Abstract

Surgery is the recommended and most effective means of preventing the recurrence of primary spontaneous pneumothorax (PSP). However, the conventional belief amongst most clinicians is that surgery should not be routinely offered to patients with an uncomplicated first episode of PSP. The view that surgery should be reserved for recurrent episodes of ipsilateral PSP is based on an apprehension regarding traumatic thoracic surgery combined with a perception that recurrences after a single episode of PSP are unlikely. Modern advances in minimally invasive thoracic surgery have now dramatically reduced the morbidity of PSP surgery. Such surgery is now safe, effective and causes minimal indisposition for patients. On the other hand, modern clinical data suggests that recurrence rate of PSP is perhaps much higher than previously assumed, with more than half of patients experiencing a second episode within several years of the first. With such new appreciations of the current situation, it is appropriate to now consider offering surgery to patients even after the first episode of PSP.

Core tip: Traditional guidelines advise that surgery is unnecessary for patients suffering a first episode of primary pneumothorax. However, such thinking was based on an incomplete picture of the frequency of recurrence and on older, relatively traumatic surgical approaches. Today, advanced surgical techniques allow effective bullectomy and pleurodesis to be safely delivered with only minimal morbidity or inconvenience to patients. Evidence is also emerging that recurrence may be more common than previously believed. It is perhaps time to allow clinical practices to catch up with modern medicine, and to consider surgery even after a first episode of primary pneumothorax.
