Professor Oh Chang-kyo of Hallim University Gangnam Sacred Heart Hospital, Academic Award of the Korean Intestinal Research Society
Jun 04, 2025
Professor Oh Chang-kyo of the Department of Gastroenterology at Hallym University Gangnam Sacred Heart Hospital (Hospital Director Lee Dong-jin) recently won the Korean Gastroenterology Association Academic Award at the 2025 International Conference of the Korean Gastroenterology Association (IMKASID 2025).
Professor Oh Chang-kyo presented the research results in the American Journal of Gastrointestinal Endoscopic Submucosal Dissection and Conventional Endoscopic Submucosal Dissection for Large Lateral Development Tumors in December last year. The paper was published along with a video of the procedure and received great attention in the clinical field.
This study was a randomized controlled trial (RCT) conducted on patients with lateral developmental tumors larger than 2 cm in the large intestine and rectum, and it was found that underwater ESD performed in the underwater environment improved both the safety and effectiveness of treatment compared to conventional endoscopic submucosal dissection (Conventional ESD).
As a result of the study, submucosal dissection of submucosa showed significant improvements in securing visibility, shortening procedure time, and reducing the risk of bleeding. These results were evaluated as an important basis for showing that submucosal dissection could be an effective and safe new treatment option for the treatment of large-sized colon polyps and early colon cancer in the future.
Lateral spreading tumor (LST) refers to adenoma (polyp) or early colorectal cancer that grows mainly horizontally in the colon or rectal mucosa. It is not in a form that protrudes like a general polyp, but has the characteristic of spreading widely sideways along the mucosal surface, and even if the size increases, it does not infiltrate below the submucosal layer in many cases.
Professor Oh Chang-kyo said, "I am pleased that this study will broaden international consensus on the safety and efficacy of submucosal dissection underwater endoscopic submucosal dissection. We will continue our research to standardize related procedures and expand the evidence base in the future."."
