Recurrence of Spontaneous Pneumothorax Is Not Associated with Allegedly Risk-Prone Lifestyle Conduct

Spontaneous pneumothorax (PNTX) is a common disease frequently operated at specialized thoracic surgery units. Videothoracoscopic surgery (VATS) has become the standard for treatment and recurrence prevention. While there is broad consensus regarding indications and techniques of PNTX surgery, postoperative risks and consecutive patient behavioral advice have not been sufficiently elucidated.

Single-center cohort analysis of 641 patients operated for primary PNTX by VATS over 10 years. Putatively recurrence-prone lifestyle activities (smoking status, flying habits, and scuba diving) and actual occurrence of recurrences were correlated.

Follow-up rate was 46% (279/607 patients). Mean time interval between primary operation and follow-up was 61 (range: 5-177) months. In 10 patients (3.6%), a PNTX recurrence was observed. Regarding postoperative risk behavior reported at follow-up, 28% of patients were active smokers (15 ± 7 cigarettes/day), 59% traveled by plane repeatedly, and only two patients did scuba diving (0.7%). Low body-mass-index was associated with an increase in PNTX recurrence, whereas smoking, flying, and scuba diving could not be identified as risk factors.

In our study, none of the supposed "classic" lifestyle-associated risk factors for PNTX recurrence after VATS proved to be a significant threat. Postoperative patient behavior might not be constrained by overcautious medical advice.
