Overview
This study is to analyze the characteristics of the IIIL opening of the duct in tubular adenoma and the colonic innominate groove under EC endoscopy, in order to improve the ability to tell lesions and the colonic innominate groove under EC endoscopy (Endocytoscopy).
Description
This is a prospective cohort study. The recruitment time for all participants will be 4 months. The tubular adenoma group and the colonic innominate groove group will be paired in a 1:2 ratio, with 32 lesions of tubular adenoma and 64 adjacent innominate groove. It is expected that there will be 32 cases and a total of 96 observation subjects. Analyze and compare the characteristics of the opening of the IIIL duct in tubular adenomas and the colonic innominate groove under EC endoscopy, in order to summarize and differentiate them.
