Gastroschisis: a 15-year experience

Between January 1, 1971 and December 31, 1985, 59 cases of gastroschisis were treated at Hôpital Sainte-Justine in Montreal. In the period before 1978, 6 of 19 patients (31.6%) were closed primarily at the time of surgery and 13 of 19 patients (68.4%) had silon pouch closure. After 1978, 33 of 40 patients (82.5%) had primary closure and 7 of 40 (17.5%) had a silon pouch. Our overall mortality rate was 13.6%. The complication rate for the primary closure group was 25.6% with a 12.8% (5/39) mortality rate, interestingly, in the higher birth weight group. Those closed with a silon pouch had a 75% complication rate, mostly infectious, with 15% mortality. Neither low birth weight nor gestational age influenced mortality. A significant difference in the length of hospital stay was observed. This was 33.6 days for the primary closures and 56 days for the silon pouch closures. Our series demonstrates a definite favorable trend in the results of treatment of this malformation. The most important factor affecting these results is a change in surgical approach. Primary abdominal wall closure, being usually possible, should always be attempted. We also note an association between high birth weight and death due to bowel dysmotility.
