Angiodysplasia of the GI tract

About Angiodysplasia of the GI tract

Angiodysplasia is the most common abnormality of blood vessels in the GI tract. It occurs when previously healthy blood vessels degenerate and weaken. The normal smooth muscle in the blood vessels weaken and the thin blood vessel walls are then at risk of bleeding. Angiodysplasia is the second most common cause of gastrointestinal bleeding in people over the age of 60.

Symptoms

Many patients do not have any symptoms. Symptoms may include dark stools, blood in stools, low red blood cells (anemia) and fatigue.

Tests & Diagnostics

A history and physical will be performed. Lab tests will be performed to evaluate blood counts and blood clotting capability. A colonoscopy will often be performed to confirm the diagnosis. Occassionally a special imaging test called a radionucleotide scan will be done to identify the area of bleeding.

Common tests: Complete blood count (CBC), Comprehensive metabolic panel (CMP), Colonoscopy, Iron.

Conventional treatment summary

Treatment is directed at stabilizing any continued bleeding with IV fluid and blood products. Initial treatment is usually achieved by inserting a small tube attached to a camera (endoscope) into the intestine to stop the weakened blood vessels from bleeding. Occasionally, surgical removal of the affected intestine is required to stop the bleeding
