Abstract

Meckel's diverticulum has an incidence of 2-4% and is the most common congenital defect of the gastrointestinal tract. It is usually asymptomatic, it may become clinically evident in the presence of complications such as haemorrhage, obstruction or diverticulitis. We here report the case of a young patient of 11 years old with intestinal obstruction caused by a volvulus over a loop formed by the adhesion of Meckel's diverticulum to the cecal appendix. In most cases, the formation of volvulus is associated to the persistence of a fibrous band residual from the vitelline arteries attaching the tip of the diverticulum to the abdominal wall providing the momentum which initiates the volvulus. In our case, the volvulus had formed despite the absence of the mesodiverticular band because of the presence of a most uncommon feature: a loop constituted by the Meckel's diverticulum attached to the cecal appendix by an adhesive inflammatory reaction.
