Abstract：Objective: To investigate the value of colonoscopy combined with transparent cap. Methods: Totally 248 patients were selected from all the patients that took examinations in center of GI endoscopy between January and November in 2016. The chosen patients were divided randomly into the observation group(124 cases) and the control group(124 cases). The patients in the observation group were administrated transparent cap colonoscopy and those in the control group were administrated conventional colonoscopy. All patients were operated in non anesthetic state by one digestive endoscopic doctor. The two methods were compared by success rate, cecal intubation time, Numeric Rating Scale(NRS) and polyp detection rate. The influence factors of cecal intubation time were analyzed by gender, age, history of abdominal operation and chronic constipation. Results: The success rate of colonoscope of observation group and control group were 96.77% and 89.52%; cecal intubation time were (436.19±184.10)seconds and (569.57±217.15)seconds; the polyp detection rate were 42.74% and 28.23%, and the NRS were (4.06±1.84) and (5.89±2.12), respectively. There was significant difference between the two groups(P<0.05). No complication was observed in all patients. In all the influence factors of cecal intubation time, there were significant differences regarding to gender, age, history of abdominal operation and chronic constipation(P<0.05). Conclusion: The colonoscopy combined with transparent cap is an examination with high success rate, short cecal intubation time, high polyp detection rate and less pain of patients while gender, age, history of abdominal operation and chronic constipation are main factors that might result in longer cecal intubation time.
