Abstract:
Objective: To systematically compare the effectiveness and safety of single-hole and double-hole thoracoscopy for the treatment of primary palmar hyperhidrosis.
Methods: The randomized controlled or non-randomized controlled clinical trials of single-hole and double-hole thoracoscopic surgery for primary palmar hyperhidrosis included from January 1, 2010 to September 19, 2022 were searched in Wanfang database, China National Knowledge Infrastructure (CNKI), Weipu (VIP), SinoMed, PubMed, Web of Science and Embase.The singlehole thoracoscopic group (single-hole group) was treated with conventional thoracoscopic surgery through traditional axillary single incision, and the double-hole thoracoscopic group (double-hole group) was treated with conventional thoracoscopic surgery through axillary double incision.Two researchers independently searched, screened literature, extracted data, and evaluated the quality of randomized controlled trial (RCT) literature included using the Cochrane bias risk assessment tool.The quality of non-RCT literature included was evaluated using the Newcastle-Ottawa scale (NOS).Meta-analysis was conducted by using RevMan5.4.1 software.
Results: A total of 935 literatures were retrieved.After layer-by-layer screening, 13 literatures were finally included, involving 1, 124 patients, including 556 patients in the single-hole group and 568 patients in the double-hole group.The results of meta-analysis showed that the incision length of the single-hole group was shorter than that of the double-hole groupstandardized mean difference (SMD)=-4.15, 95% confidence interval (
CI) (-5.41, -2.89),
P< 0.001.The operation time of single-hole group was shorter than that of double-hole groupmean difference (MD)=-5.87,95%
CI (-7.52,-4.21),
P< 0.001.The postoperative hospitalization time of patients in the single-hole group was shorter than that in the double-hole groupMD=-0.76, 95%
CI (-1.83, -0.34),
P=0.000 4.The postoperative pain in the single-hole group was less severe than that in the double-hole group.MD=-1.31, 95%
CI (-1.70, -0.93),
P< 0.001.There was no significant difference in the incidence of postoperative compensatory hyperhidrosis between the two groupsRisk Ratio (
RR)=0.82, 95%
CI (0.53, 1.27),
P=0.37.The incidence of postoperative recurrent palmar hyperhidrosis in the patients undergoing double-hole thoracoscopy was higher than that in the patients undergoing single-hole thoracoscopy
RR=0.26, 95%
CI (0.07, 0.93),
P=0.04.The incidence of postoperative complications in the patients undergoing double-hole thoracoscopy was higher than that in the patients undergoing single-hole thoracoscopy
RR=0.34, 95%
CI (0.19, 0.64),
P=0.000 7.
Conclusion: The safety and effectiveness of singlehole thoracoscopy for the treatment of primary palmar hyperhidrosis are superior to those of double-hole thoracoscopy.
