Abstract
A series of anal fistulae is presented in which a high proportion were anterior horseshoe fistulae. The incidence of this type of fistula in this series is higher than that previously reported. It can be recognised by a study of the position of the track by palpation, and the distance from the anal verge of the external opening. A meticulous dissection at operation is required. In order to get good results it is important that this clinical entity be recognised and managed with the same care and attention that is required for a posterior horseshoe fistula.
