Abstract
The first case is a newborn girl who was identified as having a cystic lesion in abdominal cavity at fetus, and developed the intestinal obstruction three times in newborn period. The second case gave rise to anemia and melena due to intestinal ulceration. According to review of 86 cases, our two cases and 84 cases from the literature, we made a detailed analysis of clinical and pathological picture about segmental dilatation of the intestine (SD). SD is recognized at all parts of intestine. From the difference of originated part, associated anomalies, and existence of ectopic tissue, we speculate that SD is caused by different pathology. Because the prognosis is most satisfactory by means of resection of the dilated segment, it is important that the existence of SD is widely known and diagnosed exactly before operation.
