Radiofrequency energy delivery to the anal canal: is it a promising new approach to the treatment of fecal incontinence?

Background: The present study was conducted to assess the efficacy and safety of the delivery of radiofrequency energy to the anal canal (the SECCA procedure). Methods: Eight patients with fecal incontinence underwent the SECCA procedure. The Fecal Incontinence Severity Index (FISI) score and the Fecal Incontinence-related Quality of Life (FIQL) scale were completed at baseline and after the procedure. Anorectal manometry and endoanal ultrasound also were conducted. Results: Seven of the 8 patients were women, and the median age of the patients was 59 years (range, 28-73 y). The mean FISI score and all of the parameters in the FIQL scale with the exception of the embarrassment scale measured at 6 months after the procedure was not improved significantly. We observed no changes in the anal manometry and endoanal ultrasound parameters. Complications associated with the procedure developed in 7 of the 8 patients, including anal bleeding, anal pain, and anal mucosal discharge. Conclusions: The FISI score and FIQL scale were not improved significantly after the SECCA procedure, and considerable complications were associated with the procedure.
