通过对161例低位直肠癌下缘距肛缘距离和Dukes分期与保肛术式的不同,选择了Miles,低位吻合,超低位吻合,Park’s,Bacon 5种术式,并且对此进行了排便功能和5年生存率和局部复发率的随访。结果是低位直肠癌的保肛率达58.39%。其中,低位吻合9例,超低位吻合48例,Park’s手术25例,Bacon手术13例。手术死亡率2.1％(2例),吻合口瘘3例(3.19%),吻合口狭窄13.8％。术后排便功能优良率:低位:100％,超低位吻合:97.91％,Park’s手术:88%,Bacon手术.53.33％。5年生存率和局部复发率:低位吻合:82％、0％;超低位吻合78.9%、4.16%;Park’s手术:69.1%、13%;Bacon手术:63.1%、12％。
By using different distances between the lower edge of the rectum and the Dukes staging and sphincter preserving operation in 161 patients with low rectal cancer, Miles, low anastomosis, ultralow anastomosis, Park’s, Bacon were selected and defecation was performed. Follow-up of 5-year survival rate and local recurrence rate. The result is an anus-preserving rate of 58.39% for low rectal cancer. Among them, there were 9 cases with low anastomosis, 48 cases with ultralow anastomosis, 25 cases with Park’s surgery, and 13 cases with Bacon surgery. Surgical mortality rate was 2.1% (2 cases), anastomotic leakage was 3 cases (3.19%), and anastomotic stenosis was 13.8%. Postoperative defecation function was excellent: low: 100%, ultra-low anastomosis: 97.91%, Park’s surgery: 88%, Bacon surgery .53.33%. 5-year survival rate and local recurrence rate: low anastomosis: 82%, 0%; ultra-low 78.9%, 4.16%; Park’s surgery: 69.1%, 13%; Bacon surgery: 63.1%, 12%.
