Abstract:
Objective To investigate the influential factors for the colonoscopic polyp detection rate (PDR) and adenomade detection rate(ADR) in high-risk population in community colorectal cancer screening.Methods Data of patients who were determined as high-risk population in community colorectal cancer screening tests and received colonoscopy in the Digestive Endoscopic Center of Tongji Hospital from May 2014 to November 2014 were collected.PDR and ADR were calculated by different genders, ages, history of abdominal operation, anesthesia assistance, quality of bowel preparation and experience of operators.Thex2 test and logistic regression analysis were used to compare the PDR and ADR between different groups.Results A total of 417 patients received complete colonoscopies.The total PDR was 35.25％.Univariate analysis revealed that gender (OR =2.298,95％ CI: 1.525-3.463), history of abdominal operation (OR =0.596,95％CI:0.390-0.910), anesthesia assistance (OR =1.864,95％ CI: 1.086-3.200) and quality of bowel preparation were significantly associated with PDR while multivariate analysis revealed that only gender, history of abdominal operation and quality of bowel preparation were independent influential factors for PDR.The total ADR was 30.22％.Like PDR, univariate analysis revealed that gender(OR =2.113,95％CI: 1.382-3.229), history of abdominal operation(OR =0.604,95％ CI:0.387-0.941), anesthesia assistance(OR =2.344,95％ CI: 1.283-4.281) and quality of bowel preparation were significantly associated with ADR.However, multivariate analysis revealed that only gender, history of abdominal operation and quality of bowel preparation were independent influential factors for ADR.Conclusion For patients who were highrisk in community colorectal cancer screening, men have greater risk to develop polyps and adenomas than women.Colonoscopy should be more careful in patients with history of abdominal operation, for quality of bowel preparation is directly related to PDR and ADR.
