Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
The tubular adenoma group
The anatomical site was determined, and the size and morphology of the polyps were observed. The classification of the microvascular ECV of the polyps and its adjacent normal mucosal microvascular ECV (white light+NBI) was observed, and methylene blue staining was used to approach and magnify the glandular duct opening to observe the IIIL type (pit pattern). Magnified to the maximum magnification of EC endoscopy to the clearest cell level (approximately 520 times), and observed the morphology of the opening of the IIIL type glandular duct and the opening of the colonic innominate groove, including the morphology of cell cytoplasm and nucleus, proportion of opening length to field of view (more than 1 field of view is calculated as 1.0), and ratio of maximum to minimum opening diameter; Distribution characteristics of glandular duct openings.
The tubular adenoma group
Biopsy or removal of polyps for pathological examination. Collect baseline data such as gender, age, BMI, etc. If the pathology confirms a pure tubular adenoma, the observed object will be included in the group for final comparative analysis.
the colonic innominate groove group
The methylene blue staining area of the normal mucosa adjacent to the polyp was observed to identify the colonic innominate groove.Magnified to the maximum magnification of EC endoscopy to the clearest cell level (approximately 520 times), and observed the morphology of the opening of the IIIL type glandular duct and the opening of the colonic innominate groove, including the morphology of cell cytoplasm and nucleus, proportion of opening length to field of view (more than 1 field of view is calculated as 1.0), and ratio of maximum to minimum opening diameter; Distribution characteristics of glandular duct openings.
