Background:Colonoscopy,regarded as the gold standard for detecting colorectal polyps,has a certain rate of missed diagnosis.Enhancing the polyp detection rate holds the promise of reducing the incidence of colorectal cancer.In recent years,electronic chromoendoscopy has been gradually gaining popularity.Optical enhancement(OE),which is the electron staining mode of Pentax endoscopy,and its impact on the polyp detection rate in patients with ulcerative colitis(UC)remains unclear.Aims:To investigate the effect of OE mode on polyp detection rate in patients with UC.Methods:A total of 233 UC patients who underwent colonoscopy at Xingtai People's Hospital in Hebei Province from July 2020 to April 2024 were enrolled.These patients were divided into the OE group and the High-definition white light(HDWL)group.The two groups were compared in terms of gender,age,Boston bowel preparation score(BBPS),withdrawal time,polyp detection rate,adenoma detection rate,polyp size,and polyp location.Results:There were no significant differences in gender,age,BBPS,and withdrawal time between the OE group and the HDWL group.When compared with the HDWL group,No significant differences in the polyp detection rate(24.66%vs.14.69%,P=0.071)and the adenoma detection rate(13.7%vs.6.99%,P=0.108)were found between the OE group and HDWL group.There was no significant difference in the detection rate of tiny polyps(with a diameter≤5 mm)between the OE group and the HDWL group(78.57%vs.79.41%,P=0.936).Also,there was no significant difference in the detection rate of proximal colon polyps(42.86%vs.41.18%,P=0.894).Moreover,no complications such as bleeding or perforation occurred during the colonoscopy in either group.Conclusions:During colonoscopy,compared with the HDWL mode,the OE mode does not significantly improve the polyp detection rate in UC patients.
