Background: Primary spontaneous pneumothorax (PSP) occurs with no apparent lung disease, while secondary spontaneous pneumothorax occurs mostly as a complication of underlying lung diseases. The current study was aimed to study the presenting features of PSP patients, including demographics [gender, age, smoking, height and weight, and body mass index (BMI)], symptoms, and seasonality among adult patients in King Khalid University Hospital (KKUH) during the period from 2010 to 2016.
Methodology: A quantitative, observational, retrospective, case-series study was conducted among 132 patients who were diagnosed with PSP disease from January 2010 to December 2016 at KKUH, Riyadh, Saudi Arabia was studied. Data were collected by reviewing the transfer sheet case report form, and by reviewing variables in the medical records of PSP patients.
Results: The mean age was 24.62 with standard deviation (SD) ± 8.8-year old. Among the total, 88.6% of patients were males (11.4% females). Furthermore, 59.8% were smokers and 40.2% were a non-smoker. BMI average was 19.4 kg/m2. The season of the attack was more in spring and summer accounting a 29.6% for each. Also, 90.9% of the patients were treated surgically. The average duration of hospital stay after surgical management was 6.45 days (SD ± 3.15), recurrence after surgical management was (4.1%).
Conclusion: Based on the present case series study, the majority of PSP patients were male, of the young age group, with a low BMI. Most of the admissions occurred during the warm climate (spring/summer). Furthermore, short hospital stays and low state of recurrence were noted among the patients who were treated surgically.
