Perforation of Meckel's diverticulum by roundworm.

An 11-month-old girl child presented with distension of abdomen, constipation, vomiting and fever. X-ray of the abdomen suggested intestinal obstruction. Exploration revealed the distal ileum to be kinked around a band running from the tip of a congested Meckel's diverticulum to the lateral pelvic wall. A small perforation was noticed at the tip of the diverticulum and a live roundworm was found lying free in the peritoneal cavity. The diverticulum along with a segment of adjoining bowel was resected and end-to-end anastomosis done. The diverticulum had a wide lumen and showed no heterotopic tissue on subsequent examination.
