Conditions

Constipation Aggravated, Pelvic Floor; Incompetency

Brief summary

Supporting the pelvic floor can reduce symptoms of constipation in patients with refractory constipation due to pelvic floor laxity and excessive perineal descent by means of a modified toilet seat, known as the Bottom's Up.

Detailed description

Efficacy and safety of a unique pelvic floor support device that fits into the Radiology defecography commode will be tested. Patients with refractory constipation due to known pelvic floor laxity and/or excessive perineal descent will be examined without, then with the device in place. Patients will complete questionnaires pertaining to device safety and efficacy before and after using the device. Radiographic images to document efficacy of support plus adequate emptying will be acquired during the study resulting in very low dose radiation exposure.

Secondary

MeasureTime frameDescription
Sense of Stainingpost-defecography test, approximately 1 daySense of straining was measured using the self-reported answer to the modified Pelvic Floor Distress Inventory Questionnaire-20 (PFDI-20) question of 'Did you need to strain hard to empty your rectum'. The Likert scale questionnaire scores ranged from 0-10 where 0 = No, not at all and 10 = Yes, quite a bit.
Ease of Evacuationpost-defecography test, approximately 1 dayEase of evacuation was measured using the self-reported answer to the modified Pelvic Floor Distress Inventory Questionnaire-20 (PFDI-20) question of 'Did you experience pain/discomfort when you emptied your rectum'. The Likert scale questionnaire scores ranged from 0-10 where 0 = No, not at all and 10 = Yes, quite a bit.
