Afferent Loop Syndrome - Medtick

Afferent Loop Syndrome

What is it?

It is an uncommon obstruction between stomach and the first part of the small intestine.

  • Fluids from the pancreas and bile duct flow through the first part of the small intestine up to the stomach.
  • If a partial or complete blockage happens in this part of the small intestine (also known as the afferent limb of the small intestine), then problems can occur.
  • This afferent loop syndrome can cause abdominal or back pain, nausea, and vomiting.
  • If the obstruction is severe, this could affect the pancreas, the bile duct and liver, the duodenum, and the afferent limb.

  • Afferent loop syndrome is a problem that can occur after some kinds of stomach surgery.
  • It occurs when something traps the flow of digestive juices in the afferent limb. Fluid pressure builds up in the limb and causes discomfort and nausea.
  • Common symptoms are abdominal pain, nausea, and sudden vomiting of fluid with bile in it.
  • Treatment is almost always surgery. For acute afferent loop syndrome, you may need emergency surgery.
