Feasibility of two-man performance switching to one-man performance in colonoscopy

Objective:To investigate the feasibility of two-men colonoscopy performance switching of colonoscopic technique to one-man performance,and to assess its advantages.Methods:All the patients undergoing one-man colonoscopy performance in our hospital were enrolled in this study.The success rate,cercal intubation rate,time required for cercal intubation and incidence of complications were observed.Results:The success rate of one-man colonoscopy performance was 96.3%,and the mean time for examination was between 5 to 10 min.None of the patients experienced lesion residue,asenterobrosis or enterorrhagia.Conclusions:Our study suggests that one-man colonoscopy performance is simple and safe,causing less discomfort or pain for patients.This operation is clinically promising and worth popularizing.
