１９８２年１月至１９９７年１２月共行直肠癌Ｍｉｌｅｓ手术１７９例。其中１３６例于骶前腔置两根硅胶双套管引流。会阴切口Ⅰ期愈合率达９４％。术后平均住院时间２２天。明显优于单腔和香烟凡士林纱条引流组。本文还就Ｍｉｌｅｓ手术会阴切口的不同处理方法和双套管的特点进行了讨论。认为盆底腹膜缝合，骶前腔硅胶双套管引流和Ⅰ期缝合会阴切口是预防Ｍｉｌｅｓ手术会阴部伤口感染较为有效的措施
From January 1982 to December 1997, 179 patients underwent Miles surgery for rectal cancer. One hundred and thirty-six cases received two silicone double cannula drainages before the fistula. Perineal incision healing rate of 94%. The average hospital stay was 22 days after surgery. It is significantly better than the single chamber and Cigarette Vaseline gauze drainage group. This article also discusses the different treatment methods of the perineal incision and the characteristics of the double cannula in the Miles operation. It is considered that the pelvic floor peritoneum suture, double silicone tube drainage in the anterior tibial cavity, and the first-stage suture perineal incision are effective measures to prevent wound infection in the perineum of Miles.
