Pleurectomy Versus Pleural Abrasion in Patients With Spontaneous Pneumothorax

Overview

Pneumothorax refers to air in the pleural cavity (i.e. interspersed between the lung and the chest wall).1 Primary spontaneous pneumothorax (PSP) mostly occurs in healthy individuals without an apparent cause, probably due to the rupture of subpleural blebs located mostly on the apex of the lung or the apical segment of the lower lobe. Compared to PSP, a secondary spontaneous pneumothorax (SSP) occurs in the setting of underlying pulmonary disease, like COPD.2 Surgical treatment involves resection of apical bleb disease and pleurodesis which could be chemical or mechanical. Mechanical pleurodesis accomplished either via pleurectomy or pleural abrasion.3 In this study, we aim to compare the efficiency and recurrence risk of pleural abrasion versus pleurectomy in patients with Spontaneous pneumothorax.

Pneumothorax is a relatively common clinical problem which can occur in individuals of any age. Irrespective of aetiology (primary, or secondary to lung disorders or injury), immediate management depends on the extent of cardiorespiratory impairment, degree of symptoms and size of pneumothorax. 4 The presentation of a pneumothorax varies between minimal pleuritic chest discomfort and breathlessness to a life threatening medical emergency with cardiorespiratory collapse requiring immediate intervention.5-7 Typical signs include reduced breath sounds, reduced ipsilateral chest expansion and hyper resonant percussion note. Mediastinal shift away from the affected side, tachycardia, tachypnea and hypotension occur in Tension pneumothorax. 8 Pneumothorax can be categorized as spontaneous which maybe primary or secondary and traumatic according to aetiology. Occasionally, individuals may develop a concomitant haemothorax due to bleeding caused by shearing of adjacent subpleural vessels when the lung collapses.4 A primary spontaneous pneumothorax (PSP) is a condition that occurs predominantly in young and thin male individuals who do not have any history of underlying lung disease. Although it is mostly attributed to the rupture of a subpleural bleb or bulla, the exact cause of PSP is still unknown.1 Moreover, current cigarette smoking greatly increases the risk of developing PSP by as much as nine times, with evidence of a dose-response relationship.9 Secondary spontaneous pneumothorax (SSP) frequently occurs in association with primary diseases, such as chronic obstructive pulmonary disease (COPD), interstitial pneumonia (IP), and pulmonary fibrosis disease (PFD). 10 Treatment of spontaneous pneumothorax depends on the patient's condition and can range from conservative treatment, drainage, and pleurodesis, to surgical treatment.10 Surgical treatment is based on resection of bullous lesions causing air leakage and techniques to prevent recurrence. Surgical treatment without additional pleurodesis may increase the risk of recurrence, Various pleurodesis techniques such as chemical pleurodesis or mechanical pleurodesis via pleural abrasion or pleurectomy are used to reduce the recurrence rate.1
