The special and highly complicated anatomy of the continence organ is the basis for surgery in the perineal region and in the region of anus and rectum. The rectal cavernous body, the sphincter ani internus, which is aganglionic, as well as the asymmetry of the female external sphincter muscle, are new facts which must be given attention in respect of pathogenesis and therapy of many diseases occurring in this region. The article discusses piles, anorectal abscesses and fistulas, prolapse of the rectum and rectal cancer under these special aspects.
控尿器官特殊且高度复杂的解剖结构是会阴区域以及肛门和直肠区域手术的基础。直肠海绵体、无神经节的肛门内括约肌，以及女性外括约肌的不对称性，是在该区域发生的许多疾病的发病机制和治疗方面必须予以关注的新情况。本文从这些特殊方面探讨了痔疮、肛管直肠周围脓肿和肛瘘、直肠脱垂以及直肠癌。
