直肠中下段癌采用吻合器行直肠切除后端端吻合并保留肛门的手术有所增多。理论上说,这种手术可因盆腔组织清除不彻底而易致复发。为此,作者等对采用吻合器施行直肠癌前位切除而获随访逾3年者进行分析,观察其复发与生存情况(一般报道80％局部复发发生在手术后3年内)。资料和方法瑞典二医院自1978～1981年有 The use of a stapler in the rectal middle and lower segment of the cancer has increased the number of operations for rectal resection of the posterior end anastomosis and retention of the anus. In theory, this type of surgery can be caused by the incomplete removal of pelvic tissue and prone to recurrence. For this reason, the authors analyzed the recurrence and survival of patients who had undergone anterior resection of rectal cancer with an anastomosis for more than 3 years (generally 80% of local recurrences occurred within 3 years after surgery).
