs (6.1%) versus LVBGs (9.8%) (P = 0.754). Mean hospital stay was shorter in LASGBs versus LVBGs: 3.7 days versus 6.6 (P < 0.05). Late complications rate in LVBGs was 14% (7 of 50) and in LASGBs 32.7% (16 of 49) (P < 0.05). The most frequent complication was the slippage of the band (18%). Late reoperations rate in LVBGs was 0% (0 of 50) versus 24.5% (12 of 49) in LASGBs (P < 0.001). Excess weight loss in LVBGs was, at 2 years, 63.5% and, at 3 years, 58.9%; in LASGBs, excess weight loss, respectively, was 41.4% and 39%. BMI in LVBGs was, at 2 years, 29.7 kg/m2 and, at 3 years, 30.7 kg/m2; in LASGBs, BMI was 34.8 kg/m2 at 2 years and 35.7 kg/m2 at 3 years. According to Reinhold's classification, a residual excess weight <50% was achieved, at 2 years, in 74% of LVBG and 35% of LASGB (P < 0.001). CONCLUSIONS: This study demonstrates that, in patients with BMI 40 to 50 kg/m2, LASGB requires shorter operative time and hospital stay but LVBG is more effective in terms of late complications, reoperations, and weight loss.
