Trial Outcomes & Findings for Efficacy and Mechanisms of Pharmacologic Treatment of Fecal Incontinence (NCT NCT00727649)
NCT ID: NCT00727649
Last Updated: 2015-04-01
Results Overview
After consent, 7-day bowel diary was assessed at baseline (2-week visit), during the last week of the 4-week intervention (6-week visit), during the second week of the 2-week wash-out period at 8-weeks, and during the last week of the second 4-week intervention (12 weeks). The mean number of total fecal incontinence episodes from a 7-day bowel diary from each time point was compared between the groups.

PRIMARY outcome
Timeframe: 4 weeksAfter consent, 7-day bowel diary was assessed at baseline (2-week visit), during the last week of the 4-week intervention (6-week visit), during the second week of the 2-week wash-out period at 8-weeks, and during the last week of the second 4-week intervention (12 weeks). We compared the percentage of the total number of fecal incontinence episodes over the total number of bowel movements from a 7-day bowel diary from each time point between the groups.

SECONDARY outcome
Timeframe: baseline, 4 week and 12 weeksThe patient-reported symptoms severity score, the Fecal Incontinence Severity Index (FISI), has 4 questions about the frequency of gas, mucus, liquid stool, and solid stool incontinence. Responses are weighted based on the patient rating of severity and a total score is calculated (range 0-61) with higher scores indicating a greater severity of symptoms.
