Background:
To systematically evaluate the efficacy of thoracoscopic surgery compared to traditional thoracotomy for thymic tumors.
Methods:
We performed a literature search on computer of the PubMed, Embase, Cochrane Library, Web of Science, China Biology Medicine (CBM), WanFang, and China national knowledge infrastructure (CNKI) databases from the date of establishment of the database to April 2021, and retrieved randomized controlled trials (RCTs) and cohort studies on thoracoscopic surgery and thoracotomy with conventional open thoracic surgery. After independent screening of the literature by two assessors, the relevant data was extracted and the risk of bias in the included studies was evaluated. RevMan 5.3 software was used to perform the analysis.
Results:
Five RCTs and eight cohort studies were ultimately included, with a total of 1,093 patients. The results of meta-analysis showed that compared with traditional thoracoscopic surgery, thoracoscopy had shorter surgery duration (OR =22.2, 95% CI: -31.92, -12.52, P<0.00001), ICU stay (OR =0.29, 95% CI: 0.20, 0.42, P<0.00001), and hospitalization time (OR =0.531, 95% CI: 0.41, 0.69, P<0.00001) times, as well as reduced chest tube drainage time (OR =0.49, 95% CI: 0.33, 0.73, P=0.0004), less intraoperative bleeding (OR =43.27, 95% CI: -50.94, -35.60, P<0.00001), and a lower incidence of postoperative complications (OR =0.19, 95% CI: 0.11, 0.34, P<0.00001). However, the tumor recurrence rate was not significantly different between the two procedures (OR =0.69, 95% CI: 0.32, 1.48, P=0.34).
Discussion:
The existing evidence suggests that thoracoscopic surgery has shorter surgery duration, ICU stay time, hospitalization time, reduced thoracic tube drainage, less intraoperative bleeding, and a lower incidence of postoperative complications compared with traditional thoracotomy surgery. However, due to the poor quality of the included research, more high-quality studies need to be conducted to verify the above conclusions.
