Home » Why is Adjustable Gastric Band surgery no longer reccomened?
Here are some of the scientific studies that led us to the conclusion that adjustable gastric banding surgery can no longer be recommended.
Annals of Surgery Vol. 260 Issue 5 pages 893-899, 2013.
These surgeons found that the RY gastric bypass was far superior to the adjustable gastric band in improving the liver damage (including cirrhosis) caused by severe obesity 5 years after the surgery. Liver disease known as Non Alcoholic Fatty Liver Disease (NAFLD, figure D) is present in 86% of patients with severe obesity. When left untreated, it can damage the liver and result in cirrhosis (figure A) and the need for liver transplantation to save a patient’s life.

These bariatric surgeons in Italy studied patients that agreed to have either a laparoscopic gastric bypass or laparoscopic gastric band based on a head/tails coin toss (thus the term “randomized trial”) in 2003. Ten years after the study, those in the gastric bypass group lost a greater percentage of the excess weight they carried (69%) compared to the band patients (46%). They also observed that 40% of the band patients required more surgery over the ensuing 10 years.

A total of 3,227 patients were treated by laparoscopic adjustable gastric band placement between September 1994 and December 2011. Seven hundred fourteen patients had completed at least 10 years of follow-up. The study found a 47% of excess weight loss at 15 years. A high number of revision procedures were performed-proximal pouch enlargement (26%), erosion (3.4%), and port and tubing problems (21%).

A total of 151 consecutive patients who had had adjustable gastric band surgery between January 1, 1994, and December 31, 1997, were contacted for evaluation at the University obesity center in Brussels, Belgium. Twenty-two percent of patients experienced minor complications, and 39% experienced major complications (28% experienced band erosion). Seventeen percent of patients had their procedure switched to laparoscopic Roux-en-Y gastric bypass. The 36 patients (51.4%) who still had their band, lost 48% of their excess weight. These results show that laparoscopic band surgery gives at most 50% chance of no complications with at best 48% excess weight lost.

The salient message of the 2011 assessment is that patients are abandoning adjustable gastric banding and are choosing sleeve gastrectomy which has gone from 7% in 2008 to 35% in 2012. Adjustable gastric banding has fallen from 43% in 2008 to 15% in 2012. By the middle of next year banding requests are predicted to fall to less than 5%.
The salient message of the 2011 assessment is that SG (0.0% in 2008) has markedly increased in prevalence.
The graph below shows the laparoscopic bariatric surgical procedure selected by our patients since 2006.
Note the decline in gastric banding requests, whereas the requests for vertical sleeve gastrectomy are increasing.
Most of our patients chose the gastric bypass as this is our specialty.
Allergan Inc. (the current distributor of the Lap BandR adjustable gastric banding device) announced that it has struck a deal to sell its failed obesity treatment business. The adjustable gastric banding device has been criticized as less effective and slower to produce results than some other weight-loss procedures that have grown in popularity in recent years, such as the sleeve gastrectomy, which removes a large portion of the stomach to curb food intake. Another competitor is the Roux-en-Y gastric bypass, which shrinks the stomach and reroutes the digestive tract.
Lap-Band never lived up to Allergan’s hopes. Sales dropped sharply over several quarters, and it was hit by negative publicity after patient deaths. The Irvine-based pharmaceutical and medical device company agreed to sell the obesity unit to Apollo Endosurgery Inc. of Austin, Texas, for about~ 75 million$ (origanal cost in billions of $).
