Mean fourteen-year, 100% follow-up of laparoscopic adjustable gastric banding for morbid obesity.Surg Obes Relat Dis. 2013 Sep-Oct; 9(5):753-7.SO
Many studies of short-term to mid-term outcomes after laparoscopic adjustable gastric banding (LAGB) have been published, but reliable long-term outcome reports with a minimum follow up ≥ 10 years in a sufficient number of included patients are still scarce. The objective of this study was to evaluate the long-term results after LAGB.
Sixty consecutive patients (44 women, 16 men) were treated for morbid obesity by LAGB between 1996 and 1999. Median age of the patients at the time of operation was 45 years (range 21-64). Median preoperative body mass index (BMI, kg/m(2)) was 45 (range 35-55). All patients were asked to adhere to a strict follow-up program. Patients' BMI and percentage excess weight loss (%EWL) were calculated in the hospital's database for bariatric patients, and excess weight was taken as the weight in kilograms above the weight at BMI of 25 kg/m(2).
Complete data on all 60 patients could be assessed; thus, the overall rate of follow-up was 100%. After a median (range) follow-up of 14.1 years (13.2-16.8 years), the mean BMI (SD) dropped from 45 (5) to 36 (6) kg/m(2), with a mean (SD) EWL of 49% (29). At 15 years of follow-up, 29 (48%) bands have been removed, and 38 (63%) reoperations have been performed in 29 (48%) patients. Almost 70% received further treatment for their morbid obesity after band removal. Of those patients with the band still in place at 14 years, 40% had more than 50% EWL and 20% had less than 25% EWL. There was no mortality related to the primary or revisional operations, but 2 patients died of unrelated causes.
Mean %EWL after LAGB after more than 14 years was fairly good-49%. However, a reoperation rate of more than 60% in 48% of the patients and a band removal rate of almost 50% may indicate that LAGB cannot be recommended as a primary procedure to the general morbidly obese population.
