Purpose : Primary spontaneous pneumothorax (PSP) occurs mainly in thin, tall and young adult males and peak age incidence is known as 20 to 30 years. In this study, we investigated the age-related incidence changes in PSP during the last 20 years.
Methods : We retrospectively analyzed the medical records of patients aged 10 to 35 years who visited our institute between January 1996 and December 2015 for PSP. Patients who had recurrence, previous lung surgery history or other lung disease were excluded.
Results : The total number of patients was 2,550 of which 2306 patients (90.4%) were male. The mean age at first occurrence of PSP was 21.0±6.0 years old. In 1998, the mean age at first occurrence was 22.5 years old, and decreased linearly, eventually reaching 20.2 years old in 2015 (Figure 1). This decrease was statistically significant (p<0.0001). In the review of age distribution, the percentage of patients under 18 years old was below 40% by 2006, but it increased to over 50% from 2007, and the proportion is gradually increasing. The mean height and BMI of all patients were not changed during 20 years, but, the height of the patients between 18 and 20 years of age increased significantly.
Conclusion : During the last 20 years, the age at first occurrence of PSP is gradually decreasing, which is thought to be related to the height growth of younger patients. Considering the high recurrence rate of surgery for PSP at younger age, strategies for treatment of PSP should be also reconsidered.
