A Study of Defecation Type by Defecograpy and CTTS

Purpose : This study is to find a mutual relation between the defecography and CTTS for diagnosis of chronic idiopathic constipation. Materials and methods : 148 patients, who have amount of injection and evacuation in taking defecography, was examined the defecography and CTTS. The finding of defecography was divided into five types including normality (type I), hypertonic lower anal sphincter (HLAS; Type Il), dyskinetic puborectal sling (DPS; Type III), spastic pelvic floor syndrome (SPFS; Type IV), and others (Type V ). Also that of CTTS was divided into four types including normality (type i ), colonic inertia (CI; Type ii), pelvic outlet obstruction (POO; Type iii), and hindgut dysfunction (HD; Type iv). Results : In the defecography, evacuation rate of 80% or more was in 51(34.5%), the lowest evacuation rate was in type IV(24.6%). The evacuation rate of finding of normality in the two study was 78.9%. The lowest evacuation rate was in type IV(52.5%) of type iii, and the highest evacuation rate was in type V(97.7%) of type iii. 8 patients had a finding of normality in the CTTS was included Type V of the defecography. Conclusion : The defecography and CTTS for diagnosis of chronic idiopathic constipation have to be examined together, because the two are complementary relation.
