LAGB is a technique increasingly used in the USA. The aim of this study is to analyze the 5-year outcome in terms of weight loss and complications.


We reviewed our prospective electronic database for all patients undergoing LAGB between 2002 and 2007. We assessed weight progression, complications, and reoperations.


We performed 199 cases during this period (70.4% females). Mean age was 37.8 ± 12.4 years. Preoperative body mass index (BMI) was 36.0 ± 3.8 kg/m(2). Preoperative comorbidities were dyslipidemia in 52.3%, insulin resistance in 30.7%, arterial hypertension in 24.6%, and type 2 diabetes in 5.5%. There were no conversions to open technique. Early complications were observed in two patients (1%): one hemoperitoneum and one ileitis. Mortality was 0%. Late complication rate was 33.6% (18.0% related to the band). Reoperation was required in 40 patients (20.1%). Laparoscopic repositioning was done in seven patients, and port/reservoir revision was done in five patients. Band removal was required in 28 patients, due to inadequate weight loss in 9, slippage in 9, gastric erosion in 1, bowel obstruction in 1, acute stomach dilatation in 1, and food intolerance in 7. Twenty of these patients underwent revisional surgery: sleeve gastrectomy in 12 and laparoscopic Roux-en-Y gastric bypass in 8 cases. Unrelated band complication was seen in 15.6%, mainly due to anemia (7.5%), alopecia (4.5%), and cholelithiasis (3.5%). With a median follow-up of 48 months (1-72 months), 75, 60, and 95% of patients were available for follow-up at 1, 3, and 5 years, respectively. Mean percent excess weight loss (%EWL) at 1, 3, and 5 years was 58.8 ± 30.0%, 56.8 ± 35.0%, and 58.4 ± 46.6%, respectively. However, failure rate (%EWL <50%) at 1, 3, and 5 years was 40.4, 43.5, and 46.3%, respectively.


LAGB has low perioperative morbidity. However, its late complications are significant, and inadequate weight loss can be as high as 46.3% after 5 years.
