11-Year Experience with Laparoscopic Adjustable Gastric Banding for Morbid Obesity—What Happened to the First 123 Patients?
Background Few long-term studies regarding the outcome of  laparoscopic adjustable gastric b and ing for morbid obesity have so far been published . We report our 11-year experience with the technique by looking closely at the first 123 patients that have at least 5 years ( mean 86 months ) of follow-up . Methods Data have been collected prospect ively among 280 patients operated since March 1996 . Until March 2002 ( minimum 5-year follow-up ) , 123 patients have been operated laparoscopically with the Swedish b and .  We report major late complications , reoperations , excess weight losses ( EWL ) and failure rates among these patients , with a mean ( range ) follow-up time of 86 months ( 60–132 ) . EWL < 25 % or major reoperation was considered as a failure . EWL > 50 % was considered a success . Results Mean ( range ) age of the patients ( male/female ratio 31:92 ) was 43 years ( 21–44 ) . Mean ( range ) preoperative weight was 130 kg ( 92–191 ) . Mean ( range ) preoperative body mass index was 49.28 kg/m2 ( 35.01–66.60 ) . Patients lost to follow-up was nearly 20 % at 5 years and 30 % at 8 years . Major late complications ( including b and erosions 3.3 % , slippage 6.5 % , leakage 9.8 % ) leading to major reoperation occurred in 30 patients ( 24.4 % ) . Nearly 40 % of the reoperations was performed during the third year after the operation . The mean EWL at 7 years was 56 % in patients with the b and in place , but 46 % in all patients . The failure rates increased from about 15 % during years 1 to 3 to nearly 40 % during years 8 and 9 . The success rate declined from nearly 60 % at 3 years to 35 % at 8 and 9 years . Conclusions Complications requiring reoperations are common during the third year after the operation , and almost 25 % of the patients will need at least one reoperation . Mean EWL in all patients does not exceed 50 % in 7 years or 40 % in 9 years and failure rates increase with time , up to 40 % at 9 years
