Segmental dilatation of the ileum as an unusual cause of gastrointestinal bleeding: report of one case.
We report a case of segmental dilatation of the ileum in a 10-month-old male infant. Intermittent loose black-colored stool passage and normocytic anemia were noted at the initial visits to our hospital. There was no symptom or sign of intestinal obstruction such as abdominal distention or vomiting. On physical examination, he was found to be pale but his abdomen was soft and flat. Digital examination revealed brownish stool tinged with black-colored oil-like stool but no polyp. Laboratory studies excluded coagulopathy, hemolytic anemia and lead poisoning. During hospitalization, he was treated with nothing per mouth, intravascular fluids, ranitidine, and transfusion of packed red blood cells. All examinations including panendoscopy, Technetium-99m (99mTc)-pertechnetate Meckel's diverticulum scan, and double contrast colon series revealed no organic lesion except that 99mTc-red blood cell bleeding scans showed abnormal bleeding in the small intestine. Because of his persistent gastrointestinal bleeding with unknown cause, we did an exploratory laparotomy when the patient was 13 months old and idiopathic segmental dilatation of the ileum was confirmed. The dilated segment is supposed to be idiopathic because of histologically proven normal muscle layers without ectopic tissue. This case suggests that segmental dilatation of the ileum can only present as gastrointestinal bleeding without intestinal obstruction.
