Abstract
We experienced a case of heterotopic gastric mucosa of the ileum without Meckel's diverticulm. The patient suffered from abdominal pain and vomiting at 11 year-old. Under the diagnosis of intestinal obstruction, laparotomy was performed. Subserosal hematoma of the ileum was noticed, suggesting the diagnosis of Schoenlein-Henoch's purpura. Histopathological study of resected appendix revealed angitis, which was compatible with Schoenlein-Henoch's purpura. After the operation, she had severe abdominal pain twice for two years. Each time, steroid therapy was effective. At 13 year old, she visited our clinic with severe abdominal pain for the forth episode. Ultrasonographic examination showed intussusception. Hydrostatic reduction was not successful and laparotomy was done. At operation, a mucosal tumor on the antimesenteric side of the ileum, 80cm from the ileocecal valve, was resected. Microscopic examination revealed gastric mucosa. To our knowledge, this is the seventh reported case of heterotopic gastric mucosa in the ileum without Meckel's diverticulum in Japan.
