In general surgery, a Roux-en-Y anastomosis, or Roux-en-Y, is an end-to-side surgical anastomosis of bowel used to reconstruct the gastrointestinal tract. Typically, it is between stomach and small bowel that is distal (or further down the gastrointestinal tract) from the cut end. [1]
The Roux-en-Y laparoscopic gastric bypass, first performed and reported on in case studies between 1993 and 1994, [3] is regarded as one of the most difficult procedures to perform by limited access techniques.
Over a 10-year study while using a common data model to allow for comparisons, 9% of patients who received a sleeve gastrectomy required some form of reoperation within 5 years compared to 12% of patients who received a Roux-en-Y gastric bypass. Both of the effects were fewer than those reported with adjustable gastric banding. [43]
This prevents the partially digested food from entering the first and initial part of the secondary stage of the small intestine, mimicking the effects of the biliopancreatic portion of Roux en-Y gastric bypass (RYGB) surgery. This reduces the amount of calories absorbed and causes bile and pancreatic fluids to be redistributed later in the mid ...
Combined restrictive and malabsorptive techniques are called gastric bypass techniques, of which Roux-en-Y gastric bypass surgery (RGB) is the most common. In this technique, staples are used to form a pouch that is connected to the small intestine , bypassing the lower stomach, the duodenum , and the first portion of the jejunum .
Afferent loop syndrome is an uncommon side effect of gastric surgery. [1] The afferent loop is made up of a segment of duodenum and/or proximal jejunum located upstream of a double-barrel gastrojejunostomy anastomosis.
No Roux limb side effects. [citation needed] Similar nutritional problems to RYGB and less than DS. [citation needed] Low risk of intestinal obstruction compared to RYGB and DS. [citation needed] No Dumping syndrome, unlike RYGB. [citation needed] No marginal ulcers, unlike RYGB. [citation needed]
Side-to-side anastomosis and end-to-side anastomosis are two procedures that can be done. Side-to-side anastomosis is preferred as the distal CBD blood supply is poor and more suitable to the laparoscopic approach, which requires limited anterior CBD dissection. Performing an end-to-side anastomosis risks ischemia and recurrent stenosis. [8]
