Long-term outcome after laparoscopic adjustable gastric banding for morbid obesity.

This study was performed to determine the long-term consequences of laparoscopic gastric banding on weight loss, body image, and life quality in morbidly obese patients. After a minimum follow-up of 9 years (mean follow-up 10 years; range 9-12 years) several questionnaires concerning weight loss, body image, and life quality were mailed to 180 morbidly obese patients following laparoscopic adjustable gastric banding. One hundred and twelve (62%) patients (92 females, 20 males) completed and returned the questionnaires. Of the entire sample, 73 (64.9%) patients still had the first band, 17 (15.3%) a second band, and in 22 (19.8%) probands the band had been removed for various reasons. Average weight loss, calculated as change in body mass index, was 13.9 kg/m². Average excess weight loss (EWL) was 30.6%. A total of 10% patients accounted for >50% of EWL. Half of the probands were completely satisfied with their weight loss and about half had reached their planned weight. Lowest post-operative weight was reached at different times, in nearly half of the probands after 2 years, in one-fourth after 4-5 years, and in about 20% at a later time. More than 90% of the probands experienced longer interruptions in weight loss; about half knew why. The findings indicate that overall quality of life was rated good to excellent by two-thirds of the probands, and fair to poor by one-third. A close correlation was seen between extent of weight loss and quality of life and body image. Despite some limitations, laparoscopic adjustable gastric banding is an effective and safe long-term surgical treatment for a majority of morbidly obese individuals, resulting in long-term weight loss and health-related quality of life. However, there is also a minority of morbidly obese subjects who do not benefit enough from this kind of bariatric surgery. Future research should investigate what kind of bariatric surgery is best for the particular obese individual in order to minimize unsatisfying post-operative results.
