What is afferent and efferent limb?

What is afferent and efferent limb?

The afferent limb transfers bile, pancreatic, and proximal intestinal secretions distally towards the anastomosis (gastrojejunostomy in Billroth II/Whipple procedures and jejunojejunostomy in Roux-en-Y). The efferent loop receives and transfers the ingested food and liquids.

What is the afferent limb?

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. Afferent loop syndrome can occur after some types of gastrojejunostomy.

What is Roux syndrome?

The Roux limb syndrome is a symptom complex characterized by chronic postprandial epigastric pain, fullness, and vomiting observed in approximately one third of patients after gastric reconstructive surgery for reflux gastritis and other conditions in which vagotomy and Roux-en-Y gastroenterostomy have been preformed.

Why do they call it a Roux-en-Y?

The name is derived from the surgeon who first described it (César Roux) and the stick-figure representation. Diagrammatically, the Roux-en-Y anastomosis looks a little like the letter Y.

What is the best definition of afferent?

(Entry 1 of 2) : bearing or conducting inward specifically : conveying impulses toward the central nervous system — compare efferent.

Is the afferent limb the same as the Roux limb?

It appears that the afferent limb is the same as the roux limb (= proximal to the gastrojejunal anastomosis) and the efferent limb is distal.

How is the distance of the Roux limb measured?

A distance of 40 cm will be measured distal to the efferent cut end and the afferent limb will be anastomosed at this point. The efferent limb or the roux limb will be brought up in a retrocolic and retrogastric route and anastomosed to the common hepatic duct.

How is a Roux limb formed in a gastrectomy?

A Roux limb may be formed in multiple different gastrointestinal surgeries, including In these procedures, the small bowel is divided at some point. This leaves two components of small bowel: The end of the distal component is dragged up and connected (anastomosed) to the remnant stomach (or esophagus in the case of total gastrectomy).

How is Roux en Y anastomosis used in surgery?

Roux-en-Y anastomosis. Jump to navigation Jump to search. 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.
