in a new study done in the netherlands gastric banding (aka lap band) has been show to be inneffctive long term. For once the data needs little interpretation and is spelled out fairly openly in the beginning paragraphs:

(from Eating Disorders Review September/October 2010 Volume 21, Number 5)

“Adjustable gastric banding for obesity achieves only modest weight loss and even that benefit deteriorates over time, according to a report presented at the American Society of Metabolic and Bariatric Surgery in Las Vegas, NV in June. Edo Aarts, MD, of Rijnstate Hospital, Arnhem, The Netherlands, noted that 5 years after surgery, about 75% of his patients maintained a 25% excess weight loss. At 10 years, the success rate dropped to less than 33%. Surgeons at Rijnstate Hospital perform more than 800 gastric banding procedures annually, more than any other hospital in The Netherlands; more than 3,000 patients have had the procedure since it was introduced in the 1990s. Dr. Aarts and colleagues evaluated the long-term results of adjustable gastric banding in 201 patients who had undergone the procedure during the years 1995 to 2003; all had rigorous follow-up at 3-month intervals during the first year and then annually thereafter, and complete follow-up data was available for an average of 9.6 years.

Using excess weight loss of 25% or more to define treatment success, the Dutch surgeons found that about 80% of the patients retained weight loss during the first 3 years; after this there was a steady decline to 64% of patients at 5 years, and 20% at 10 years.”

Dieits dont work long term. period. the article goes on to talk about how “Control of diabetes, hypertension, and gastroesophageal reflux all deteriorated significantly over time. The incidence of new-onset diabetes and hypertension increased during follow-up, as did the proportion of patients requiring acid-suppression therapy.”

so event he medical resons for gastic banding or wls dont pan out long term. all you really have is a slower diet with more dramatic weight loss (and regain) in the long term.

 I ran across this lovely jewel today….apparently they have proved that people who are obese and undergo WLS, the are more likely to get kidney stones than their non WLS counterparts.   Even people with no previous stones or a family history of stones show a marked concentration of the ingredients for the stones.  The researchers found that the excretion of a material called oxalate in urine was significantly greater in the participants who had the surgical procedure than those who did not (47 percent, compared with 10.5 percent, respectively). In addition, the amount of a chemical called citrate in the urine was low in many gastric bypass patients in comparison to the obese nonsurgical group (32 percent to 5 percent). Oxalate is found in the majority of kidney stones, while citrate inhibits stone formation.

“Almost half of the patients who had undergone gastric bypass and did not have a history of kidney stones showed high urine oxalate and low urine citrate — factors that lead to kidney-stone formation,” said Dr. Naim Maalouf, assistant professor of internal medicine in the Charles and Jane Pak Center for Mineral Metabolism and Clinical Research and the study’s lead author.
