- Abstract: Objective To investigate the effect of endoscopic prebiopsy forceps on the detection rate of polyps in the right semicolon.Method Clinical data of 148 patients diagnosed and treated from March 2022 to December 2022 who were detected as polyps in the right semicolon by general electronic colonoscopy were collected,and clinical data of the patients who underwent endoscopic prebiopsy forceps were re-examined and the patients underwent endoscopic treatment within 1 month.The differences in general data,polyp number detected,polyp size,morphology and pathological diagnosis between the two groups were analyzed and compared.Results 168 polyps were detected in the right semicolon in the general colonoscopy group,and 41 polyps were missed in reexamination using endoscopic prebiopsy forceps,with a missed diagnosis rate of 19.62%.The detection rate of<5 mm polyps was higher in the endoscopic prebiopsy forceps group than that of general colonoscopy group,the difference was statistically significant(P<0.05).The polyps in the two groups were mainly wide-basal type,and the pathological properties were mainly tubular adenoma,there was no statistical significance among all groups(P>0.05).No complications such as bleeding and perforation occurred in the two groups.Conclusion Endoscopic prebiopsy forceps can significantly improve the detection rate of polyps in the right semicolon,in particular,the intraoperative search for disappeared preoperatively identified intestinal polyps,as well as smaller diameter intestinal polyps,which is worthy of further clinical promotion.
