Incarcerated Hernia with Ileal Perforation in an Extreme Preterm Infant.

We describe a case of a premature 24 weeks gestation infant who presented with clinical lability and abdominal distention with initial concerns of necrotising enterocolitis. On further examination, a right inguinal hernia was noted and serial abdominal X-rays showed bowel loop dilatation with intramural air and no perforation. However, the hernia was recurrent and later found to be not reducible. He underwent right groin exploration. Intraoperatively, distal ileal perforation was noted and he was found to have an additional five sites of perforation. He had a stoma sited at the left iliac fossa as well as primary anastomosis at the site of the second to fifth perforations. He had a stormy postoperative period but is currently doing well. Although obstructed hernias are rare in the initial course of an extreme preterm infant, it should not be missed as a cause of intestinal obstruction and early surgical opinion should be sought.
