Management of the fetus with an abdominal wall defect: experience of 31 cases.
The diagnosis of ventral abdominal wall defect can now be made prior to birth. With this diagnosis, the family can make decisions and a planned optimal management can lead to a successful outcome. There were 31 cases of ventral wall defect identified at Chang Gung Memorial Hospital (CGMH) from January 1979 through March 1988. Twenty of them were classified as gastroschisis; among them, 17 (85%) were born in outside clinics and none of them had associated anomalies. In contrast, among 11 cases of omphalocele, there was a lower frequency of transferred cases (27% vs 85%), and 4 cases had additional defects, including two multiple anomalies and two bladder exstrophies. There were no significant differences between gastroschisis and omphalocele in the mortality rate (30% vs 36%), in the incidence of intrauterine growth retardation (IUGR) (30% vs 27%) and in the Cesarean section rate (15% vs 18%). All 4 cases of prematurity (less than 36 weeks of gestational age) expired after delivery and 2 of these had body weights of less than 1500 g. Three out of 5 cases delivered by Cesarean section expired; the mortality (60%) was higher than that of vaginal delivery (28%). All 3 cases were gastroschisis, 2 of them were transferred from outside clinics and all expired due to sepsis. The diagnosis of ventral wall defect should be made prenatally, with obstetric ultrasonography, maternal serum alpha-fetoprotein screening and fetal karyotyping. Therefore, fetal transport in utero to a referral center and optimal perinatal care for those fetuses with potentially correctable lesions can be well planned.
