Brief Summary in Lay Language

Primary spontaneous pneumothoraces (PSP) represent a significant public health problem,
occurring in young healthy subjects without pre-existing lung disease or precedent medical
intervention or trauma with a reported incidence of up to 18-28/100 000 per year. PSP
treatment often requires thoracic surgery to restore lung expansion and to prevent de novo
lung collapse. Despite the presence of elaborated guidelines by the British Thoracic Society
(BTS) postulating apical wedge resection of the lung and total parietal pleurectomy (WRPP),
the majority of German hospitals gathered experience especially in limiting surgery to
cost-saving partial apical parietal pleurectomy or yet apical pleural abrasion (PP). Until
today, hardly any reliable data exist to analyze and compare the varying treatment
approaches regarding efficacy and efficiency. In this randomized, multi-centric clinical
trial, both treatment approaches will be compared. For this purpose, candidates for surgery
will be randomized into one of the two treatment groups after informed consent has been
obtained. Patients will be followed for 2 years by the participating centres to be able to
evaluate the long-term effect of the surgical interventions.

Brief Summary in Scientific Language

The trial will be conducted at the major thoracic surgery units in Germany. Each centre can
include patients on the basis of the presence of a PSP and the inclusion and exclusion
criteria.

After informed consent has been obtained from the study participants, each has to fill out
the standardized short-form health survey (SF-36) questionnaire and the visual analogue
scale (VAS) to determine baseline parameters for the (current) state of health and pain
level.Randomization into the two interventional groups is carried out before surgery.

Patients are operated according to good clinical practice either by pleurectomy alone (PP)
or total parietal pleurectomy with apical wedge resection of the pulmonary apex (WRPP).
Procedure related parameters (like operation time, applied suture materials including
staplers) are documented.

The postoperative care is subject to each participating centre's standards. The
postoperative course is evaluated (mortality, morbidity, duration of tube drainage,
re-interventions or operations, length of stay, need for blood substitutions).

To evaluate the long term effect of the surgical intervention, all study participants are
followed for 2 years.
