目的总结经肛门显微外科手术治疗直肠肿瘤疗效的影响因素。方法回顾性分析60例经肛门显微外科手术治疗直肠肿瘤患者,对其中术后复发者进行影响因素进总结,并进行logistic多因素分析。结果本研究有无效9例,发生率为15%,疗效单影响因素有肿瘤浸润深度(T2分期)、病灶距离肛缘距离(≥10 cm)、切除深度、存在并发症(P<0.05),而与性别、年龄、肿瘤大小、CEA含量、CA199含量无关(P>0.05);logistic多危险因素分析,浸润深度、病灶距离肛缘距离、切除深度、并发症是经肛门显微外科手术治疗直肠肿瘤疗效独立影响因素(P<0.05)。结论经肛门显微外科手术治疗直肠肿瘤疗效影响因素有浸润深度、病灶距离肛缘距离、切除深度、并发症,而与其他因素无关。
Objective To summarize the influencing factors of rectal cancer treated by anal microsurgery. Methods Retrospective analysis of 60 cases of rectal tumors treated by microsurgical anus microsurgery, summarizes the influencing factors of postoperative recurrence and carries out logistic multivariate analysis. Results There were 9 cases were ineffective in this study, the incidence rate was 15%. The single effect factors included the depth of tumor infiltration (T2 stage), the distance from the anal verge (≥10 cm), the depth of resection and the complications (P <0.05) But no correlation with sex, age, tumor size, CEA content and CA199 content (P> 0.05). Logistic multi-risk factors analysis, infiltration depth, lesion distance from anal verge, depth of resection and complication were transrectal microsurgical treatment of rectum Tumor independent factors (P <0.05). Conclusion Rectal microsurgery for the treatment of rectal tumor with depth of invasion, the distance from the anal verge, depth of resection, complications, but not with other factors.
