title: [Usefulness of endoscopy in the differential diagnosis of hemorrhage of the upper digestive tract in children].
abstract: 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.
