Six percent of the anorectal abscesses drained last year at the Naval Regional Medical Center, Portsmouth, Va, were of the high intramuscular variety. High intramuscular perianal abscesses may be difficult to diagnose because of the lack of external signs. It is important that a patient with unexplained anal pain be examined, under anesthesia if necessary. When a high intramuscular abscess is found, it is best drained into the anal canal rather than through a perianal skin incision.
去年在弗吉尼亚州朴茨茅斯海军地区医疗中心引流的肛门直肠脓肿中，6% 是高位肌内型。由于缺乏外部体征，高位肌内型肛周脓肿可能难以诊断。对有不明原因肛门疼痛的患者进行检查很重要，必要时在麻醉下检查。当发现高位肌内脓肿时，最好引流至肛管，而不是通过肛周皮肤切口引流。
