title: [Gastrointestinal bleeding in children--etiology and diagnosis. Survey of patients in a Tel Aviv medical center, in the years 1990 to 1997].
abstract: During 1990-1997 we investigated 201 children with gastrointestinal bleeding. Average age was 3.9 +/- 6 years; 57.2% were males. There were 129 (64.2%) cases of lower and 72 (35.8%) of upper GI bleeding. Complications of upper GI bleeding were more severe than those of the lower: 6 of 8 (75%) patients who deteriorated into hypovolemic shock had upper GI bleeding; 40 of 50 (80%) who required i.v. fluids (crystaloids and/or blood) had also bled from the upper GI tract; but anemia was more frequent (27.7% vs 17%) in lower GI bleeding. The main etiology for upper GI bleeding was peptic ulcer, and for lower GI bleeding anal fissure. Mean hospital stay for upper GI bleeding was 3.87 +/- 2.61 days vs 3.40 +/- 3.51 for lower (not significant). In 34% the etiology of bleeding was undetermined. Although current literature refers to intussusception as a common cause of GI bleeding in infancy, we had no such cases. This difference might have resulted from our diagnoses being made earlier, before mucosal damage could have caused bleeding. We found polyps the second most frequent cause for lower GI bleeding in children. Endoscopy was of more benefit than any other diagnostic method, while barium enema and ultrasound had no diagnostic value. Stool culture did not contribute to diagnosis: only 3 of 36 were positive, so it is only necessary when there is bloody diarrhea.
