This study aimed to determine the miss rate and risk factors for polyps, adenomas, and advanced adenomas in a population undergoing colonoscopy, as well as analyze the impact of colonoscopy with anesthesia on miss rate. Patient and lesion miss rates were calculated and compared, revealing factors such as lesion size, shape, and patient characteristics that were associated with missed lesions. Colonoscopy with anesthesia was found to reduce the polyp miss rate, with male and elderly patients being more likely to be missed during colonoscopy without anesthesia.
Objectives To systematically determine the miss rate and risk factors for polyps, adenomas and advanced adenomas in the same population, and to further analyze the impact of colonoscopy with anesthesia on miss rate. Methods We retrospectively analyzed the information of the patients undergoing the second colonoscopy within 1 year after their first. The patient and lesion miss rate were calculated. The patient and lesion features of missed lesion were compared with non-missed lesion. Finally, the patients were divided into anesthesia group and without anesthesia group, and the impact of colonoscopy with anesthesia on missed lesions was further analyzed. Results The patient miss rate of polyps, adenomas and advanced adenomas was 32.8, 25.6 and 10.4%, and the lesions miss rate was 19.6, 15.8 and 7.2%. In multivariable logistic regression analysis, lesion-related factors (large number of lesions, small lesion size, flat shape and location at the right colon) and patient-related factors (male, elder, abdominal symptoms, surgical history, diverticulum, colonoscopy without anesthesia and suboptimal bowel preparation) were found to be independently associated with missed polyps and adenomas (p < .05). Large number of lesions, flat shape and suboptimal bowel preparation were associated with missed advanced adenoma (p < .05). Colonoscopy with anesthesia can reduce the polyp miss rate (PMR) and male and elderly patients are more likely to be missed during colonoscopy without anesthesia. Conclusions Many factors of patients and lesions can affect the lesions miss rate. Colonoscopy with anesthesia can reduce the PMR and male and elderly patients are more likely to be missed during colonoscopy without anesthesia.
