全直肠系膜切除术治疗低位直肠癌疗效观察

目的探讨全直肠系膜切除术（TME）对低位直肠癌的治疗价值.方法119例直肠癌患者,肿瘤距肛缘均在8 cm以内.54例应用传统手术方法治疗（传统组）,65例应用TME治疗（TME组）.对两组患者的平均手术时间、术中失血量、住院天数和局部复发率进行比较.结果TME组平均手术时间为118 min,术中失血量100mL,而传统组则为182min,340mL,差异有统计学意义（均P＜0.05）;两组局部复发率分别为9.23%和35.18%（P＜0.01）.住院天数无明显差异.结论应用TME治疗低位直肠癌,手术时间短,出血少,局部复发率低,是治疗低位直肠癌的首选术式.

The effect of total mesorectal excision for low rectal cancer

Objective To investigate the therapeutic effect of total mesorectal excision(TME) for low rectal cancer.Methods One hundred nineteen patients with rectal cancer,located on an average within 8 cm of the anal verge,were included in the study.Fifty-four patients underwent traditional operation,and sixty-five patients underwent total mesorectal excision.Operation time,loss of blood at operation and local recurrence rates were compared between the two groups.Results The average operation time and blood loss were 118 minutes,and 100mL respectively in TME group,and they were 182 minutes,and 340 ml respectively in traditional operation group.There were significant differences between them(all P<0.05).The local(recurrence) rates were 9.23% and 35.18% respectively in the two groups(P<0.01),there was not(significant) difference on the hospital stay between the two groups(P>0.05).Conclusions In TME group,operation time was shorter,operative blood loss was less,and local recurrence rate was lower.TME should be applicated for patients with low rectal cancer.
