Abstract:
Objective To explore the factors affecting the detection rate of colorectal polyps in repeated colonoscopy. Methods 400 patients from February 2016 to February 2017 were selected for repeated colonoscopy. Strict control of the objective factors in colonoscopy (endoscopic experience, endoscopic mode of operation, retraction time and the degree of intestinal cleaning, etc.), the number, size, shape, location and pathological types of polyps detected in the 400 randomly selected patients were compared between the two examinations, Logistic regression analysis was used to find the independent influencing factors of missed diagnosis. Results A relatively high missed rate could be happened in multiple polyps, small polyps ( ≤ 5 mm), stepless polyps, sigmoid polyps, transverse colon polyps and ascending colon polyps (all P < 0.05), and low missed rate in pathological types (P > 0.05). Logistic regression analysis showed that the number, size, shape and location of polyps were independent factors (all P < 0.05). Conclusion The number, size, shape and location of colorectal polyps are all important factors influencing the detection rate. With the advancement of clinical technology, it is possible to use the new technique to improve the detection rate of polyps.
