许多报告均提示年龄不再是有关结直肠切除术后死亡率和长期生存率的预后因素。作者自1985年以来已为27例62岁以上的低位直肠癌施行切除手术和经肛管的结肠肛门吻合(CAA),对其中22例进行分析(男8例,女14例,年龄72±6.8岁)。Dukes分类,计A级8例、B级8例、C级4例和D级2例。肿瘤下缘与齿线相距3～8 cm,其中18例不足6 cm。术前灌肠2次,麻醉时和术后24小时各给头孢甲氧噻吩和灭滴灵静脉注射各1次。游离乙状结肠和左侧结肠直至脾曲,如见明显动脉血管硬化,不结扎
Many reports suggest that age is no longer a prognostic factor for mortality and long-term survival after colorectal resection. Since 1985, the authors have performed excision and colon anal anastomosis (CAA) for 27 cases of low rectal cancer over 62 years of age, and analyzed 22 cases (8 males and 14 females, age 72±6.8). year old). Dukes classification included 8 cases of A grade, 8 cases of B grade, 4 cases of C grade, and 2 cases of D grade.
