The SADI-S is a single anastomosis bariatric surgery. It is different from the classic duodenal switch, the gastric bypass (RNY) or sleeve gastrectomy.It is a type of bariatric surgery carried out to lose weight and to mitigate various metabolic issues including type 2 diabetes, dislipidemia, metabolic syndrome, and polycystic ovary syndrome.
This procedure is similar to the sleeve gastrectomy surgery, but a sleeve is created by suturing, rather than physically removing stomach tissue. [73] This allows for the natural ability of the stomach to absorb nutrients to remain intact. [73] This procedure is reversible, is a less invasive procedure, and does not use hardware or staples. [74]
Sleeve gastrectomy was originally performed as a modification to another bariatric procedure, the duodenal switch, and then later as the first part of a two-stage gastric bypass operation on extremely obese patients for whom the risk of performing gastric bypass surgery was deemed too large. The initial weight loss in these patients was so ...
The duodenal switch (DS) procedure, also known as a gastric reduction duodenal switch (GRDS), is a weight loss surgery procedure that is composed of a restrictive and a malabsorptive aspect. The restrictive portion of the surgery involves removing approximately 70% of the stomach (along the greater curvature) and most of the duodenum .
Gastric bypass is indicated for the surgical treatment of severe obesity, a diagnosis which is made when the patient is seriously obese, has been unable to achieve satisfactory and sustained weight loss by dietary efforts and has comorbid conditions that are either life-threatening or serious impairment to the quality of life.
This device fits over a therapeutic double-channel endoscope to create a sutured row of stomach tissue. The tissue helix is advanced from the endoscope, put up against stomach tissue, and turned 2-4 rotations to access the gastric muscle layer. The helix is then retracted towards the scope, bringing the full-thickness acquired stomach tissue ...
Billroth II, more formally Billroth's operation II, is an operation in which a partial gastrectomy (removal of the stomach) is performed and the cut end of the stomach is closed. The greater curvature of the stomach (not involved with the previous closure of the stomach) is then connected to the first part of the jejunum in end-to-side anastomosis.
The first attempt at gastric resection was by German professor and surgeon Christian Michaelis, whose experiment on removing pylorus in animals to resolve gastric obstruction failed. [12] In 1810, his student Daniel Merrem successfully performed the resection of the distal stomach and reconnected the duodenum to the stomach in animal ...
