Video-Assisted Thoracoscopic Surgery Versus Tube Thoracostomy with Fibrinolytics for Treatment of Empyema in Children: A Meta-Analysis of Randomized Controlled Studies

Background: The British Thoracic Society recommended tube thoracostomy plus intra-pleural fibrinolytics to treat empyema in children in 2005. However, numerous comparative studies have suggested Video-Assisted Thoracoscopic Surgery (VATS) as a first line of treatment for pediatric empyema due to its superior outcomes, including shorter length of hospital stay (LOS). This meta-analysis aimed to compare the following: (1) the LOS for VATS versus fibrinolytics to treat empyema in children; (2) secondary post-operative outcomes (fever, O2 support, time taken for chest tube removal, analgesia, complications, failure, and abnormal chest X-ray at follow-up). Methods: The study was conducted according to PRISMA guidelines. A systematic search of PubMed, Cochrane, Web of Science, and Scopus was conducted according to PRISMA guidelines. Two independent investigators identified relevant studies, excluding case reports, opinion articles, and gray literature publications. A meta-analysis of randomized controlled trials (RCTs) was performed using RevMan 5.4, with data expressed as mean ± standard deviation (SD). Results: Of 1374 abstracts screened, 104 full-text articles were analyzed, and 6 RCTs (345 patients) were included in the meta-analysis. Patients undergoing VATS had significantly shorter LOS compared to those receiving fibrinolytics (9.1 ± 1.8 vs. 11.5 ± 2.5 days, p = 0.05). VATS patients also experienced shorter postoperative fever duration (4.2 ± 0.8 vs. 6.9 ± 4.6 days, p = 0.007) and earlier chest tube removal (5.0 ± 2.6 vs. 9.5 ± 3.3 days, p = 0.01). No significant differences were found between the two groups for other secondary outcomes. Conclusions: Children with empyema appear to benefit from VATS compared to tube thoracostomy plus fibrinolytics, with improved outcomes. Further RCTs are needed to corroborate these results.
