Endoscopic resection of gastrointestinal lipomas: a single-center experience.
Surg Endosc. 2014 Jan; 28(1):185-92.SE

Abstract

BACKGROUND

Gastrointestinal (GI) lipomas are benign, slow-growing subepithelial tumors. Most lipomas are detected incidentally at endoscopy, but they can cause GI bleeding, abdominal pain, intestinal obstruction, and intussusception, particularly if they are larger than 2 cm in diameter. The aim of this study was to investigate the efficacy, safety, and long-term prognosis of endoscopic treatment of GI lipomas.

METHODS

A total of 28 GI lipomas treated endoscopically from January 2005 to June 2012 were retrospectively reviewed. Endoscopic treatment was performed by four methods: the unroofing technique, endoscopic mucosal resection (EMR), EMR after precutting (EMR-P), and endoscopic submucosal dissection (ESD).

RESULTS

Of 28 GI lipomas, 5 were located in the stomach, 2 in the duodenum, and 21 in the colon. Thirteen lipomas were <2 cm in diameter (small lipoma), and the other 15 were ≥2 cm (large lipoma). The unroofing technique was performed in 2 cases, EMR in 17 cases, EMR-P in 4 cases, and ESD in 5 cases. En bloc resection was performed with 21 lesions (75 %), and endoscopic complete resection was achieved with 26 lesions (93 %). Incomplete resection occurred in the 2 cases treated by the unroofing technique. On pathologic examination, complete resection was achieved with 21 lesions (75 %). Delayed bleeding was observed in one patient. There were no serious complications such as perforation or post-procedural stricture. During the mean follow-up period of 19 months (range 2-91 months), no recurrence was observed.

CONCLUSIONS

Endoscopic treatment appears to be a safe and effective treatment for GI lipomas, including large lipomas (≥2 cm in diameter).
