Abstract
We've experienced 63 cases with gastric rupture at our hospital from 1966 to 1991. Twin cases were detected in 7 (11%) of the 63 cases. In Japan, the frequency of twin is about 0.6% out of the delivery. In this study, we've evaluated the reason of the high frequency in twin cases. Of the 7 twin cases, 6 were of prematurities (birth weight l,690 ± 690g), 2 were with asphyxias, and 5 had another associated diseases (RDS, volvulus, NEC, hyperviscosity syndrome, sepsis). The site of perforation were detected at lesser curvature in 3, and size was very small in 3 cases. These findings suggest that the reason of the high frequency in twins is due to the disturbance of blood flow and ulcer formation contributing to anoxia in the stomach during perinatal period. We concluded that the frequency of gastric rupture in twins would be reducible by the improvement of perinaal care.
