Is It Safe For Endoscopic Piecemeal Mucosal Resection In Treating Large Sessile Colorectal Polyps?
Endoscopic resection of large sessile colorectal polyps is increasingly used as an alternative to surgery, but remains challenging because of its technical difficulty, the high risk of complications such as bleeding or perforation, and the possibility of coexisting malignancy. This research, lead by Dr. Sohn DK and his colleagues at the National Cancer Center, Korea, demonstrated the safety of endoscopic piecemeal resection (EPMR) for large sessile colorectal polyps and the research has recently been published on June 14, 2010 in the World Journal of Gastroenterology. The authors included a large number of polyps with significant numbers of malignancies and were able to demonstrate that relapse was low in patients with benign polyps after endoscopic resection. The research group enrolled 47 patients with 50 large sessile polyps (2 cm or greater in diameter) who underwent EPMR using a submucosal saline injection technique and observed them during follow-up examinations over a median per
