INTRODUCTION: Lipomas are the most common benign neoplasms of the colon after adenomatous polyps. Most colonic lipomas are asymptomatic and incidentally discovered. Intussusception is the most frequent complication of submucosal lipoma and its occurrence is directly related to the size of lipoma, usually larger than 2 cm in diameter.
EVIDENCE ACQUISITION: A literature search was performed in Central PubMed up to the end of February 2020, using the following search terms: “colonic lipoma,” “colon lipoma” and “intussusceptions.” Articles were included if they had enough information regarding patient’s symptoms, lipoma characteristics (size, location), preoperative imaging assessment and type of procedure performed.
EVIDENCE SYNTHESIS: In adults, 60-65% of cases of intussusceptions involving the large bowel have a malignant etiology. The preoperative diagnosis may be difficult and abdominal CT is considered the study of choice for diagnosing intussusceptions from colonic lipomas.
CONCLUSIONS: Symptomatic colonic lipomas are a challenging issue related to the miming cancer clinical presentation and should be included in the differential diagnosis of intussusception in adults.
