ABSTRACT

Objective To explore the applied value of static and dynamic of virtual defecography technology in the etiological diagnosis of constipation.Methods 50 patients with constipation were included.Conventional cleaning enema was performed firstly.Then they were injected the virtual defecography agentwith lateral position,filling the rectum,sigmoid and descending colon.Thirdly,siting on the qualities commode,adjusting height coincides with the left and right femur,displaying the pubic symphysis and coccyx dynamic acquisition image acquisition with the speed of 4/s,the dynamic changes of the rectum and anal canal were analyzed and measured.Results Among 50 patients,32 cases with rectocele,1 case with rectal bend,2 cases with anal canal stenosis,7 cases with rectal prolapse,4 cases pelvic floor spasm syndrome,and 4 cases with no cause.Conclusion Static and dynamic virtualdefecography was an important method in the etiological diagnosis of patients with constipation.
