Colonic intussusception from pedunculated colonic lipoma at hepatic flexure: a case report and review of current literature

Colonic lipomas are a benign tumor that can present in multiple ways, including; incidentally, abdominal pain, change in bowel habit, bleeding, intestinal obstruction and intussusception. We present the case of a 48-year-old gentlemen who presented to the emergency department with a 3 day history of abdominal pain and was found to have a 5 cm intramural ischemic pedunculated colonic lipoma causing intussusception and large bowel obstruction. He received initial management with emergency laparoscopic exploration, reduction of intussusception, colotomy and lipoma excision. He made a full recovery. The current approaches to management of colonic lipomas are conservative, endoscopic or surgical. This case highlights the potential consequences of untreated colonic lipomas. In our review of the literature, we highlight that there is a lack of clear consensus on appropriate management of these patients.
