Endoscopic submucosal dissection of a large colonic lipoma: Report of two cases

Jae Min Lee et al. World J Gastroenterol. .

Abstract

A colonic lipoma is a very rare benign tumor that is usually asymptomatic and is found incidentally by colonoscopy. Patients with a large colonic lipoma may present with symptoms such as abdominal pain, bleeding, and colonic obstruction or intussusceptions. We report two patients with large colonic lipomas and symptoms. Standard endoscopic submucosal dissection (ESD) was performed to remove the lipomas instead of conventional surgical bowel resection. No complications were observed during or after the procedure. The tumors were resected en bloc, and the patients were discharged 2 d after ESD with a regular diet. The results indicate that ESD can be applied as safe and effective treatment for a large colonic lipoma.

Figure 1
A colonoscopy revealed a soft and yellowish submucosal tumor. A: Colonoscopic view revealed an approximate 5 cm, yellowish, smooth submucosal tumor on the distal descending colon. B: Markings were made around the tumor on the distal side (anal side) with a dual knife and a lifting solution was injected to make a sufficient submucosal cushion from the muscle layer. C: A precut incision was made on the distal side of the tumor. D: Submucosal dissection was performed with a dual knife, and dissection was done from the distal side (anal side) while visualizing the yellowish tumor surface. E: The tumor was completely dissected from the submucosal layer with the proximal side (oral side) of the mucosal layer remaining. F: The tumor was resected completely without complications.

Figure 2
A colonoscopy revealed a yellowish submucosal mass approximately. A: Colonoscopic view showed an approximate 7 cm, yellowish, smooth submucosal tumor on the proximal ascending colon. B: Markings were made around the tumor on the distal side (anal side) with a dual knife; C: A lifting solution was injected to form a sufficient submucosal cushion. D: Precut incision on the distal side and submucosal dissection were performed with the dual knife. E: Dissection was done with dual and hook knives from the distal side (anal side). F: The tumor was resected as en bloc without complications.
