Abstract

Objective This study aims to investigate the value of link color imaging (LCI) compared with Narrow Band Imaging (NBI) in the diagnosis of minute serrated lesions in the colon and rectum. Methods A prospective study was conducted from January to July 2024, including 664 patients who underwent colonoscopy at the Second Affiliated Hospital of Wannan Medical College. Patients were randomly divided into the LCI group and the NBI group. The study compared the detection rates of minute polyps in the colon and rectum, the detection rates of polyps in different parts of the intestine, the detection rates of different Sanada typing of polyps, and the corresponding pathological comparison between the two groups. Results The overall detection rate of minute polyps in the LCI group was higher than that in the NBI group (P<0.05), and the detection rate of minute polyps in the right hemicolon was higher in the LCI group than in the NBI group; especially in the detection rate of Sanada type I lesions, the LCI group was significantly higher than the NBI group (P<0.001). In terms of pathological results, the number of inflammatory polyps and sessile serrated lesions detected in the LCI group was higher than that in the NBI group (P<0.05). Conclusion LCI technology has a significant advantage in improving the detection rate of minute polyps in the colon and rectum, especially minute polyps in the right half of the colon and sessile serrated lesions, which has important clinical significance for the prevention of colorectal cancer.
