U.S., Jan. 21 -- ClinicalTrials.gov registry received information related to the study (NCT07351890) titled 'Diagnostic Accuracy of EUS for Colorectal Submucosal Masses' on Dec. 31, 2025.
Brief Summary: This study aims to evaluate the diagnostic accuracy of endoscopic ultrasound (EUS) for colorectal submucosal tumors/lesions (SMTs/SELs) and to identify factors associated with correct EUS diagnosis. Using cases with histopathologic confirmation as the reference standard, EUS-based preoperative diagnoses will be compared with final pathology to estimate overall accuracy and accuracy across different lesion types. Potential influencing factors-including lesion location, size, echogenicity, layer of origin, image quality, operator experience a...
