The radiology of Meconium Ileus Equivalent

DW Pilling and GM Steiner

Meconium Ileus Equivalent is a condition which occurs in patients with cystic fibrosis where the ileum becomes obstructed by bowel content of abnormal consistency. Intercurrent chest infection or absence of pancreatic extract supplements are often the exacerbating cause. Plain films of the abdomen show small bowel obstruction and in some a nodular pattern in the small bowel, the nodules being larger than those seen in quiescent cystic fibrosis. Gastrografin enemas and/or enemas with acetyl cysteine can be used in the treatment of the condition, the Gastrografin having the advantage of confirming the diagnosis radiologically. The condition is important as it can be the presenting feature of cystic fibrosis in childhood and even in early adult life, and the operative mortality and morbidity are high. Conservative treatment should be pursued vigorously and operation only undertaken if unavoidable.
