Endoscopic Resection of Giant Colonic Lipoma: Case Series with Partial Resection
A 46-year-old female was referred to the center with a colonoscopic finding of 3×3 cm giant lipoma at the sigmoid colon during a health examination performed 3 years ago. Being asymptomatic, the patient had been followed on an outpatient basis but was referred to our center due to continued abdominal discomfort in the left lower quadrant. A wide-based 3×3-cm yellowish globular mass without mucosal change was detected 30 cm above the anal verge during colonoscopy (). Partial resection technique was performed with a snare catheter at the center of the lesion so that the remaining lipoma could flow out of the exposed surface (). Since the mass was attached in a globular form, snare catheter was placed slightly apart from the base for optimal constriction. At the Endo-cut mode (120 W, effect 3), partial resection was performed for less than 10 seconds to resect most of the mass. Typical yellow tissue indicating lipoma could be observed on the exposed surface (). The colonoscopic finding at the next day confirmed flowing out of the remaining lipoma tissue at the exposed lesion (). The patient was relieved of the abdominal discomfort afterwards. At 1-year follow-up colonoscopy, a surgical scar was observed but not any remaining lipoma ().
