Double Meckel’s Diverticulum Presenting as Acute Appendicitis: A Case Report and Literature Review

BackgroundMeckel’s diverticulum is the most common developmental anomaly of the gastrointestinal tract, affecting 1–3% of the general population. This anomaly is caused by incomplete obliteration of the omphalomesenteric duct during the 7th week of gestation and is located in the last meter of the ileum in 90% of patients. Meckel’s diverticulum is often an incidental finding during a laparotomy for other causes, such as acute appendicitis, and occasional complications are bleeding, obstruction, diverticulitis, and perforation.ObjectivePrimary aim of this study was to present and share an extremely rare case of double Meckel's diverticulum.MethodsA 20-year-old woman who was admitted due to symptoms of right lower quadrant pain, nausea, and vomiting. A laparotomy with a McBurney’s incision was performed because of a presumed diagnosis of acute appendicitis. The surgical exploration revealed a double Meckel’s diverticulum localized 50 cm proximal to the ileocecal valve, but no acute appendicitis. The operation was finished after a diverticulectomy and appendectomy. No complications occurred during the postoperative follow-up.ConclusionsWe conducted a literature review of studies published in the English language on double Meckel’s diverticulum, accessed via PubMed, Medline, and the Google Scholar databases. We found only five case reports of such a Meckel’s diverticulum variant.
