Laparoscopic Adjustable Silicone Gastric Banding vs Laparoscopic Vertical Banded Gastroplasty in Morbidly Obese Patients: Long-Term Results of a Prospective Randomized Controlled Clinical Trial
Background Aim of the study is to present long-term results of a prospect i ve r and omized single-institution clinical trial comparing laparoscopic adjustable silicone gastric b and ing ( LASGB ) with laparoscopic vertical b and ed gastroplasty ( LVBG )  in morbid obesity . Methods A total of 100 morbidly obese patients ( body mass index 40 to 50 kg/m2 ) were r and omized to LASGB ( n = 49 ) or LVBG ( n = 51 ) and followed up for a minimum of 7 years . Results Mean operative time was 65.4 min in LASGBs and 94.2 min in LVBGs ( p < 0.05 ) ; mean hospital stay was 3.7 and 6.6 days , respectively ( p < 0.05 ) . Late complication rates were 36.7 % in LASGBs vs 15.7 % in LVBGs at 3 years ( p < 0.05 ) , 46.9 % vs 43.1 % at 5 years ( NS ) , and 55.1 % vs 47.1 % at 7 years ( NS ) . Late reoperation rates were 28.6 % in LASGBs and 2.0 % in LVBGs at 3 years ( p < 0.001 ) , 38.8 % and 2.0 % at 5 years ( p < 0.001 ) , and 46.9 % and 7.8 % at 7 years ( p < 0.001 ) . Excess weight loss in LASGBs was 41.8 % at 3 years , 33.2 % at 5 years , and 29.9 % at 7 years ; excess weight loss in LVBGs was 60.9 % , 57 % , and 53.1 % , respectively ( p < 0.05 ) . Conclusions This study demonstrates that in a carefully selected group of patients , LVBG is significantly more effective than LASGB in terms of late complications , late reoperations , and long-term results on weight loss
