Background: From 1993 to 1999, 172 patients underwent adjustable silicone gastric banding (ASGB) or laparoscopic adjustable silicone gastric banding (LASGB). In 109 patients the adjustable band was placed via laparoscopy; in the other patients it was placed via laparotomy (prelaparoscopic era, conversions from other bariatric operations, conversions for laparoscopic failure). The conversion rate from laparoscopy to laparotomy was 9.3%, occurring in the early part of our experience. Methods: Mean age was 37.9 years, weight 135 ± 14.8 kg (82-218) and BMI 46.3 ± 5.4 (35.1-69.5). All patients had multiple band adjustments, temporary antisecretive, electrolyte and vitamin therapy, and follow-up per routine. Results: Weight loss at 3 years was 30.2%; mean percent loss of excess weight was 62.5%.There was no mortality.The most important technical complications were: gastric pouch dilatation that required band replacement or removal (5.8 %); mild gastric pouch dilatation reversible with adequate dietary and pharmacological treatment (4.6%); intraoperative gastric perforation (2.3%); band migration (0.6%).The band was removed in 2.3%, with conversion to another bariatric procedure in 1.1%. Conclusions: Results have been satisfactory thus far.
