The gastric bypass group had an average peak alcohol breath level of 0.08%, whereas the control group had an average peak alcohol breath level of 0.05%. It took an average of 108 minutes for the gastric bypass patients group to return to an alcohol breath of zero, while it took the control group an average of 72 minutes. [journal 15]
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.
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.
Gastroenterostomy, anastomosis of gastric cardia to jejunum. A gastroenterostomy is the surgical creation of a connection between the stomach and the jejunum.The operation can sometimes be performed at the same time as a partial gastrectomy (the removal of part of the stomach).
A single protocol is not superior to the other. In one 2019 systematic review, estimated weight loss (EWL) for each surgical protocol is as follows: 56.7% for gastric bypass, 45.9% for gastric banding, 74.1% for biliopancreatic bypass +/- duodenal switch and 58.3% for sleeve gastrectomy. [28]
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.
The Stamm gastrostomy is an open technique, [4] requiring an upper midline laparotomy and gastrotomy, with the catheter brought out in the left hypochondrium.It was first devised in 1894 by the American Gastric Surgeon, Martin Stamm (1847–1918), who was educated greatly in surgery when he visited Germany.
A jejunostomy may be formed following bowel resection in cases where there is a need to bypass the distal small bowel and/or colon due to a bowel leak or perforation. Depending on the length of jejunum resected or bypassed the patient may have resultant short bowel syndrome and require parenteral nutrition .
