Abstract

Introduction: Intussusception is a relatively common condition seen in children. In comparison, adult intussusception is rare and is often secondary to inflammatory diseases, benign or malignant tumors and motility disorders. Being a benign cause, lipomas appear as a particularly rare gastrointestinal tumor.

Presentation of case: We present a case of colo-colonic intussusception secondary to a sigmoidal lipoma, in a 40-year-old man. We describe the different aspects of diagnosis and management of this rare complication.

Discussion: Adult intussusception is the cause of symptomatic bowel obstruction in 1% of cases and its colo-colonic occurrence represents 17% of all intestinal intussusceptions. The case that we describe is particularly unique because apart from being an example of intussusception in adults, it occurred in the sigmoid colon and was not associated with a malignant lesion. The treatment of intussusception in adults is surgical resection because of the high incidence of underlying malignancy. Colonoscopy is a modality which allows direct visualization of the lipoma. However, intraluminal reduction via colonoscopy is not recommended.

Conclusion: Colo-colonic intussusception is a very rare complication of lipoma. It is determined that the treatment is surgical due to the risk of malignancy.
