A control study of CT colon scans in normal adults and patients with intractable constipation after air enema for measuring colon length / 实用放射学杂志

Objective To investigate the difference of colon length between patients with intractable constipation and normal peo-ple.Methods 40 patients with intractable constipation and 35 cases of normal control group received air enema CT scan,post-pro-cessing techniques-curved planar reformation and volume rendering were used to measure the length of colon.Results Colon length of normal people and constipation patients were (1 230±33)mm and (1 605±47)mm,respectively.There was significant difference between normal people and constipation patients (t=163,P=0.015).Conclusion CT air enema technique can be used to measure the length of colon obj ectively for diagnosing and treating redundant colon.
