A Role of Defecography and Cinedefecography for The Diagnosis of Chronic Constipation

To assess the role of Defecography and Cinedefecography for the diagnosis of chronic idiopathic constipation. A retrospective study of 122 constipated patients (33 male, 89 female) of mean age 49.5±1.5 (11-84) years who underwent defecography and cinedefecography was done. Non-relaxing puborectalis syndrome, rectocele, rectal intussusception, and sigmoidocele were observed in 43(35%), 38(31%), 22(18%), and 9(7%) of the patients, respectively. Normal cinedefecography finding was observed in 31(25%) patients. More than one abnormal finding was found in 20(16%) patients. Incidence of non-relaxing puborectalis syndrome in male was higher than that in female (M: F=55:28 %, P < 0.01). In younger female patients group( age < 40 years; 33 patients), incidence of rectocele(46%), and non-relaxing puborectalis syndrome (36%) were higher than incidences of rectal intussusception (12 %) and sigmoidocele (6 %) (P < 0.005). In older female patients group( age ≥ 40 years; 56 patients), incidences of rectocele, non-relaxing puborectalis syndrome, rectal intussusception and sigmoidocele were 41, 23, 23, and 9 percents, respectively (P < 0.05). Defecography and cinedefecography were effective diagnostic tool for idiopathic constipation, so the radiological technologist should be interested in the knowledge and technique of this study.
