直肠癌患者微创保肛手术效果研究

目的：探讨直肠癌患者微创保肛手术效果。方法分别采取微创保肛手术和传统手术患者，将100例直肠癌患者随机分为微创保肛组和对照组各50例，对比两组患者的手术效果和手术并发症等情况。结果与对照组相比，微创保肛组患者术中出血量较少（63.5±9.6）ml vs（89.2±12.7）ml]、手术切口较短（4.1±0.4）cm vs（6.2±0.8）cm]、手术持续时间较短（174.5±30.1）min vs（208.4±14.8）min]、住院时间较短（7.8±0.9）天 vs（9.5±1.2天）]、切口拆线时间较早（6.6±0.5）天 vs（8.2±1.1）天]、开始排气时间较早（4.1±0.4）天vs （5.2±0.6）天]、导尿管拔除时间明显较短（4.0±0.5）天vs（5.4±0.8）天]，两组差异均具有统计学意义（均P＜0.001）。微创保肛组患者与对照组患者相比，其总的并发症发生率较低（12%vs 30%，P＝0.027），大便次数增多的并发症发生率较低（6%vs 20%，P＝0.037）。结论微创保肛术能够提高患者的手术效果，降低术后并发症发生率，值得在临床上广泛应用。

Effect of minimally invasive sphincter sparing surgery in rectal cancer patients

Objective To explore the effect of minimally invasive sphincter sparing surgery in 100 patients with rectal cancer. Method 100 patients with rectal cancer treated in our hospital from January 2010 to January 2014 were enrolled and randomized into minimally invasive sphincter sparing surgery group (n=50) and control group (n=50). Patient characteristics, effect of operation, and surgical complications of the two groups were compared. Result Compared to the control group, patients in the minimally invasive sphincter sparing surgery group had lower volumes of hemorrhage (63.5±9.6)ml vs (89.2±12.7)]ml, shorter operative incision (4.1±0.4)cm vs (6.2±0.8)cm], shorter oper-ative time (174.5 ± 30.1) min vs (208.4 ± 14.8) min], shorter hospital stay (7.8d ± 0.9)d vs (9.5 ± 1.2)d], earlier wound healing time (6.6d ± 0.5)d vs (8.2 ± 1.1)d], earlier exhaust time (4.1d ± 0.4)d vs (5.2 ± 0.6)d], earlier catheter removal time (4.0±0.5)d vs (5.4±0.8)d], the and all the differences were significant (P<0.001). Patients in the minimally inva-sive sphincter sparing surgery group had lower rates of total complications (12% vs 30%,P=0.027), less complica-tions associated with frequent bowel movement (6% vs 20%,P=0.037) than those in the control group. Conclusion Sphincter sparing surgery is favorably performed as minimally invasive surgery, which reduces the postoperative com-plications and can be widely used in clinical practice.
