What is an afferent limb in gastric bypass?

What is an afferent limb in gastric bypass?

Afferent loop syndrome is a problem that can occur after some kinds of stomach surgery. It’s also known as afferent limb syndrome. The small intestine loop has 2 loops. The loop going to the upper stomach is the afferent loop. The loop carrying food away from the stomach is called the efferent loop.

What is 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.

What is a Roux-en-Y technique?

Gastric bypass, also called Roux-en-Y (roo-en-wy) gastric bypass, is a type of weight-loss surgery that involves creating a small pouch from the stomach and connecting the newly created pouch directly to the small intestine.

Where is the afferent limb?

The afferent loop consists of the duodenal stump, the remainder of the duodenum, and the segment of jejunum proximal to the gastrojejunostomy. The clinically relevant portion of the loop pertaining to ALS is the jejunal portion of the afferent limb.

What is Billroth II gastrojejunostomy?

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.

What is the Roux limb made of?

This limb contains digestive juices from the stomach, bile and pancreas. The Roux limb, the middle portion of the small intestine also known as the jejunum, is connected to the pouch. Food flows directly from the pouch into the Roux limb, bypassing most of the stomach.

What is partial gastrectomy with Gastrojejunostomy?

The Billroth II always follows resection of the lower part of the stomach (antrum). The surgical procedure is called a partial gastrectomy and gastrojejunostomy. The Billroth II is often indicated in refractory peptic ulcer disease and gastric adenocarcinoma.

Is Roux-en-Y restrictive or malabsorptive?

Roux-en-Y is the most common type of gastric bypass surgery. The procedure involves stapling the stomach to create a small pouch that holds less food. We shape a portion of the small intestine into a “Y.” Roux-en-Y is: Malabsorptive (limits food absorption)

How does Roux-en-Y alter macromolecule and nutrient digestion and absorption?

Bypassing part of the intestine reduces how much food and nutrients are absorbed. This leads to weight loss. One type of gastric bypass surgery is a Roux-en-Y gastric bypass. In normal digestion, food passes through the stomach and enters the small intestine, where most of the nutrients and calories are absorbed.
