What is afferent loop obstruction?
Afferent Loop Obstruction. Afferent loop obstruction, also called afferent loop syndrome, is a mechanical complication that infrequently occurs following construction of a GJ. The creation of a GJ leaves a segment of proximal small bowel (duodenum and proximal jejunum) upstream from the anastomosis.
Why is Gastrojejunostomy done?
Gastrojejunostomy is a surgical procedure in which an anastomosis is created between the stomach and the proximal loop of the jejunum. This is usually done either for the purpose of draining the contents of the stomach or to provide a bypass for the gastric contents.
What is a Roux-en-Y Gastrojejunostomy?
Roux-en-Y. 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.
Why is gastrojejunostomy done?
What is a Roux-en-Y gastrojejunostomy?
Is gastrojejunostomy major surgery?
Endoscopic gastrojejunostomy is a minimally invasive procedure. A light sedation may be used along with painkillers. A flexible viewing tube (endoscope) is advanced through the nose, esophagus, stomach, and duodenum into the jejunum. The procedure will be guided by images on the monitor.
How is a gastrojejunostomy performed?
Gastrojejunostomy can be done via either an open or a laparoscopic approach. Percutaneous gastrojejunostomy may be performed, in which a tube is placed through the abdominal wall into the stomach and then through the duodenum into the jejunum.
What is a gastrojejunostomy procedure?
Is gastrojejunostomy a bariatric surgery?
Background: The laparoscopic Roux-en-Y gastric bypass (LRYGB) has been considered a reference procedure in the bariatric surgery. The linear-stapled gastrojejunostomy (GJ) has proved to be safe and effective, but its optimal size referred to postoperative weight loss remains poorly understood.
Can affafferent loop syndrome occur after gastrojejunostomy?
Afferent loop syndrome can occur after some types of gastrojejunostomy. One type is the Billroth II gastrectomy. During the procedure, a surgeon will remove or bypass the lower part of the stomach and attach the remaining upper part of the stomach to a loop of small intestine.
What procedures are associated with afferent loop syndrome?
Classically described with Billroth II gastrojejunostomy, other common procedures such as Roux-en-Y gastrojejunostomy, Roux-en-Y esophagojejunostomy, and the Whipple procedure are also associated with afferent loop syndrome.
What is the afferent loop of the stomach?
The loop going to the upper stomach is the afferent loop. The loop carrying food away from the stomach is called the efferent loop. Afferent loop syndrome can occur after some types of gastrojejunostomy.
What is the function of the efferent loop?
The efferent loop receives and transfers the ingested food and liquids. Afferent loop syndrome is defined by a distal obstruction causing distension of the afferent limb secondary to the accumulation of bile, pancreatic fluid, and proximal small bowel secretions.
