Mesenteric Meckel’s Diverticulum Presenting with Rectal Bleeding and Intestinal Obstruction in a Child—A Case Report

Abstract

Meckel’s diverticulum (MD) is the most common congenital anomaly of the gastrointestinal tract, resulting from incomplete obliteration or involution of the vitellointestinal duct. MD, also called an ileal diverticulum or stalk of the yolk sac, connects the developing midgut to the yolk sac; it detaches from the midgut by the fifth to seventh week of fetal life and involutes. However, it sometimes persists as MD in 1%–4% of the population. Mesenteric Meckel’s diverticulum (MMD) is an unusual congenital anomaly, located in the mesentery of the ileum and is rarely reported in the literature. Here is a report of a rare case of MMD in a four-year-old child presenting with rectal bleeding and intestinal obstruction. MMD is a rare variant that may mimic other ileal pathologies. Awareness of this entity is required for accurate diagnosis and appropriate surgical management.
