title: Developmental aspects of gastroschisis.
abstract: The development of gastroschisis was studied experimentally as well as clinically, particularly concerning the characteristic fibrous coating of the protruding bowel loops, associated intestinal atresia, and postoperative hypoperistalsis without intestinal obstruction. Experimental investigation was carried out in the chicken embryo. The clinical study was a joint one, involving a total of 50 patients with gastroschisis seen at the Sophia Children's Hospital, Rotterdam, and the Royal Hospital for Sick Children, Glasgow, between 1972 and 1985. Some patients were followed antenatally. The results, correlating with previous experiments, were compared with data from the literature. The fibrous coating of the protruding bowel loops appeared to be a late occurrence and directly related to changes of the amniotic fluid secondary to the onset of renal function. Associated intestinal atresia and postoperative hypoperistalsis in the absence of an obstruction both appeared to be due to another late gestational event, consisting of ischemic changes of the bowel wall secondary to the compression of bowel loops and mesentery in the small abdominal wall defect.
