PURPOSE: To evaluate colonic transit time (CTT) in patients with spastic pelvic floor syndrome (SPFS)diagnosed by defecography and compare the findings with those of patients with normal defecography. MATERIALS AND METHODS: Over a recent 15-month period, 140 patients underwent both defecography and CTT test because of chronicidiopathic constipation. Of these, 54 with SPFS diagnosed by defecography and 49 controls with normal defecographywere included in our study. CTT testing involved the radiopaque marker method. Subjects ingested 24 markers at9:00AM on three consecutive days and a plain film of the abdomen was obtained on day 4. We calculated total andsegmental CTT, and compared CTT test findings in the two groups. RESULTS: Delayed total CTT was found in 35% ofpatients (19/54) with SPFS. Segmental CTT in the right, left and rectosigmoid colon was delayed in 19% (10/54),44% (24/54), and 31% of cases(17/54), respectively. Total CTT was delayed in 31% of patients(15/49) with normaldefecography. In this group, segmental CTT in the left colon was delayed in 39% of cases. CONCLUSION: There was nosignificant difference in CTT findings between the SPFS and normal groups on defecogram.
