Population-based study on surgical care for primary spontaneous pneumothorax.

The optimal surgical strategy for primary spontaneous pneumothorax remains a matter of debate and variation in surgical practice is expected. This variation may influence clinical outcomes, such as postoperative complications and length of stay. This national population-based registry study provides an overview and extent of variability of current surgical practice and outcomes in the Netherlands. To identify national patterns of care and between-hospital variability in the treatment of primary spontaneous pneumothorax, patients who underwent surgical pleurodesis and/or bullectomy between 2014- 2021, were identified from the Dutch Lung Cancer Audit-Surgery database. The type of surgical intervention, postoperative complications, length of stay and ipsilateral recurrences were recorded. Out of 4,338 patients, 1,851 patients were identified to have primary spontaneous pneumothorax. The median age was 25 years (interquartile range 20-31) and 82% was male. The most performed surgical procedure was bullectomy with pleurodesis (83%). The overall complication rate was 12% (Clavien Dindo grade ≥III 6%), with the highest recorded incidence for persistent air leak >5 days (5%). Median postoperative length of stay was 4 days (interquartile range 3-6) and 0.7% underwent a repeat pleurodesis for ipsilateral recurrence. Complication rate and length of stay differed considerably between hospitals. There were no differences between the surgical procedures. In the Netherlands, surgical patients with primary spontaneous pneumothorax are preferably treated with bullectomy plus pleurodesis. Postoperative complications and length of stay vary widely and are considerable in this young patient group. This may be reduced by optimization of surgical care.
