No, Wasa, your forum is full of laymen's opinions. I want the scientific facts from professional doctors. Oops, I forgot...now you're saying the doctors are wrong. The following site was updated Jan. 2009, another I visited was updated April 2009. Back up what you're saying. There are news articles on your forum, but none relating specifically with the pros and cons of the sleeve.

Gastric Sleeve Surgery Risks and Complications
Risks and complications include:
Leaking of the sleeve. The operation requires staples to be inserted into the stomach, and there is always a chance that the staples will tear apart, resulting in a leak. The leaking stomach acids frequently become infected and can cause serious problems that may require another operation or a drainage tube.
Blood clots
Weight may be regained over time, because the stomach can stretch.
Unlike gastric banding surgeries, no foreign objects are left in the body during the procedure. With gastric banding, the band may slip, erode or become infected.
Unlike gastric bypass or duodenal switch, there is no bypass of the small intestines with the gastric sleeve, so all nutrients are absorbed and very little chance exists of absorption issues.
Wound infection
Since this procedure is relatively new, long-term risk and benefits are not known.
