Abstract
A 12-year-old male boy, whe had been suffered from anemia at the age of 6, was admitted to the hospital because of lower abdominal pain. His blood chemistry showed iron-deficiency anemia. After admission the pain was intensified and peritoneal stimulating sign developed. He was diagnosed as having acute appendicitis and operated on. At the surgery, slight-blood a scites was detected and perforated Meckel's diverticulum 6cm×3cm, in size was revealed at antimesenteric side of the ileum which was 90cm from the ileocecal valve. A wedge resection of the diverticulum was carried out. The appendix was intact. Pathological examination revealed that there we ectopic gastric parietal gland at the apex of the diverticulum. The perforation was in the area of ileal mucosa near the ectopic gastric mucosa. It was active peptic ulcer. Helocobacter pylori was not found in the ectopic mucosa with May-Giemsa staining. In this case, gastric acid and/or pepsin rescreted from the ectopic mucosa should cause peptic ulcer in the ileal mucosa, and then hemorrhage and perforation developed.
