Idiopathic chronic anal fissure is believed to be a consequence of a traumatic acute anodermal tear followed by recurrent inflammation and poor healing due to relative tissue ischaemia secondary to internal sphincter spasm. This pilot trial compared the efficacy of a novel manufactured ano-coccygeal support attached to a standard toilet seat (Colorec) to the standard procedure of lateral internal sphincterotomy (LIS) for chronic anal fissure.
