Fecal Incontinence
Conditions
Keywords
Device study, Pelvic floor weakness, Fecal incontinence
Brief summary
The study purpose is to gain experience with the TOPAS system, a minimally- invasively delivered self-fixating mesh for the treatment of pelvic floor weakness in women with symptoms of moderate fecal incontinence
Detailed description
This is a multi-center study under a common protocol. Approximately 20-30 patients will be enrolled across 5 sites in the U.S. The study population is females at least 21 years of age who have attempted but have not been satisfied with conservative therapy for their fecal incontinence symptoms. The study follow-up is two years.
Interventions
A mesh sling permanently implanted to increase pelvic floor support

Eligibility
Inclusion criteria
* Females at least 21 years of age who have evidence of pelvic floor weakness * Females who attempted but not been satisfied with conservative therapies such as dietary changes, dietary bulking agents, biofeedback, etc. * Subjects, who have an external anal injury, must have some voluntary sphincter control
Exclusion criteria
* Subjects who are unwilling or unable to sign an Informed Consent form * Subjects who are currently pregnant or considering future child-bearing * Subjects who are contraindicated for surgery * Subjects who are allergic to polypropylene mesh * Subjects who are enrolled in a concurrent clinical trial * Subjects with previous implantation of mesh or trauma to the pelvic area * Subjects who engage in anal receptive intercourse * Subjects with a significant evacuation disorder such as chronic constipation * Subjects with Crohn's Disease, ulcerative colitis or chronic diarrhea as the primary cause for fecal incontinence * Subjects who had a hysterectomy within 6 months prior to enrollment * Subjects with vaginal prolapse that passes the hymen * Subjects with complete rectal prolapse * Subjects with a history of pelvic radiation that compromises the anal canal * Subjects who have psychiatric disturbance or debilitation as a possible cause for fecal incontinence * Subjects with a neurological disorder such as amyotrophic lateral sclerosis, multiple sclerosis, or brain tumor as a possible cause for fecal incontinence symptoms * Subjects with an active pelvic infection or a recto-vaginal fistula * Subjects who have not had a negative screening exam for colon cancer within 10 years of enrollment * Subjects who have other inappropriate conditions as determined by the physician

| Fecal Incontinence Symptoms as Measured by Symptom Severity Scale in Fecal Incontinence | Baseline (pre-treatment), 6 Week, 3 Month, 6 Month, 12 Month and 24 Month post-treatment | The Symptom Severity Scale in Fecal Incontinence is a subject-completed questionnaire that asks about the symptoms of fecal incontinence in the following areas: frequency, stool composition, stool amount, and degree of urgency. The total score is measured on a 0 (best) to 13 (worst) scale. Scores of 1-6, 7-10, and 11-13 were categorized as mild, moderate, and severe fecal incontinence, respectively. |
| Quality of Life Assessment as Measured by Fecal Incontinence Quality of Life | Baseline (pre-treatment), 3 Month, 6 Month, 12 Month and 24 Month post-treatment | The Fecal Incontinence Quality of Life Assessment is a subject-completed questionnaire. It is measured in each of four areas of depression (7 items), lifestyle (10 items), coping (9 items), and embarrassment (3 items). Area scores are measured on a 1 (worse) to 4 (best) scale and are each the average of their component individual item scores measured on the same scale. |
| Pain Intensity as Measured by the Pain Intensity Scale | Baseline (pre-treatment), 6 Week post-treatment | The Pain Intensity Scale is a subject completed questionnaire. Scores are measured on 0 (no pain) to 10 (worst possible pain) scale. |

An overall Wexner Score is computed from these five components and a score of 0 means perfect control and 20 means complete incontinence. |
