Intussusception in an adult secondary to an inverted Meckel's diverticulum.

Intussusception secondary to an inverted Meckel's diverticulum is considered to be a rare occurrence. The pathophysiology of the disease process results in a complicated clinical picture of chronic abdominal pain, lower gastrointestinal bleeding, and recurrent obstructive symptoms that may lead to an unnecessary delay in diagnosis. A case of an inverted Meckel's diverticulum as a lead point for an ileocolic intussusception in an adult is presented. The methods of diagnosis and the salient concepts in the surgical management of intussusception are discussed. Special features regarding the pathophysiology and treatment of an inverted Meckel's diverticulum acting as an intussusception are also reviewed.
