Hello. THD GatekeeperThe new THD product for the treatment of fecal incontinence is a revolution in this field and follows the THD philosophy of providing minimally invasive and safe procedures. Sterile THD Gatekeeper prostheses are inserted between external and internal anal sphincters. Over 24-48 hours the prostheses expand in size, optimizing the "bulking effect". believe that this procedure is something tike the Solesta injections. But this procedure sounds to be more processing.If the problem of the gas incontinence is in the internal anal sphincter I suppose that this may help us.
