目的 :探讨直肠癌Dixon术后局部复发的原因。方法 :对近 10年行Dixon术 35 0例病人作回顾性分析。结果 :局部复发 39例 (8.3% ) ,复发时间为术后 3～ 18个月 ,平均 8.3个月 ,复发部位为吻合口 2 4例 ,吻合口周围 10例 ,会阴部 2例 ,系膜淋巴结 3例 ,属DukesA期 2例 ,B期 2 3例 ,C期 14例。粘液腺癌 17例 ,低分化腺癌 17例 ,印戒细胞癌 3例 ,腺癌 2例。结论 :直肠癌Dixon术后局部复发与肿瘤分期 ,细胞学类型 ,远切缘距离 ,直肠系膜是否全切 ,直肠肛管术中冲洗 ,术中无瘤操作等多因素密切相关
Objective: To investigate the causes of local recurrence after rectal cancer Dixon. Methods: A retrospective analysis of 350 patients undergoing Dixon surgery in the past 10 years was performed. Results: Local recurrence occurred in 39 cases (8.3%). The recurrence time ranged from 3 to 18 months, with an average of 8.3 months. The recurrence site was 24 anastomotic stoma, 10 cases around the anastomotic stoma, 2 cases of perineum, and mesenteric lymph node. In 3 cases, there were 2 cases of Dukes A stage, 23 cases of B stage, and 14 cases of C stage. There were 17 cases of mucinous adenocarcinoma, 17 cases of poorly differentiated adenocarcinoma, 3 cases of signet ring cell carcinoma, and 2 cases of adenocarcinoma. Conclusion: Local recurrence and tumor staging, type of cytology, distance of distal margin, complete mesorectal excision of mesorectum, flushing of rectal anal canal, and no-tumor operation are closely related to rectal cancer after Dixon operation.
