"While the majority of morbidly obese patients who undergo gastric banding say they are generally satisfied years later almost  percent are saddled with major complications while about half have to have their bands removed a small new Belgian study reveals. The finding comes on the heels of a recent study out of the University of California San Francisco that suggested gastric bypass surgery is superior to alternative surgical methods such as gastric banding for promoting weight loss andor eliminating type  diabetes. The current observations stem from a research effort led by Dr. Jacques Himpens of the European School of Laparoscopic Surgery at the Saint Pierre University Hospital in Brussels whose team assessed the status of  patients that had undergone the procedure known as laparoscopic adjustable gastric banding LABG more than a decade prior to the study launch. Himpens and his colleagues outline their findings in the March  online issue and the July print issue of the Archives of Surgery. LAGB creates a small pouch by placing a constricting ring or band around the top portion of the stomach the smaller stomach size allows patients to feel full more quickly. Since its introduction in  the banding approach has become a popular alternative to RouxenY gastric bypass surgery which involves the literal stapling of the stomach in order to redirect food past part of the small intestine to instigate reduced food absorption as well as a quicker sensation of satiety. But LAGB surgery has come under criticism in the past for involving a relatively high risk for complications including wound infection and injury to the spleen and esophagus and a poor prognosis in terms of longterm quality of life. It is also been reported that LAGB patients are likely to regain much of their lost weight years down the road. To explore satisfaction levels and the longterm complication history of gastric banding in  Himpens and his team examined a pool of patients who had undergone the surgery between  and . The results  years or more later more than  percent of the banding patients said they were satisfied with their experience. On average excess weight loss had been maintained at a level approaching nearly  percent and quality of life appeared to be equal to that of patients who had not undergone the surgery. However  percent of the patients had experienced serious complications including abnormal pouch expansion  band erosion  and band infection . Another  percent experienced relatively minor complications. Almost  percent had to have the bands entirely removed while  percent needed to undergo subsequent surgery. The procedure appears to result in relatively poor longterm outcomes the researchers concluded. One in six of the patients ended up deciding to have a gastric bypass procedure and all of these patients demonstrated good outcomes following their subsequent surgery. Himpens said that patients should limit their expectations with respect to banding noting that all weightloss operations have a high failure rate. But he added that it is still defendable for surgeons to continue doing this. The high failure rate of the band gastroplasty in the long term is not that much worse than other procedures he noted. I therefore think patients will continue to ask for the procedure. But he cautioned that patients undergoing band surgery should do so knowing that they need to commit themselves to rigorous longterm followup. Meanwhile in a critique published alongside Himpens work Dr. Clifford W. Deveney a professor of surgery in the department of surgery at Oregon Health and Science University in Portland concluded that the current study does not shed a favorable light on the use of LAGB. The band has a spotty history Deveney said. Some groups have very good results with  to  percent weight loss. But other groups have either poor weight loss or complications or both. So I think he continued that the patient should be made aware of these facts and also that the weight loss is going to be less with the band than with a gastric bypass. And that itll take longer to achieve the weight loss because with gastric bypass most of the weight loss occurs over the first year while with a band it takes five to six years. Its also easier to cheat on the band he added. You can eat around the band and render it ineffective if youre not disciplined in following a healthy diet. With gastric bypass thats not as much of an issue. But all this is not to say that I think we shouldnt be doing bands. Its just not as good as bypass. Dr. Mitchell S. Roslin chief of bariatric surgery at Northern Westchester Hospital in Mount Kisco N.Y. said he was not surprised by the findings. I always tell my patients that bands are like going a diet with a seatbelt he said. And that theres bound to be a  percent extraction rate of these bands per year that theyre in. Which actually comes to about the same percent of band removals these researchers observed among their patients. I think the problem with the bands is simply that having a fixed obstruction underneath your esophagus is not a natural occurrence Roslin noted. And also these bands make it more difficult to eat but they do not make every patient less hungry. So theres a big variability in treatment effect. Youll see patients who do great and patients who dont. Almost like a camel with two humps. So bands are easy to sell and very heavily marketed he added. But for many patients there are better options.
