A new study, published in Colorectal Disease, examines histopathology changes after non-ablative radiofrequency to smooth muscle as delivered by Stretta therapy for gastroesophageal reflux disease and Secca therapy for fecal incontinence.
The study was performed on an animal model of fecal incontinence with three study arms — an experimental model of fecal incontinence with damage to the sphincter muscle, which remained untreated; a group with sphincter damage, treated with non-ablative radiofrequency; and a control group without a damaged sphincter and without treatment.
The study found that non-ablative radiofrequency improved the smooth-muscle sphincters of the GI tract as well as the skeletal muscle of the external anal sphincter.
