双器械吻合联合全直肠系膜切除Dixon保肛手术治疗直肠癌的临床效果观察

目的  探讨双器械吻合联合全直肠系膜切除Dixon保肛手术治疗直肠癌的临床治疗效果。方法  选取2013年4月-2015年4月张家港市第一人民医院诊治的80例直肠癌患者资料进行分析，采用随机数字方法将患者分为对照组和实验组，两组均应用全直肠系膜切除Dixon保肛手术治疗，对照组联合单器械吻合予以治疗，实验组联合双器械吻合进行治疗，比较两组患者的临床疗效。结果  实验组患者手术过程中出血量少，住院时间短，肠道功能恢复较早，患者尿管留置时间短，与对照组患者比较差异有统计学意义（P <0.05）；患者治疗后实验组并发症发生率显著低于对照组（P <0.05）；实验组患者肛门功能良好率为87.5%，显著高于对照组（67.5%）（P <0.05）。结论  应用双器械吻合联合全直肠系膜切除Dixon保肛手术治疗直肠癌疗效显著，患者肛门功能恢复程度好，值得临床上推广应用。

Clinical effect of Dixon anus preserving operation with double stapling and total mesorectal excision for rectal cancer

Objective To investigate the clinical therapeutic effect of Dixon sphincter preserving surgery with double stapling anastomosis combined with total mesorectal resection for rectal cancer. Methods The clinical data of 80 patients with rectal cancer treated in our hospital from April 2013 to April 2015 were analyzed. Using random digital methods, they were divided into experimental group and control group. Both groups received Dixon anus preserving operation with total mesorectal excision for treatment; the control group had a combination with single-instrument anastomosis, while the experimental group had double-stapling anastomosis. Clinical curative effect was compared between both groups. Results The patients in the experimental group had less blood loss, shorter hospital stay and earlier recovery of intestinal function compared to the patients in the control group, the differences were significant (P < 0.05). The complication rate in the experimental group was significantly lower than that in the control group (P < 0.05). The good rate of anal function in the experimental group was 87.5%, which was significantly higher than 67.5% in the control group (P < 0.05). Conclusions When double stapling anastomosis combined with total mesorectal resection is applied to Dixon retention anus operation for rectal cancer, the curative effect is distinct, the recovery of patients'' anal function is good. Therefore it is worth popularization and application.
