Gastroschisis update.

Sixty-four infants with gastroschisis have been managed in the 9-yr period, 1970-1979, with four postoperative deaths. The silo technique has been the standard method of management in this series, permitting initial expansion of the abdominal cavity without increased abdominal pressure and respiratory embarassment. Removal of the silo and complete closure of the abdominal wall deficit were possible 5-12 days later. A high proportion of the infants were below 2500 g in weight at birth (61%); and although 3 of the 4 postoperative deaths occurred in the low birth weight group, this did not appear to be a factor in mortality. Associated anomalies occurred in 25 of the 64, but only the coincident intestinal atresias (6) were of major significance. These additional anomalies were not responsible for deaths. Two deaths occurred from problems dating from birth, one from aspiration and the second from sepsis. The other two resulted from postoperative complications resulting in infarction of the midgut. Both were caused in part by failure to adequately enlarge the abdominal wall defect at the time of the initial procedure. Other postoperative complications were relatively few. Although all required intravenous nutritional support, the long term results in terms of growth and development and of intestinal function were quite satisfactory.
