Abstract:
Objective To investigate the impact of linked color imaging(LCI)combined with a transparent cap on the detection rate of colorectal sessile serrated lesion(SSL).Methods A total of 492 patients who underwent colonoscopy the First People's Hospital of Huzhou from February 2024 to January 2025 were randomly assigned to three groups:White light imaging(WLI)group,LCI group,and LCI combined with transparent cap group,with 164 cases in each group.The general clinical data,cecal intubation time(CIT),withdrawal time,SSL detection rate,small(≤5mm)SSL detection rate,and proximal colon SSL detection rate were analyzed and compared among three groups.Results There were no significant differences in general clinical data,CIT,or withdrawal time among three groups(P>0.05).Statistical analysis revealed that the SSL detection rates for WLI group,LCI group,and LCI combined with transparent cap group were 6.10％,12.20％,and 18.90％,respectively;In the proximal colon,the SSL detection rates for WLI group,LCI group,and LCI combined with transparent cap group were 3.66％,9.15％,and 16.46％,respectively;For small(≤5mm)SSL,the detection rates were 1.22％,2.44％,and 7.32％in WLI group,LCI group,and LCI combined with transparent cap group,respectively also showing statistically significant differences(P<0.001).Conclusion Colonoscopy using LCI combined with a transparent cap significantly improves the detection rate of SSL,particularly for small SSL.
