Patent vitello-intestinal duct with a rare presentation of reverse intussusception with appendicular agenesis: A case report

Background: Vitello-intestinal duct (VID) is found in approximately 2% of newborns, with patency in about 6%. Failure of obliteration leads to some anomalies, most commonly Meckel’s diverticulum. Protrusion of the small bowel is one of the rare presentations. Case Presentation: A 10-month-old male infant presented with a prolapsed, irreducible polypoid-shaped loop of intestine protruding from the anterior abdomen. On exploratory laparotomy, patent VID was confirmed with appendicular agenesis and reverse intussusception. Gangrenous bowel was resected, followed by end-to-end ileo-ileal anastomosis, with a favorable outcome. Conclusion: Patent VID with ileal intussusception and prolapse is a rare entity, which can be easily diagnosed clinically. A high index of suspicion is needed for any associated gut anomaly in these cases, like appendicular agenesis.
