The Fenix System for Fecal Incontinence: An Overview and Surgical Demonstration

Abstract

Study ObjectiveThis video shows a new technique for the surgical management of fecal incontinence using the Fenix Continence Restoration System (TORAX Medical Inc, Shoreview, MN) in 2 patients. DesignA step-by-step explanation of the video using videos and pictures (educational video) for surgeons (Canadian Task Force classification III). SettingThe use of the Fenix System received United States Food and Drug Administration approval under a humanitarian device exemption and can be used with institutional review board approval in patients who have failed previous medical and surgical management of fecal incontinence. The device is a small, flexible band of interlinked titanium, magnetic beads on a titanium string that is placed using a perineal approach around the anal canal. Increased intra-abdominal pressure opens the beads to allow for the passage of stool. InterventionsPlacement of the device was performed in 2 patients. Case 1 is a 63-year-old woman with a long-standing history of fecal incontinence who failed sphincteroplasty, sacral neuromodulation, and an artificial sphincter cuff and pump. Case 2 is a 60-year-old woman with a long-standing history of fecal incontinence secondary to radiation therapy for rectal cancer who failed physical therapy and sacral neuromodulation. ConclusionBoth Fenix Continence Restoration Systems were placed successfully. Long-term postoperative effectiveness is currently being evaluated.
