Gastroschisis: a radiological and clinical review

A retrospective clinico-radiological review was undertaken of 66 consecutive cases of gastroschisis managed at our institution between August 1982 and February 1993. The condition's morbidity and mortality were reviewed, as were its radiological features and their impact upon management. All patients underwent surgery in the first 24 h of life, and the overall survival rate was 92 %. The finding of bowel atresia at operation was associated with a particularly poor outcome, with only two out of five infants surviving. A minority of infants developed serious complications including necrotizing enterocolitis, short-bowel syndrome, persistent small-bowel dysfunction and cholestatic jaundice. Investigation by plain films, contrast studies and ultrasound examinations was necessary and helpful in these patients. Plain film radiography commonly revealed bowel-wall thickening and luminal dilatation, frequently accompanied by generalised abdominal distension. Small-bowel enema was considered to be superior to the conventional follow-through in distinguishing mechanical from functional obstruction in infants with persistent bowel dilatation.
