Abstract:
Objective To compare the detection rate of right hemicolonic polyp between indigo carmine staining and white light endoscopy.Methods A total of 1052 patients with colonoscopic examination in Qing-baijiang District People's Hospital of Chengdu City from July 2022 to March 2023 were selected as the study subjects and divided into the indigo carmine staining group and white light endoscopy group,526 cases in each group.The right hemicolon was observed by indigo carmine staining and white light pattern respectively.The difference in the detection rate of right hemicolonic polyp was compared between the two detection methods. Results Compared with the white light endoscopic examination group,the detection rate of the right hemico-lonic polyp (41.6％),detection rate of the right hemicolon adenoma (20.9％),detection rate of wide basal ser-rated lesion (2.1％),detection rate of proliferative polyps (20.3％),detection rate of Paris type 0-Ⅱ (38.0％),detection rate of NICE 1 type (pale lesion,22.2％),detection rate of polyps with a diameter<5 mm (30.5％) and the consistency rate of pathological biopsy (86.4％),specificity (84.7％) and sensitivity (88.2％) in the indigo carmine staining group were higher,and the differences were statistically significant (P<0.05).There was no statistical difference in the duration of mirror withdrawal between the white light endoscopy group and the indigo carmine staining group (t=1.407,P=0.160).Conclusion The endoscopic examination with indigo carmine staining has a higher detection rate for right hemicolonic polyp,and is easier to detect micropolyps and flat polyps with pale color.
