摘 要：AIM:To assess the value of computed tomography(CT)for diagnosis of synchronous colorectal cancers(SCRCs)involving incomplete ***:A total of 2123 cases of colorectal cancer(CRC)were reviewed and divided into two groups according to whether a complete or incomplete colonoscopy was *** results and final histological findings were compared to calculate the sensitivity and specificity associated with CT for detection of SCRCs following complete vs incomplete *** affecting the CT detection were also ***:Three hundred and seventy-four CRC patients underwent incomplete colonoscopy and 1749received complete ***-six cases of SCRCs were identified by CT,and 36 were *** the incomplete colonoscopy group,the sensitivity and specificity of CT were 44.8%and 93.6%,*** positive and negative predictive values were 23.6%and 95.0%,*** contrast,the sensitivity and specificity of CT for the complete colonoscopy group were 68.3%and 97.0%,while the positive and negative predictive values were 22.2%and 98.7%,*** both groups,the mean maximum dimension of the concurrent cancers identified in the CT-negative cases was shorter than in the CT-positive cases(incomplete group:P=0.02;complete group:P0.01)Topographical proximity to synchronous cancers was identified as a risk factor for missed diagnosis(P=0.03).CONCLUSION:CT has limited sensitivity in detecting SCRCs in patients receiving incomplete *** with risk factors and negative CT results should be closely examined and monitored.
