Quality of life evolution after surgery for primary or secondary spontaneous pneumothorax: a prospective study comparing different surgical techniques.

The objective of the present study is to evaluate quality of life (QoL) evolution after video-assisted thoracic surgery (VATS) and anterolateral thoracotomy (AT) for primary and secondary spontaneous pneumothorax, which has not been studied prospectively until now. From January 2003 to December 2004, QoL was prospectively recorded in 20 consecutive patients, using the European Organisation for Research and Treatment of Cancer (EORTC) QoL Questionnaire-C30 and the lung specific module LC-13. Questionnaires were administered before surgery and 1, 3, 6 and 12 months postoperatively (MPO) with response rates of 100%, 85%, 80%, 65% and 60%, respectively. In this prospective, non-randomized study, all patients had wedge resection and apical pleurectomy, 45% by video-assisted thoracic surgery (VATS), and 55% by anterolateral thoracotomy (AT). In general, patients QoL subscales improved after surgery. After VATS, pain (3 MPO P=0.012), dyspnoea (1 MPO P=0.030) and thoracic pain (1 MPO P=0.038) decreased significantly. After AT, a significant increase was seen in general QoL (1 MPO P=0.036, 3 MPO P=0.034, 12 MPO P=0.025), physical (6 MPO P=0.025) and emotional functioning (12 MPO P=0.017). Dyspnoea (12 MPO P=0.042) and coughing (6 MPO P=0.046) decreased after AT. After surgery, AT and VATS are comparable in QoL evolution with the exception of a significant difference at 1 MPO in physical, role and cognitive functioning (P=0.002, P=0.002 and P=0.0018, respectively) and dyspnoea (P=0.041) in favour of VATS. Comparing VATS and AT in QoL evolution, significant differences are seen in thoracic pain evolution in favour of VATS (6 MPO P=0.037). After surgery, AT and VATS are comparable in QoL subscales with exception of a significant difference at 1 MPO in favour of VATS. Dyspnoea and coughing improved after surgery.
