本文介绍一种治疗低位直肠癌和肛管癌的新手术方式。该术式按照腹会阴联合切除术(Miles 术)的要求,广泛切除肿瘤,但术后人工肛门置在原肛门处,用臀大肌肌索成形重建肛门括约肌,以达到控制排便。作者用该术式治疗了10例病人,除1例失败,余9例术后经短期观察,便前均有下腹隐痛,肛口胀痛等便意感。重建的肛门括约肌均有不同程度的收缩力和控制排便的能力。
This article describes a new surgical approach to treat low rectal cancer and anal canal cancer. According to the requirements of abdominoperineal resection (Miles operation), the operation method was extensively used to remove the tumor, but the artificial anus was placed at the original anus and the anal sphincter was reconstructed with gluteus maximus myocutaneous suture to achieve control of defecation. The authors used this technique to treat 10 patients. Except one patient failed, the remaining 9 patients had short-term observation after operation, and both had lower abdominal pain, anal pain, and other sensations. The reconstructed anal sphincter has varying degrees of contractility and ability to control defecation.
