[Two cases of blind pouch syndrome].

Case 1. A 39-yr-old male was presented with anemia. Initial blood examination showed remarkable iron deficiency anemia. Small bowel X-ray and abdominal CT examination revealed a dilated tract at the end of the ileum. Surgical operation was done. The surgical specimen showed side to side anastomosis which was reconstructed at the operation for rt. inguinal herniation 46 days after his birth. The oral side of the tract was remarkably dilated. Case 2. A 50-yr-old male was presented with dizziness. He had anemia and clubbed fingers. A small bowel X-ray examination was done and it showed side to side anastomosis in the middle of the small intestine. Surgical operation was performed. The surgical specimen showed side to side anastomosis about 2 m 20 cm from the Treitz' ligament, which was reconstructed during the operation for ileus when he was 10 years old. The blind portion was remarkably dilated. In both case, the anemia was improved after the operation.
