摘要: 目的

系统评价经肛门内镜微创手术(transanal endoscopic microsurgery,TEM)和根治性切除术(radical surgery,RS)治疗T1和T2期直肠癌的疗效。

方法

通过检索Pubmed、Cochrane Library、Embase、Web of science、知网,万方等数据库,收集2021年8月之前发表的关于TEM和RS治疗直肠癌的随机对照试验和病例对照研究的临床资料,使用RveMan4.2软件对筛选之后的文献数据进行Meta分析。

结果

纳入14篇文献包括3 680名患者,结果显示,在手术的安全性方面,TEM的手术时间[WMD = -96.94,95%CI(-115.79 ~ -78.1),P< 0.001]、术中失血量[WMD = -304.64,95%CI(-446.85 ~ -162.42),P< 0.001]、术后并发症[RR= 0.22,95%CI(0.16 ~ 0.30),P< 0.001]与RS组相比差异有统计学意义;在肿瘤学方面,TEM切缘阳性率[RR= 7.39,95%CI(3.75 ~ 14.57),P< 0.001]、局部复发率[RR = 2.54,95%CI(1.60 ~ 4.02),P< 0.001]、总体复发率[RR= 1.62,95%CI(1.11 ~ 2.35),P= 0.01]与RS组相比差异有统计学意义;TEM组生存率[RR= 1.00,95%CI(0.95 ~ 1.05),P= 0.92]、围手术期病死率[RR= 0.25,95%CI(0.06 ~ 0.99),P= 0.05]与RS组相比差异无统计学意义。

结论

对于早期直肠癌,TEM手术时间、术中出血量、术后并发症低于RS,但在切缘阳性率、局部复发率,总体复发率高于RS,在生存率方面TEM与RS接近,但本研究纳入的文献大部分为非随机对照试验,肿瘤的分期方面存在差异,部分研究术前进行新辅助治疗,以上结论仍需要大样本的高质量的随机对照试验来验证。

Abstract: Objective

To systematically evaluate the efficacy of transanal endoscopic microsurgery (transanal endoscopic microsurgery, TEM) and radical resection (radical surgery, RS) in the treatment of T1 and T2 rectal cancer by searching the databases of Pubmed, Cochrane Library, Embase, Web of science, Zhiwang, Wanfang, etc.

Methods

The clinical data of randomized control trials and case-control studies on rectal cancer treated with TEM and RS published before August 2021 were collected, and the selected literature data were analyzed by Meta using RveMan 4.2 software.

Results

Fourteen articles were included, including 3 680 patients, the results showed that, in terms of the safety of the operation, there were significant differences between TEM group and RS group in hand operation [WMD = -96.94, 95%CI(-115.79 ~ -78.1),P< 0.001], intraoperative blood loss [WMD = -304.64, 95%CI(-446.85 ~ -162.42),P< 0.001] and postoperative complication [RR= 0.22,95%CI(0.16 ~ 0.30),P< 0.001]. In oncology, the positive rate of TEM margin (RR= 7.39). 95%CI(3.75 ~ 14.57),P< 0.001, local recurrence rate [RR= 2.54,95%CI(1.60 ~ 4.02),P< 0.001], and overall recurrence rate [RR= 1.62,95%CI(1.11 ~ 2.35),P= 0.01] were significantly different from those in RS group. The survival rate and perioperative mortality in TEM group were not significantly different from those in RS group.

Conclusion

For early rectal cancer, the operation time, intraoperative blood loss and postoperative complications of TEM are lower than those of RS, but the positive rate of incisal margin, local recurrence rate and overall recurrence rate of TEM are higher than those of RS, and the survival rate of TEM is similar to that of RS. However, most of the literature included in this study are non-randomized controlled trials, and there are differences in tumor stages, some of which are treated with neoadjuvant therapy before operation. The above conclusion still needs a large sample of high-quality randomized controlled trials to verify.
