Outcome Measures
Primary Outcomes (1)
Changes in the Altomare Obstructed Defecation Syndrome- Score (ODS-S) and Patient Assessment of Constipation- Quality of Life Score (PAC-QoL)
The primary outcome measure will be the change from baseline in the sum of ODS-S and PAC-QoL at 1 month after the Botox injection. This measures the symptomatic improvement in ODS. ODS (altomare obstructed defecation syndrome score) scores range from 0 (minimum) to 31 (maximum) where 31 is the most severe (worse outcome) and 0 is no symptoms (better outcome). The scale for PAC-QoL (Patient Assessment of Constipation- Quality of life score) is a minimum of 0 and a maximum of 112 where 0 is highest quality of life (better outcome) and 112 is lowest quality of life (worse outcome) Larger number for change would suggest a better outcome
Baseline, 1 month after injection
Secondary Outcomes (9)
Changes in the Altomare ODS Score (ODS-S)
Assessed at baseline, 1, 3, 6 and 12 months after injection and value compared from baseline to 12 months
Changes in the Patient Assessment of Constipation- Quality of Life Score (PAC-QoL)
Assessed at baseline, 1, 3, 6 and 12 months after injection and value compared from baseline to 12 months
Changes in Health-Related Quality of Life
Baseline, 1, 3, 6 and 12 months after injection and value compared from baseline to 12 months
Changes in Cleveland Clinic Fecal Incontinence Score (CCFI)
Assessed at baseline, 1, 3, 6 and 12 months after injection and value compared from baseline to 12 months
Changes in Fecal Incontinence Quality of Life Scale (FIQoL)
Assessed at baseline, 1, 3, 6 and 12 months after injection and value compared from baseline to 12 months
- +4 more secondary outcomes
Study Arms (2)
Botulinum Toxin-A
ACTIVE COMPARATORPatients will receive Botulinum Toxin-A (Botox) injected in the puborectalis muscle and external anal sphincter. We will use 100 units of Botox, a dose with a good safety profile that has been proven to work in previous studies performed in adults.
Normal saline
PLACEBO COMPARATORPatients will receive normal saline (placebo) injected in the puborectalis muscle and external anal sphincter.
Interventions
100 Units diluted in a 5 cc syringe at a concentration of 20U/mL

- Failure of treatment with 2 conservative measures which may be as follows:
- laxative (osmotic or stimulant) for 2 weeks
- fiber supplement for one month
- And/or trial of biofeedback for at least 4 sessions
