[2] About 2/3 of all GI bleeds are from upper sources and 1/3 from lower sources. [14] Common causes of gastrointestinal bleeding include infections, cancers, vascular disorders, adverse effects of ...
Gastric antral vascular ectasia (GAVE) is an uncommon cause of chronic gastrointestinal bleeding or iron deficiency anemia. [1] [2] The condition is associated with dilated small blood vessels in the gastric antrum, which is a distal part of the stomach. [1] The dilated vessels result in intestinal bleeding. [3]
Recurrent or refractory bleeding may lead to need for surgery, although this has become uncommon as a result of improved endoscopic and medical treatment. Upper gastrointestinal bleeding affects around 50 to 150 people per 100,000 a year. It represents over 50% of cases of gastrointestinal bleeding. [2]
Treatment is indicated if there is active bleeding in the stomach, visible vessels, or an adherent clot. Endoscopy is also helpful in identifying people who are suitable for hospital discharge. Prokinetic agents such as erythromycin and metoclopramide can be given before endoscopy to improve endoscopic view. Either high- or low-dose PPIs are ...
Portal hypertensive gastropathy can also be treated with endoscopic treatment delivered through a fibre-optic camera into the stomach. Argon plasma coagulation and electrocautery have both been used to stop bleeding from ectatic vessels, and to attempt to obliterate the vessels, but have limited utility if the disease is diffuse.

Therapeutic endoscopy is the medical term for an endoscopic procedure during which treatment is carried out via the endoscope. This contrasts with diagnostic endoscopy, where the aim of the procedure is purely to visualize a part of the gastrointestinal, respiratory or urinary tract in order to aid diagnosis.
