Small bowel malformations

Vascular malformation of the small intestine is one of the important causes of acute and chronic gastrointestinal bleeding. There are often no special clinical symptoms and signs. In the early stage, it is occult bleeding or chronic bleeding. It is often seen for repeated gastrointestinal bleeding or major gastrointestinal bleeding. It is difficult to find the site of the lesion due to routine examination and laparotomy, which leads to no cure or wrong surgical treatment. In 1960, Magulis first reported the use of intraoperative arteriography to confirm vascular malformations in the gastrointestinal tract. In 1965, Baum first applied percutaneous selective mesenteric angiography to diagnose this disease, which gradually increased the rate of detection of this disease. The preferred method for diagnosis of this disease. The etiology of this disease is complex, including congenital and acquired factors. Therefore, the names and classifications have not been unified. The names used in domestic and foreign literature reports are: angiodysplasia of the small intestine, arteriovenous malformation, vascular ectasia of the small intestine, telangiectasia of the small intestine, Small intestine hemangioma (hemangioma), etc., but most scholars believe that the name of vascular malformation can describe a variety of lesions, is more commonly used, and easy to accept.
