A Prospective Study to Evaluate the Performance of a Real-time System in the Estimation of Colorectal Polyp Size
Chinese University of Hong Kong
278 participants
May 13, 2025
INTERVENTIONAL
Conditions
Summary
Colorectal polyp size is related to the risk of exhibiting advanced histological features. Moreover, polyps larger than 10 mm are associated with an elevated risk of metachronous advanced neoplasia and colorectal cancer (CRC). Consequently, accurate measurement of polyp size, especially at the 10 mm threshold is critical for risk stratification and surveillance intervals. Furthermore, polyp size is also important for the choice of the appropriate resection procedures. Underestimation may lead to delayed diagnosis, thereby increasing the risk of colorectal cancer, while overestimation may result in unnecessary surveillance endoscopies.
Eligibility
