Endoscopic treatment is an initial possibility, where cautery or argon plasma coagulation (APC) treatment is applied through the endoscope. Failing this, angiography and embolization with particles is another microinvasive treatment option, which avoids the need for surgery and bowel resection.

What is Angiodysplasia of stomach?
Angiodysplasia is an abnormal, tortuous, dilated small blood vessel in the mucosal and submucosal layers of the GI tract. It is the most common vascular abnormality in the GI tract. Although usually readily seen by colonoscopy and angiography, they are often difficult to diagnose in pathologic specimens.
How does a doctor treat a bleeding vein?
In this procedure, your doctor uses a thin plastic tube to deliver medicine to a bleeding blood vessel. This medication closes up the blood vessel and stops bleeding. Cauterizing. Once your doctor identifies the site of the bleeding, they can use cauterization to close off a part of the vein and stop the bleeding.
What causes angiodysplasia in the GI tract?
The cause of angiodysplasia is unknown. But normal spasms occurring in the GI tract may be responsible for the enlargement of blood vessels. This enlargement leads to the development of small pathways between a vein and an artery, which can leak with blood. In addition, age-related weakening of blood vessels may also cause angiodysplasia.
What is the term for enlargement of blood vessels in the stomach?
Your doctor may classify your case as either colon angiodysplasia (enlargement of blood vessels in the colon), or stomach angiodysplasia (enlargement of blood vessels in the stomach).
