INTRODUCTION: Primary spontaneous pneumothorax (PSP) and its high recurrence rate pose a therapeutic challenge to both patients and their managing surgeons. Mechanical or chemical pleurodesis can be used to prevent recurrence, but the optimal treatment often remains a matter of debate. This meta-analysis aims to compare the outcomes between mechanical and chemical pleurodesis following bullectomy for PSP.
MATERIALS AND METHODS: Studies published up to 2019 were searched from Medline, Embase, Google Scholar, and Cochrane databases. A meta-analysis of randomized controlled trials (RCTs) and observational cohort studies (OCSs) comparing outcomes between mechanical and chemical pleurodesis for PSP was performed.
RESULTS: Seven studies (one RCT and six OCSs) were included, comprising 1,032 cases of mechanical (799 abrasions, 202 pleurectomies, and 31 unspecified abrasions/pleurectomies/both), and 901 cases of chemical (643 talc, 69 minocycline, and 189 unspecified talc/kaolin) pleurodesis. The recurrence rate of pneumothorax after chemical pleurodesis (1.2%) was significantly lower than mechanical pleurodesis (4.0%) (pooled odds ratio [OR] = 3.00; 95% confidence interval [CI] = 1.59-5.67; p = 0.0007; I 2 = 19%). Hospital stay was also slightly shorter in the chemical pleurodesis group (pooled mean difference [MD] = 0.42 days; 95% CI = 0.12-0.72; p = 0.005; I 2 = 0%). There was no statistically significant difference in postoperative complications (pooled OR = 1.18; 95%CI = 0.40-3.48; p = 0.76; I 2 = 71%) and operative time (pooled MD = 3.50; 95%CI = -7.28 to 14.28; p = 0.52; I 2 = 99%) between these two groups.
CONCLUSION: Chemical pleurodesis is superior to mechanical pleurodesis following bullectomy for PSP in reducing hospital stay and recurrence rate. However, more RCTs with longer follow-up are necessary to demonstrate the benefit of chemical pleurodesis for PSP.
