Objective:To compare the clinical effects between laparoscopy and laparotomy preserving anus sphincter surgery in low rectal cancer. Methods:Sixty-two patients with low rectal cancer were divided into the control group(27 cases) and observation group (35 cases). The control group and observation group were treated with laparotomy and laparoscopy preserving anus sphincter surgery, respectively. The perioperative situation, incidence of postoperative complications and specimen oncology and anus function after six months of operation between two groups were compared. Results:The operative time,blood loss,exhaust time and hospitalization time in observation group were significantly lower than those in control group(P 0. 05). The differences of the average of diameter and length of tumor,distance from the distal edge of the tumor to the distal margin and number of lymph nodes dissected between two groups were not statistically significant(P>0. 05). The differences of the incidence rate of totally anal incontinence and 6-month Kirwan standard anus control ability grading between two groups were not statistically significant(P>0. 05). Conclusions:Laparoscopy preserving anus sphincter surgery in the treatment the low rectal cancer is small surgical trauma and quick postoperative recovery, the clinical effect of which can achieve the same radical cure of laparotomy preserving anus sphincter surgery.%目的:探讨腹腔镜保肛手术与开腹保肛手术在低位直肠癌中的临床疗效.方法:选取手术治疗的低位直肠癌患者62例,按照手术方法分为开腹保肛手术组(对照组)27组和腹腔镜保肛手术组(观察组)35例.比较2组患者围手术期情况和术后并发症发生情况、标本肿瘤学情况及术后半年的肛门功能.结果:观察组手术时间、出血量、肛门排气时间和住院时间均显著低于对照组(P0.05);2组肿块平均直径、长度和肿块下缘距远切缘距离、清扫淋巴结数目等肿瘤学情况差异均无统计学意义(P>0.05);2组患者均未出现肛门完全失禁,且术后6个月KIRWAN标准肛门控便能力分级差异无统计学意义(P>0.05).结论:腹腔镜保肛低位直肠癌手术具有手术创伤小、术后恢复快的优点,且能达到与开腹保肛低位直肠癌手术相同的根治效果.
