A technique is described for examining patients with perianal sepsis in the acute stage in which with an anal retractor in place the abscess is pressed to watch for pus coming out of the anal canal. The fistulous tract if present can be diagnosed and satisfactorily treated. As a result of these and other studies a number of anterior horseshoe fistulae have been found both in acute and non acute patients. Anterior horseshoe fistulae should be suspected to exist if a patient with an opening of the fistula anterior to the line drawn coronally through anal canal has such an opening more than 2.5 cm away from the anal verge or if there are multiple openings. In recurrent apparently straight forward anterior fistulae, anterior horseshoe fistula should be suspected to exist.
本文描述了一种用于检查急性期肛周脓毒症患者的技术，即在使用肛门牵开器的情况下按压脓肿，观察是否有脓液从肛管流出。若存在瘘管，则可进行诊断并得到满意治疗。通过这些及其他研究，在急性和非急性患者中均发现了一些前马蹄形肛瘘。如果肛瘘开口位于经肛管冠状线前方且距离肛缘超过2.5厘米，或者存在多个开口，则应怀疑存在前马蹄形肛瘘。在复发性看似简单的前肛瘘中，也应怀疑存在前马蹄形肛瘘。
