[Usefulness of small-bowel capsule endoscopy in gastrointestinal bleeding]

In France, upper gastrointestinal haemorrhages have an estimated annual incidence of 143 cases per 100,000 inhabitants. Classically, two types of digestive hemorrhage are described: acute and chronic digestive hemorrhages. Upper endoscopy is carried out in case of hematemesis or melena. It requires that the patient has been fasting for at least 6hours for solids and 3hours for liquids. The main etiologies of hemorrhagic hemorrhage of the origin are the vascular abnormalities, inflammatory or drug-induced ulcerations, intestinal tumors, Meckel's diverticulum, and Dieulafoy ulcer. The modalities of exploration of the small intestine before digestive hemorrhage are the wireless capsule, a reference examination for the exploration of the small intestine, enteroscopy, therapeutic examination, entero-CT or MRI, and 99mTc-labeled red blood cell scintigraphy. In this review, we will discuss the different etiologies of the digestive haemorrhage of intestinal origin and propose a management algorithm.
