Drainage of various types of perirectal abscesses can be facilitated by the use of a rectal hook, allowing many of these infections to be easily handled in the outpatient setting. Several types of abscesses, including ischiorectal and pelvirectal abscesses, although usually originating at the crypts of Morgagni, cannot be drained adequately by this technique. Differential diagnosis of anal pain is considered.
使用直肠钩有助于各种类型的直肠周围脓肿引流，使许多此类感染在门诊环境中易于处理。几种类型的脓肿，包括坐骨直肠窝脓肿和盆腔直肠脓肿，尽管通常起源于莫尔加尼隐窝，但通过这种技术无法充分引流。本文考虑了肛门疼痛的鉴别诊断。
