Abstract: Objective To investigate the dynamic abnormality of colon and anorectum in elderly patients with chronic functional constipation(CFC). Methods Forty-two elderly patients with CFC and twenty elderly healthy controls were selected. Total and segmental colonic transit time(CTT) were assessed radiographically by using oral radiopaque markers. Eight-lead water perfusion pressure measurement system and balloon were used to test the pressure and the perception threshold values of anus and rectum. Results (1) Total colonic transit time (TCTT) and sigmoid-rectum transit time (SRTT) were (49.0±16.4) h and (20.1±13.5) h in elderly patients with CFC, which were significantly prolonged compared with the controls [(25.2±7.7) h and (7.8±4.1) h, t=6.16 and 3.97,both P<0.05]. (2) The pressure of anal canal during defecation was (39.6±15.7) mmHg in elderly patients with CFC and (17.6±9.3) mm Hg in controls (t=5.79, P
