Endoscopic Resection of Giant Colonic Lipoma: Case Series with Partial Resection
A 65-year-old female was referred to our center due to a giant colon lipoma detected on a colonoscopy. The patient had intermittent abdominal discomfort in the right lower quadrant. A wide-based 3×3-cm size yellowish protruding mass without mucosal change was detected at the ileocecal valve during colonoscopy (). We planned to perform an unroofing technique with a snare catheter (ASM-1-S; Wilson-Cook Medical Inc., Winston-Salem, NC, USA) at the center of the lesion so that the remaining lipoma could flow out of the exposed surface. It was deemed as appropriate to remove the roof of the center because the wide base of the lipoma could impede the conduction of electric current. ERBE ICC 200 (Elektromedizin, Tubingen, Germany) was used as the electrosurgical unit; at the Endo-cut mode (120 W, effect 3), partial resection was performed twice, each time lasting for less than 5 seconds, to resect about half of the mass (). Typical yellow tissue indicating lipoma could be seen on the exposed surface (). The patient was relieved of the abdominal discomfort afterwards. At 3-year follow-up colonoscopy, a surgical scar was observed but not any remaining lipoma ().
