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.
本文展示了一系列肛瘘病例，其中大部分是前马蹄形肛瘘。该系列中此类肛瘘的发病率高于先前报道。通过触诊研究瘘管位置以及外口距肛缘的距离可识别该类型肛瘘。手术时需要进行细致的解剖。为了取得良好效果，认识到这种临床实体并给予与后马蹄形肛瘘相同的谨慎关注进行处理非常重要。
