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 COMPARATOR

Patients 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.

Drug: Botulinum Toxin-A

Normal saline

PLACEBO COMPARATOR

Patients will receive normal saline (placebo) injected in the puborectalis muscle and external anal sphincter.

Drug: Normal Saline

Interventions

100 Units diluted in a 5 cc syringe at a concentration of 20U/mL

Also known as: Botox
Botulinum Toxin-A

Dispensed in a 5 cc syringe

Also known as: 0.9% Sodium Chloride
Normal saline

  • Failure of treatment with 2 conservative measures which may be as follows:
