What is an afferent limb?

What is an afferent 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.

How do you fix afferent loop syndrome?

Treatment is almost always surgery. For acute afferent loop syndrome, emergency surgery may be needed. This is to prevent a tear of the loop. The type of surgery will depend on what’s causing the blockage.

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.

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 a Braun Enteroenterostomy?

Braun enterostomy is a type of anastomosis done following a major surgery like pancreaticoduodenectomy (removal of pancreas and a part of the intestine). Enteroenterostomy is an anastomosis (connection) between one part of the small bowel to another (jejunum or ileum).

What is a blind loop?

Blind loop syndrome occurs when digested food slows or stops moving through part of the intestines. This causes an overgrowth of bacteria in the intestines. It also leads to problems absorbing nutrients. The stomach connects the esophagus to the small intestines and is where the majority of food digestion takes place.

What afferent means?

What is the function of efferent neurons?

Efferent, or motor, nerve fibres carry impulses away from the central nervous system; afferent, or sensory, fibres carry impulses toward the central nervous system.
