[Initial response to topical diltiazem can predict outcome of chronic anal fissure].

Introduction: In the last few years, the medical treatment of chronic anal fissure (chemical sphincterotomy) has been introduced as a consequence of the morbidity attributed to surgical sphincterotomy. However, medical treatment has two disadvantages: moderate effectiveness (between 30% and 80%) and the need for treatment to be prolonged for more than 8 weeks.
