EP.FRI.874 Laparoscopic Assisted Submucosal Excision of an Intussuscepted Colonic Lipoma through a Colotomy; A New Technique

Lipomas are the most common non-epithelial tumours of the colon. Nevertheless, symptomatic colonic lipomas are a rare entity in adults. Intussusception is the commonest complication of submucosal lipomas and often presents with absent, non-specific or intermittent symptoms, hence the diagnosis is challenging. In non-emergency situations, most patients undergo computed tomography scan as well as endoscopic evaluation of the colon prior to any surgical intervention. While successful endoscopic excision of lipomas has been reported, segmental resection of the colon is most commonly practiced. To the best of our knowledge, this is the first report of laparoscopic assisted submucosal excision of an intussuscepting colonic lipoma through a colotomy. We present the case of a young female patient with few weeks history of intermittent abdominal pain associated with nausea. She had previously undergone various investigations including colonoscopy and was awaiting an elective left hemicolectomy. She presented to our Emergency department with subacute large bowel obstruction. A CT scan confirmed the diagnosis of colo-colic intussusception due to a large descending colon lipoma. The patient underwent a laparoscopic assisted procedure - following laparoscopic colonic mobilisation, submucosal excision of the large lipoma was performed through a colotomy placed through the taenia on the opposite wall. The mucosal defect and colotomy were closed following the excision. The patient recovery was uneventful and histopathology of the specimen confirmed the diagnosis.
