2. Sleeve gastrectomy - Wikipedia

   en.wikipedia.org/wiki/Sleeve_gastrectomy

   Sleeve gastrectomy or vertical sleeve gastrectomy, is a surgical weight-loss procedure, typically performed laparoscopically, in which approximately 75 - 85% of the stomach is removed, [1] [2] along the greater curvature, [3] which leaves a cylindrical, or "sleeve"-shaped stomach the size of a banana.

3. Bariatric surgery - Wikipedia

   en.wikipedia.org/wiki/Bariatric_surgery

   Sleeve gastrectomy, also known as a gastric sleeve, is a surgical weight-loss procedure where the stomach size is reduced by the surgical removal of a large portion of the stomach, following along the major curve of the stomach. [2]

4. Endoscopic sleeve gastroplasty - Wikipedia

   en.wikipedia.org/wiki/Endoscopic_sleeve_gastroplasty

   There are at least two mechanisms of peripheral appetite signaling thought to be mediated by ESG: first, increased sense of fullness during a meal leading to meal termination, potentially a result of the intact gastric fundus that serves as a food reservoir and the restriction to gastric expansion (accommodation) during a meal; [2] [4] and ...

   Schematic of gastric bypass using a Roux-en-Y anastomosis. The transverse colon is not shown so that the Roux-en-Y can be clearly seen. The variant seen in this image is retrocolic, retrogastric, because the distal small bowel that joins the proximal segment of stomach is behind the transverse colon and stomach.

6. Gastric bypass surgery - Wikipedia

   en.wikipedia.org/wiki/Gastric_bypass_surgery

   Normally, the pyloric valve at the lower end of the stomach regulates the release of food into the bowel. When the gastric bypass patient eats a sugary food, the sugar passes rapidly into the intestine, where it gives rise to a physiological reaction called dumping syndrome. The body will flood the intestines with gastric content in an attempt ...

7. Gastrectomy - Wikipedia

   en.wikipedia.org/wiki/Gastrectomy

   The alkaline environment causes the retained gastric tissue to produce acid, which may result in ulcers in a rare complication known as retained antrum syndrome. All patients lose weight after gastrectomy, although the extent of weight loss is dependent on the extent of surgery (total gastrectomy vs partial gastrectomy) and the pre-operative BMI.
