Colonic intussusception caused by colonic lipoma: A case report

Abstract

Intussusception is a pediatric condition that rarely presents in adults. Colonic lipomas 4 cm and more in diameter can cause colonic intussusception leading to emergency operation. Surgical resection of the involved segment must be the procedure of choice. We report a case of colonic intussusception caused by colonic lipoma in an adult. The patient underwent operation, and histopathological examination of the specimen confirmed the diagnosis of colonic submucosal lipoma.

Intestinal Submucosal Lipomas

“…The treatment of lipoma depends on its symptoms. It is considered that the size of lipoma is a predictor of symptomatology and lipomas larger than 4 cm produce symptoms [4]. *Capsule was visible on naked eye and microscopically in 24 cases, in additional 14 cases it was visible only microscopically and in 2 cases it was not visible at all.…”

“…The vast majority is asymptomatic but rarely, they may cause ulceration of mucosa, perforation, intussusceptions, prolapsed, obstruction, and massive hemorrhage and may cause surgical emergencies [2,4,5,10,12].…”

“…Lipomas are the most common benign nonepithelial intestinal tumors and are the second most common type of benign tumor of the colon, after adenomatous polyps [2][3][4].…”

Acute intussusception on a lipoma of the left colon: report of a case

“…[4] They often remain asymptomatic. [5] For that reason, they are, usually, incidentally identified during imaging studies, colonoscopy, surgery or autopsy. [4,6] Though symptoms are rare, they are more frequent with large pedunculated lipomas (larger than 3 cm).…”

“…[1] In addition, over a period of 45 years, only 46 cases of colonic intussusception secondary to colonic lipomas have been reported in the English language literature. [5] Clinically, symptomatic intussusception presents as an acute intestinal obstruction. Recurrent bowel obstruction may occur due to intermittent spontaneous reduction and re-intussusception, as was the case with this patient.…”
