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 equals; 49) or LVBG (n equals; 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) (Pequals; 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/m2and, at 3 years, 30.7 kg/m2; in LASGBs, BMI was 34.8 kg/m2at 2 years and 35.7 kg/m2at 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.
