Lap banding safe and effective long-term strategy for management of obesity

Laparoscopic adjustable gastric banding - lap banding - is a safe and effective long-term strategy for managing obesity, according to the findings of a landmark 15-year follow-up study of patients treated in Australia.

The follow-up study, the longest and most comprehensive yet reported, was published in the Annals of Surgery, and found a significant number of lap band patients maintained an average weight loss of 26 kilograms for more than a decade after their procedure.

Professor Paul O'Brien and colleagues from the Centre for Obesity Research and Education (CORE) at Monash University in Melbourne analysed the results in 3,227 patients who had gastric banding between 1994, when the procedure was first introduced, and 2011. The patients in the study were averaged at 47 years of age and 78 per cent were women.

Of those patients, 714 had surgery at least 10 years ago and, on average, had maintained a weight loss of 26 kilograms, or almost half of their excess weight.

The weight loss results were similar for the 54 patients in the study who had undergone treatment at least 15 years ago.

"These results show that when you have a significant problem with obesity, a long-term solution is available," Professor O'Brien said.

"This surgery is safe and effective, and it has lasting benefits. Substantial weight loss can change the lives of people who are obese - they can be healthier and live longer."

Professor O'Brien said there were also important ramifications for the control of type 2 diabetes, which was strongly associated with being overweight.

"In obese patients with type 2 diabetes, weight loss after gastric banding can lead to effective control of blood sugar levels without the need for medication in about three-quarters of cases," Professor O'Brien said.

The patients included in the study had followed the rules of their treating team regarding eating, exercise and activity and committed to returning permanently to the aftercare program.

All the surgery was performed by Professor O'Brien, an international pioneer of the technique, and Associate Professor Wendy Brown, President of the Obesity Surgery Society of Australia and New Zealand (OSSANZ).

There were no deaths associated with the surgery or with any later operations that were needed in about half of the patients. About one in 20 patients had the band removed during the study period.
