实践证明,低位前切除术(LAR)的5年生存率与Miles＇术式无明显差别。我院1981年～1990年,10年间共行前切除吻合术(AR)179例。其中满5年的50例。年龄22岁～77岁,平均49.9岁。40岁以上占70％。上、中、下段癌分别占16％(8/50)、52％(26/50)、32％(16/50)。高位前切除占7.9％(6/50)、低位42％(21/50)、超低位 46％(23/50)。全部手法吻合,无手术死亡。生存率3年为70.4％,5年为56％。术后吻合口漏发生率18％。肛门功能满意。
Practice has shown that there is no significant difference between the five-year survival rate and Miles’ surgery for low anterior resection (LAR). In our hospital from 1981 to 1990, a total of 179 preoperative anterior resection and anastomosis (AR) were performed during the 10 years. Among them, 50 cases have been completed for 5 years. Age 22 to 77 years, average 49.9 years old. More than 40 years old accounted for 70%. Cancers in the upper, middle, and lower segments accounted for 16% (8/50), 52% (26/50), and 32% (16/50), respectively. The anterior high excision accounted for 7.9% (6/50), the low 42% (21/50), and the ultra low 46% (23/50). All the methods were consistent and no operative death occurred. The survival rate was 70.4% for 3 years and 56% for 5 years. The incidence of anastomotic leakage after surgery was 18%. Anal function is satisfactory.
