探究不同体位下行腹腔镜结直肠癌手术的临床效果，及其对患者的手术舒适度的影响。

将2015年6月至2017年6月期间确诊并进行手术的结直肠癌患者86例纳入研究，根据手术时体位的不同分为A组(46例)和B组(40例)，其中A组患者在改良截石位下进行腹腔镜手术，B组患者在人形平卧位下完成腹腔镜手术。数据由SPSS20.0软件完成分析。手术时间以均值±标准差形式表示，组间比较采用独立t检验；并发症发生率以率的形式表示，组间比较采用χ²检验；P<0.05差异有统计学意义。

A组的平均手术时间为(2.2±0.9) h明显少于B组的平均手术时间(3.8±0.7) h，组间比较差异有统计学意义，t＝6.143, P<0.05。本研究患者术后并发症主要包括下肢疼痛、麻木、肿胀，腹痛等，A组并发症发生率为4.3%；B组并发症发生率为35.0%，差异有统计学意义，P<0.05。

对结直肠癌患者进行腹腔镜手术时选择改良截石位体位，能缩短手术时间和减少手术并发症的发生，值得临床推广应用。

To explore the clinical effect of laparoscopic colorectal cancer surgery in different posture and its effect on the operation comfort of patients.

86 patients with colorectal cancer who were diagnosed and operated in our hospital from June 2015 to June 2017 were included in the study, according to the different posture in the operation were divided into Group A (46 cases) and Group B (40 cases), in which Group A were treated with laparoscopic surgery under the modified cutting stones and Group B subjects performed laparoscopic surgery under the human supine position. The clinical effects of the two groups were evaluated with the operation time and postoperative complication as the main indexes. Data is analyzed by SPSS 20.0 software. The operation time was expressed in the form of (mean±standard deviation), independent t test was used among the groups, and the incidence rate of complication was expressed in the form of χ² test. The difference of P<0.05 was statistically significant.

The average operation time of Group A (2.2±0.9) h, was significantly less than the average operation time(3.8±0.7) h of B Group , and the difference was statistically significant, t=6.143, P<0.05. The postoperative complications of this study included lower limb pain, numbness, swelling, abdominal pain and the incidence of complication in Group A was 4.3%., the incidence of complication in Group B was 35.0%, the difference was statistically significant, P<0.05.

By choosing the improved cutting stone position in the laparoscopic surgery in patients with colorectal cancer can shorten the operation time and reduce the complication of operation, which is worthy of clinical application.
