The main doubt reducing enthusiasm for the radiofrequency remodeling technique (secca) was based on lack of physiological studies, which may explain the possible pathomechanism of improvement of symptoms. 20 fecal incontinence (FI) patients (6 male and 14 female, mean age 58 ranged 41-78 years) have been enrolled into the study. The standard technique and secca device was used (Curon Medical, Freemont, CA USA). The following parameters were evaluated at baseline, 3, 6, 12, 24 and 36 months after the procedure: continence (Jorge&Wexner, FISI scores), improvement (FIQL), rectalelectro- and thermosensitivity, barostat, anal manometry. Three mildcomplications were observed: submucosal hematoma, superficial lesion of mucosa and fever between 3rd and 5th postoperative day; they resolved spontaneously. QoL improved significantly in all measures: life style, coping,depression and embarrassment. Jorge&Wexner Incontinence Scale decreased significantly. BAP and SAP improved. The effectiveness of Secca procedure is related to restored anorectal sensitivity and recto-anal coordination, however effect on IAS morphology and function is also detectable. It reduces the frequency and severity of FI symptoms, and improves patient’s quality of life.
