CHICAGO—Underwater endoscopic mucosal resection has numerous advantages over the conventional approach for the resection of colorectal polyps, according to a meta-analysis presented at Digestive Disease Week 2023.
“We found that for all lesions, irrespective of their size, underwater endoscopic mucosal resection [U-EMR] outperforms conventional EMR [C-EMR] in terms of en bloc resection, R0 resection and rate of polyp recurrence,” said Saurabh Chandan, MD, an assistant professor of gastroenterology at Creighton University School of Medicine, in Omaha, Neb.
However, the data are less clear for lesions larger than 20 mm, he added. “I would say that U-EMR is comparable to C-EMR, and perhaps somewhat more favorable” in these instances, he said.
