One hundred and sixty two patients with upper and intermediate gastrointestinal hemorrhage studied under a prospective protocol are reported. Upper endoscopy revealed lesions of the upper gastrointestinal tract in 137 patients (89%); a barium swallow performed to 92 of them failed to confirm the endoscopic diagnosis in 66 (71.7%). In 99m Tc scan suggested ectopic gastric mucosa in 9 cases; Meckel's diverticulum was confirmed by laparotomy in 7 and gastrointestinal duplication in two of them. Selective mesenteric arteriography demonstrated bleeding ileo-cecal varices in one patient. The main causes of gastrointestinal hemorrhage in the current series were duodenal ulcer (22.8%), esophageal varices (14.8%), stress ulcers (14.2%), reflux esophagitis (7.4%), aspirin-induced gastritis (6.8%), gastric ulcer (5.6%) and ectopic gastric mucosa (5.6%). These diagnosis were characteristically distributed according to pediatric age-groups. The source of bleeding could be detected in 90% of the patients studied. A clinical approach to differential diagnosis of patients with gastrointestinal bleeding is presented.

In the United States, four diseases account for the vast majority of cases of lower intestinal bleeding: arteriovenous malformation, diverticulosis, neoplasms, and internal hemorrhoids. In this article the authors discuss less frequent causes of gastrointestinal bleeding. "Common" less frequent causes of gastrointestinal bleeding include solitary rectal ulcer syndrome, colonic varices, mesenteric vascular insufficiency, small bowel diverticula, Meckel's diverticulum, aortoenteric fistula, vasculitis, small intestinal ulceration, endometriosis, radiation-induced injury, and intussusception. Less frequent causes of gastrointestinal bleeding that have been recently described include portal colopathy, diversion colitis, and gastrointestinal bleeding in runners.

The epidemiology of gastrointestinal bleedings is poorly known in France. The principal source of bleeding comes from upper gastrointestinal tract. The most common etiology of upper gastrointestinal bleeding is peptic ulcer. Non steroidal anti-inflammatory drugs absorption is frequently associated with ulcer bleeding. The second most frequent etiology is variceal hemorrhage, complicating mostly alcoholic cirrhosis. The causes of lower gastrointestinal tract bleeding are more difficult to detect. The major causes are: colonic diverticula, angiodysplasias, traumatic ulcers of the rectum, colorectal carcinomas and colitis. In children, peptic ulcers and varices are the two main causes of upper gastrointestinal bleeding. Etiologies of lower gastrointestinal bleeding are varying according to the age: juvenile polyposis in children less than 6 years and Meckel's diverticulum after 6 years.
