Can a scope see beneath the surface? study tests ultrasound accuracy for colorectal masses

This study looked at 270 patients to see how accurate endoscopic ultrasound (EUS) is at diagnosing colorectal submucosal masses (growths under the lining of the colon or rectum). Researchers compared the EUS results with the final tissue diagnosis from biopsies or surgery. They also examined factors like the mass's size, location, and the doctor's experience to find what helps make a correct diagnosis. The goal is to improve how doctors use EUS to guide treatment decisions.
