The purpose of this study was to assess the efficacy of percutaneous nerve evaluation (PNE) in women with faecal incontinence (FI) following obstetric anal sphincter injury and to relate the outcomes to baseline factors, with special emphasis on the extent of the sphincter defect.
This was a prospective study at a tertiary colorectal referral unit at the University Hospital of North Norway conducted from 2012 to 2014. Sixty-three women underwent a 3-week PNE using a tined lead and the Verify(®) external neurostimulator. The primary outcome was efficacy, defined as the percentage reduction in weekly FI episodes, and patients with a reduction of 50% or more were defined as responders. Baseline factors affecting the primary outcome were explored. Sphincter defects were classified with a validated three-dimensional endoanal ultrasound defect score.
Fifty-six (89%) of the 63 women were responders with a reduction in weekly FI episodes of 94.5%, from a median (interquartile range) of 4.8 (2.0-11.0) to 0.5 (0-2.0) (P
Fecal incontinence quality-of-life scale (FIQLS) is a condition-specific health-related quality-of-life questionnaire composed of four scales: lifestyle, coping/behaviour, depression/self-perception and embarrassment. It has been widely translated and used as an evaluation tool for patients with fecal incontinence. Our aim was to translate the FIQLS, and to test some of the psychometric properties of the Norwegian version of the questionnaire.
The FIQLS was translated to Norwegian, and administered to a sample of 76 patients (73 women) who completed the questionnaire at baseline and again after three weeks. In addition, the severity of incontinence was assessed by phone-interviews (St. Mark's score).
Three of four domains had good internal consistency in terms of Cronbach's alpha (.83-.91), the fourth (embarrassment) somewhat lower (.64). Stability over time was acceptable for all domains with ICC ranging from .74 to .86. Correlation with severity of incontinence (St. Mark's score) was medium to large for all four domains (-.46 to -.63) supporting the construct validity of the Norwegian FIQLS.
The Norwegian version of fecal incontinence quality-of-life scale has been successfully translated and tested.
