经皮穴位电刺激促进腹腔镜结直肠癌术后胃肠功能恢复的Meta分析

目的 系统经皮穴位电刺激（TEAS）促进腹腔镜结直肠癌术后胃肠功能恢复的有效性。
方法 计算机检索PubMed、Cochrane library、Web of Science、Embase、中国生物医学数据库、中国知网、维普和万方数据库，检索时间为从建库至2022年7月，收集TEAS用于腹腔镜结直肠癌手术的随机对照研究（RCT），由2名研究员独立筛选文献、提取数据并对纳入研究使用Cochrane风险偏倚评估工具进行质量评价，采用RevMan 5.3软件进行Meta分析。
结果 共纳入12篇RCT，患者980例，TEAS组503例，对照组477例。与对照组比较，TEAS组术后首次肛门排气时间（SMD=-1.38，95%CI -1.87～-0.90，P<0.001）、首次排便时间（SMD=-0.81， 95%CI -1.26～-0.36，P<0.001）和首次闻及肠鸣音时间 （SMD=-1.13，95%CI -1.69～-0.57，P<0.001）均明显缩短，术后恶心呕吐发生率（RR=0.40，95%CI 0.27～0.58，P<0.001）明显降低，术后住院时间（MD=-1.72 d， 95%CI -3.22～-0.22 d，P=0.02）明显缩短。
结论 TEAS可有效促进腹腔镜结直肠癌术后胃肠功能恢复，缩短术后住院时间。

Transcutaneous electrical acupoint stimulation in promoting gastrointestinal function recovery after laparoscopic colorectal cancer surgery: a meta-analysis

Objective To system evaluate the effectiveness of transcutaneous electrical acupoint stimulation (TEAS) in promoting gastrointestinal function recovery after laparoscopic colorectal cancer surgery.
Methods PubMed, Cochrane library, Web of Science, Embase, CBM, CNKI, VIP and WanFang databases were searched systematically. The retrieval period was from the establishment of the database to July 2022. Randomized controlled trials (RCTs) of TEAS for laparoscopic colorectal cancer were collected. Two researchers screened the literature independently, extracted data and used Cochrane Risk of Bias tools to evaluate the quality of the inclusion study. RevMan 5.3 software was used for meta-analysis.
Results A total of 12 RCTs were included, with a total of 980 patients, the TEAS group included 503 patients and control group 477 patients. The Results of meta analysis showed that the first anal exsufflation time (SMD = -1.38, 95% CI -1.87 to -0.90, P < 0.001), the first defecation time (SMD = -0.81, 95% CI -1.26 to -0.36, P < 0.001), and the first bowel sound time (SMD = -1.13, 95% CI -1.69 to -0.57, P < 0.001) in the TEAS group were significantly shorter than those in the control group. The incidence of postoperative nausea and vomiting (RR = 0.40, 95% CI 0.27 to 0.58, P < 0.001) was also significantly lower than that in the control group. In addition, the postoperative hospital stay in the TEAS group was significantly shorter than that in the control group (MD = -1.72 d, 95% CI -3.22 to -0.22 d, P = 0.02).
Conclusion TEAS can effectively promote the recovery of gastrointestinal function after surgery, and shorten the duration of hospitalization.
