Abstract
OBJECTIVE: Primary spontaneous pneumothorax is a common disease that develops in relatively young healthy patients. Although smoking is generally believed to have a negative effect on the lungs, some authors reported that smokers with primary spontaneous pneumothorax had significantly lower postoperative recurrence rates than nonsmokers. This unexpected result suggests that primary spontaneous pneumothorax is classified into two categories: smoking-related young pneumothorax and residual primary spontaneous pneumothorax. We compared these two categories to determine their characteristics and corresponding surgical results. METHODS: Between January 2009 and December 2018, we enrolled 267 consecutive cases that underwent first surgery for primary spontaneous pneumothorax in our hospital. A total of 252 eligible cases (211 residual primary spontaneous pneumothorax and 41 smoking-related young pneumothorax) underwent evaluation. Smoking-related young pneumothorax cases were defined as cases with characteristic HRCT findings and smoking habit. RESULTS: The mean ages for the residual primary spontaneous pneumothorax and smoking-related young pneumothorax groups were 25.9 ± 13.1 and 30.5 ± 6.9 years, respectively. The groups included 186 (88.2%) and 41 (100.0%) men, and the mean body mass indices were 19.1 ± 2.2 and 20.0 ± 1.9, respectively. Fifty-nine (28.0%) and 41 (100.0%) subjects were smokers, and there were 43 (20.4%) and 1 (2.4%) cases of postoperative recurrence, respectively. These results were significantly different between the two groups. CONCLUSIONS: Individuals with smoking-related young pneumothorax were older, predominantly men, and had higher body mass index and significantly lower postoperative recurrence rates than those with residual primary spontaneous pneumothorax.
