Chronic obstructive pulmonary disease (COPD) is a very heterogeneous disease characterised by an obstructive lung pattern that constitutes worldwide a major cause of high morbidity and mortality. In the last decades, lung volume reduction surgery (LVRS) has demonstrated to be a potential good alternative to transplantation in patients affected by COPD. The trend toward minimally invasive techniques resulted not only in surgical procedures better tolerated by the patients but also in several endoscopic treatments modality that are rapidly gaining ground.

Background: Postpneumonectomy syndrome (PPS) is a rare complication after pneumonectomy. It consists of an excessive mediastinal shift resulting in compression and stretching of the tracheobronchial tree and the esophagus. The aim of this study was to give a comprehensive overview of diagnosis, variety of symptoms and evaluation of surgical treatment of PPS. Methods: We retrospectively reviewed the charts of all our patients with PPS since 1994 with respect to symptomatology, treatment and outcome. Our results were compared with case reports and case seriesintheliterature.Results:Sixwomenwithamedianageof56.5years(range49—65)developedPPSafterpneumonectomyforthetreatment of lung cancer. Four presented with a right PPS and two with a left PPS, respectively. Symptomsconsisted of shortness of breath in all patients and dysphagia as well as heartburn in two patients. Correction of PPS required re-exploration of the pneumonectomy space, reposition of the mediastinum followed by the insertion of single silicone prosthesis in five patients or fixation of the mediastinum with a xenopericardial graft in one patient. We could observe an improvement of the FEV1/FVC ratio in all our patients and the clinical improvement of shortness of breath was better than we expectedby changes of lung function.Four patients returnedto theirregular activities with a follow-up of four years. We found 73 cases of PPS in the literature, on the right side in 50 patients (68%) and on the left side in 23 patients (32%). Fifty-nine patients (81%) were treated surgically. Symptoms can be suspicious for cardiogenic origin and vary from heartburn to recurrent syncopes. Conclusion: PPS is rare and not predictable.Itcanoccurafterrightorleftpneumonectomy.
