RESUMO
The use of extracorporeal membrane oxygenator instead of standard cardiopulmonary bypass during lung transplantation is debatable. Moreover, recently, the concept of prolonged postoperative extracorporeal membrane oxygenator (ECMO) support has been introduced in many transplant centers to prevent primary graft dysfunction (PGD) and improve early and long-term results. The objective of this study was to review the results of our extracorporeal life support strategy during and after bilateral sequential lung transplantation (BSLT) for pulmonary artery hypertension. We review retrospectively our experience in BSLT for pulmonary artery hypertension between January 2010 and August 2018. A total of 38 patients were identified. Nine patients were transplanted using cardiopulmonary bypass (CPB), in eight cases CPB was followed by a prolonged ECMO (pECMO) support, 14 patients were transplanted on central ECMO support, and seven patients were transplanted with central ECMO support followed by a pECMO assistance. The effects of different support strategies were evaluated, in particular in-hospital morbidity, mortality, incidence of PGD, and long-term follow-up. The use of CPB was associated with poor postoperative results and worse long-term survival compared with ECMO-supported patients. Predictive preoperative factors for the need of intraoperative CPB instead of ECMO were identified. The pECMO strategy had a favorable effect to mitigate postoperative morbidity and mortality, not only in intraoperative ECMO-supported patients, but even in CPB-supported cases. In our experience, ECMO may be considered as the first choice circulatory support for lung transplantation. Sometimes, in very complex cases, CBP is still necessary. The pECMO strategy is very effective to reduce incidence of PGD even in CPB-supported patients.

Malignant pleural mesothelioma (MPM) is an aggressive asbestos-related tumour with poor prognosis. To date, a multimodality treatment, including chemotherapy and surgery, with or without radiotherapy, is the gold standard therapy for selected patients with epithelioid and early-stage MPM. In this setting, the goal of surgery is to achieve the macroscopic complete resection, obtained by either extrapleural pneumonectomy or pleurectomy/decortication. Failure, in local and/or distant sites, is one of the major concerns; in fact, there has been no established treatment for the recurrence of MPM after the multimodal approach, and the role of surgery in this context is still controversial. By using electronic databases, studies that included recurrent MPM patients who underwent a second surgery were identified. The endpoints included were: a pattern of recurrence, post-recurrence survival (PRS), and the type of second surgery. When available, factors predicting better PRS and perioperative mortality and morbidity were collected. This systematic review offers an overview of the results that are currently obtained in patients undergoing a second surgery for relapsed MPM, with the aim to provide a comprehensive view on this subject that explores if a second surgery leads to an improvement in survival.
RESUMO
BACKGROUND: Bronchoplastic procedures have become the reference standard in the lung parenchyma-sparing treatment of centrally located bronchopulmonary tumors. Two schools of thought exist regarding performing a bronchial sleeve resection: those who wrap the anastomosis with a pedicled flap and those who leave the anastomosis unprotected. We performed a study comparing these 2 methods. METHODS: This study was a retrospective multicenter observational analysis of 90 consecutive patients undergoing bronchial sleeve resections for neoplastic disease between June 2009 and July 2019. Group A (60 patients) underwent bronchial wrapping and group B (30 patients) did not undergo wrapping. RESULTS: The only difference between group A, which had 5 patients (8.3%), and group B, which had 10 patients (33.3%), regarding general characteristics was the presence of diabetes (P = .003). There were no differences in surgical, postoperative, and follow-up characteristics. There was no statistically significant difference between groups (group A, 9 patients [15%]; and group B, 6 patients [20%]) in terms of anastomotic complications at 1 year (P = .425). Diabetes was an independent predictive factor for anastomotic complications at 1 year (P = .035). The number of postoperative complications (P < .001) was an independent risk factor for length of hospital stay. CONCLUSIONS: We found no differences between groups in terms of postoperative complications and length of hospital stay, which confirmed previous reports that sleeve resections may be performed safely without bronchial wrapping.

BACKGROUND: Catamenial pneumothorax (CP) is defined as a recurrent, spontaneous pneumothorax occurring within a day before or 72 h after the onset of menstruation. Most first episodes go undiagnosed and treated as primary spontaneous pneumothorax, and only after recurrence is the clinical suspicion of CP raised. No gold-standard management approach exists, especially in terms of managing diaphragmatic involvement. METHODS: This study is a single-centre cohort retrospective study of 24 female patients who underwent surgery for pneumothorax due to diaphragmatic endometriosis between January 2008 and December 2016. Two groups were compared: a group that underwent pleurodesis alone (8 patients) and a group that underwent diaphragmatic surgery and pleurodesis (16 patients). RESULTS: There were differences in BMI and smoking habits between the two groups. The right diaphragm was involved more often (6vs15, p = 0.190). VATS was the preferred surgical approach and only one conversion occurred in the diaphragmatic surgery group (p = 0.470). Diaphragmatic abnormalities were present in all the patients, brown/violet spots (100%) in the pleurodesis group and perforations (100%) in the diaphragmatic surgery group (p < 0.001). There were no differences in days of chest tube removal and length of stay. The recurrence rate was 100% in the pleurodesis alone group while it was only 12.5% in the diaphragmatic surgery group (< 0.001). CONCLUSIONS: In our experience, diaphragmatic surgery and pleurodesis followed by hormonal therapy was an effective approach in preventing recurrence in patients with catamenial pneumothorax and diaphragmatic involvement.

Foreign bodies in the pulmonary circulation have been documented in the literature, with almost all cases being iatrogenic, involving venous catheters, or due to penetrating foreign body emboli. Foreign body pulmonary emboli are often difficult to diagnose due to their varied clinical presentation, the nature of the embolizing material and dubious radiological features. We describe the case of a patient who experienced episodes of massive hemoptysis with inconclusive radiological findings, who underwent a thoracotomy with the discovery of a wooden object of 7 cm in length in the right lower lobe artery, with no apparent mechanism of injury.

PURPOSE: Post-sternotomy dehiscence and mediastinitis remains a serious complication in cardiothoracic surgery. The aim of this work is to report our experience over a period of 8 years in the surgical treatment and risk factor analyses of post-sternotomy dehiscence and mediastinitis. METHODS: All patients treated for post-sternotomy dehiscence at our Thoracic Surgery Unit in the last 8 years were retrospectively collected. We identified 237 patients with post-sternotomy dehiscence/mediastinitis. Forty-two patients had simple fractures of the metal steel wires, 61 had an asymmetric sternotomy with multiple sternal fractures, 113 had a symmetric sternotomy with multiple sternal fractures, 14 had a failed Robicsek procedure, and 7 had sternal dehiscence with mediastinal abscess. RESULTS: Different surgical techniques and materials were used to repair the sternum. In 21 patients, the first revision failed and a second reoperation was required. At multivariate analyses, we have identified risk factors for revision failure and in-hospital mortality. Mortality rate was significantly higher in patients who underwent more than one surgical revision (8% vs 19%, p < 0.001). CONCLUSIONS: Patients with sternal dehiscence are very fragile due to multiple preoperative comorbidities as reflected by postoperative morbidity and risk factors for in-hospital mortality. A correct evaluation of the characteristics of sternal dehiscence is important to guide the most appropriate repair strategy. Patients who need repeated sternal revisions had a higher mortality. Further randomized studies are needed to evaluate different techniques and medical devices to define the gold standard procedure to reduce significantly sternal wound complications in high-risk patients as defined by well-known risk factors.
