Pleurectomy and decortication (P/D) improve survival and quality of life in selected patients with malignant pleural mesothelioma. The operative procedure was not standardized until recently. The goal of the operation is to perform a macroscopic complete resection of the tumor. This often involves resection of the parietal and visceral pleura and invariably a partial or complete resection and prosthetic reconstruction of ipsilateral hemidiaphragm. We describe our operative planning and technique as well as outcomes of P/D reported in current literature.

Mesothelioma and Radical Surgery 2 (MARS 2): protocol for a multicentre randomised trial comparing (extended) pleurectomy decortication versus no (extended) pleurectomy decortication for patients with malignant pleural mesothelioma.
INTRODUCTION
Mesothelioma remains a lethal cancer. To date, systemic therapy with pemetrexed and a platinum drug remains the only licensed standard of care. As the median survival for patients with mesothelioma is 12.1 months, surgery is an important consideration to improve survival and/or quality of life. Currently, only two surgical trials have been performed which found that neither extensive (extra-pleural pneumonectomy) or limited (partial pleurectomy) surgery improved survival (although there was some evidence of improved quality of life). Therefore, clinicians are now looking to evaluate pleurectomy decortication, the only radical treatment option left.
METHODS AND ANALYSIS
The MARS 2 study is a UK multicentre open parallel group randomised controlled trial comparing the effectiveness and cost-effectiveness of surgery-(extended) pleurectomy decortication-versus no surgery for the treatment of pleural mesothelioma. The study will test the hypothesis that surgery and chemotherapy is superior to chemotherapy alone with respect to overall survival. Secondary outcomes include health-related quality of life, progression-free survival, measures of safety (adverse events) and resource use to 2 years. The QuinteT Recruitment Intervention is integrated into the trial to optimise recruitment.
ETHICS AND DISSEMINATION
Research ethics approval was granted by London - Camberwell St. Giles Research Ethics Committee (reference 13/LO/1481) on 7 November 2013. We will submit the results for publication in a peer-reviewed journal.

Thoracic endometriosis syndrome is an under-recognised manifestation of endometriosis and includes catamenial pneumothorax, catamenial haemothorax, catamenial haemoptysis and pulmonary nodules. Catamenial pneumothorax presents as recurrent spontaneous pneumothorax with a temporal relationship to the onset of menses, affecting mostly the right lung. A 48-year-old woman presented with an eight-year history of right-sided catamenial pneumothorax, during which time she had three episodes of pneumothorax. Serial chest imaging revealed an enlarging mass overlying the right hemi-diaphragm. She was referred to our trust where she underwent video-assisted thoracoscopic surgery for right pleurectomy. Intraoperatively, defects were found in the right hemidiaphragm, through which parts of the liver had herniated. We describe the presenting features and management of catamenial pneumothorax.

Review
INTRODUCTION
Extrapleural pneumonectomy (EPP) and extended pleurectomy/decortication (ePD) are surgical cytoreductive techniques aimed at achieving macroscopic resection in malignant pleural tumours such as pleural mesothelioma, non-mesothelioma pleural malignancies such as thymoma and sarcoma, and rarely for pleural tuberculosis, in a more limited fashion. Despite extensive studies on both surgical techniques and consequences, a significant knowledge gap remains regarding how best to approach the perioperative anaesthesia challenges for EPP and ePD.It is unknown if the risk stratification processes for such surgeries are standardised or what types of functional and dynamic cardiac and pulmonary tests are employed preoperatively to assist in the perioperative risk stratification. Further, it is unknown whether the types of anaesthesia and analgesia techniques employed, and the types of haemodynamic monitoring tools used, impact on outcomes. It is also unknown whether individualised haemodynamic protocols are used to guide the rational use of fluids, vasoactive drugs and inotropes.Finally, there is a dearth of evidence regarding how best to monitor these patients postoperatively or what the most effective enhanced recovery protocols are to best mitigate postoperative complications and accelerate hospital discharge. To increase our knowledge of the perioperative and anaesthetic treatment for patients undergoing EPP/ePD, this scoping review attempts to synthesise the literature and identify these knowledge gaps.
METHODS AND ANALYSIS
This scoping review will be conducted in accordance with the Preferred Reporting Items for Systematic Review and Meta-Analysis Extension for Scoping Review Protocols methodology. Electronic databases, OVID Medline, EMBASE and the Cochrane Library, will be systematically searched for relevant literature corresponding to EPP or ePD and perioperative or anaesthetic management. Data will be analysed and summarised descriptively and organised according to the three perioperative stages: preoperative, intraoperative and postoperative factors in clinical care.
ETHICS AND DISSEMINATION
Ethics approval was not required. The findings will be disseminated through professional networks, conference presentations and publications in scientific journals.

Minimally invasive repair of pectus excavatum (Nuss) operation is the current choice of surgical treatment for pectus excavatum deformities. Technical pitfalls arise in patients with previous thoracic and/or cardiac surgical interventions, due to severe intrathoracic fibrous adhesions. Herein, we describe an original modification technique in a patient with bilateral apical wedge resection and total pleurectomy due to recurrent spontaneous pneumothorax episodes within the past two years. Correction was performed by opening the pleura bilaterally and retrosternal release with digital palpation via a subxiphoid incision, to help to guide the introducer and the pectus bar, without a videothoracoscopic visualization.

Review
The optimal treatment of malignant pleural mesothelioma (MPM) has not yet been established and is still under investigation. Surgery is one of the pillars in the multimodality approach with the purpose of removing as much as visible tumor as possible and to relieve symptoms. To date, two major surgical procedures are available for removal or debulking of MPM that is considered to be resectable: [extended (e)] pleurectomy/decortication (P/D) and extrapleural pneumonectomy (EPP). Historically, EPP was regarded as the only way to achieve a macroscopic complete resection. However, in the last years, there is a shift in literature towards (e)P/D as the preferred surgical procedure whenever possible as several retrospective studies and meta-analyses showed a similar or lower long-term survival and higher perioperative mortality and postoperative morbidity in patients who been treated with EPP. On the other hand, no randomized-controlled trials regarding surgical treatment with (e)P/D or EPP exist and therefore level A evidence favoring one surgical procedure is lacking. In this review we provide a nuanced and well-considered answer to the question whether EPP is still indicated in the surgical treatment of MPM.

Review
Surgical intervention plays an important role in the diagnosis, staging, and treatment of malignant pleural mesothelioma (MPM) and can be applied with curative or palliative intent. The overall aim of surgery should be, as in any oncologic surgery, the macroscopic complete resection (MCR) of the tumor. Most importantly, the majority of patients with the diagnosis of MPM should be appropriately staged and initially evaluated in a multidisciplinary setting, including medical oncology, radiation oncology, and surgery after histologic diagnosis. Surgical staging, including determination of the histologic subtype and lymph node status, as well as clinical staging with positron-emission tomography-computer tomography scan and determination of cardiopulmonary reserve are crucial. Herein, we summarize the role of surgical resection, specifically macroscopic complete resection, performed as extrapleural pneumonectomy or extended pleurectomy/decortication in multimodality treatment settings and advocate for optimal patient selection for one or the other procedure. In addition, the roles of surgery in diagnosis of MPM and in palliative care are discussed.

Review
Surgery plays a central role in the diagnosis, staging, and management of pleural mesothelioma. Achieving an accurate diagnosis through surgical intervention and identifying the specific histologic subtype is crucial for determining the appropriate course of treatment. The histologic subtype guides decisions regarding the use of chemotherapy, immunotherapy, or multimodality treatment. The goal of surgery as part of multimodality treatment is to accomplish macroscopic complete resection with the eradication of grossly visible and palpable disease. Over the past two decades, many medical centers worldwide have shifted from performing extra-pleural pneumonectomy (EPP) to pleurectomy decortication (PD). This transition is motivated by the lower rates of short-term mortality and morbidity associated with PD and similar or even better long-term survival outcomes, compared to EPP. This review aims to outline the role of surgery in diagnosing, staging, and treating patients with pleural mesothelioma.

BACKGROUND
Treatment of malignant pleural mesothelioma (MPM) represents a major challenge for oncologists. Multimodality treatment, which generally involves induction chemotherapy, surgery and radiotherapy have recently shown promising results. The aim of this study was to evaluate the locoregional control and toxicity of intensity modulated radiotherapy (IMRT) after pleurectomy and decortication (P/D) as part of trimodality therapy for patients with locally advanced MPM.
METHODS
We prospectively analyzed data from 20 patients with MPM treated at a single tertiary-care institution. Initially every patient received induction chemotherapy with platinum-based chemotherapy. After chemotherapy, patients without progression underwent P/D, and if feasible, hemi-thoracic IMRT was administered at a planned dose of 50.4-54 Gy in 28-30 fractions and treated with 9-11 noncoplanar fields.
RESULTS
A total of 15 of the 20 enrolled patients underwent P/D followed by IMRT to the hemi-thoracic cavity. The median total radiotherapy dose was 48.7 Gy (23.4-54 Gy). Radiation pneumonitis (RP) developed in nine patients (60%), and of these, two patients (13.3%) experienced G3 or G4 RP. The estimated locoregional-relapse-free survival at two years was 75.9%, and the main pattern of recurrence was distant (72.7%). For the entire cohort median follow-up was 22.7 months, median progression-free survival was 18.9 months and median overall survival 23.6 months.
CONCLUSIONS
Platinum-based chemotherapy followed by lung-sparing surgery (P/D) and IMRT is a feasible and safe treatment modality that yields acceptable locoregional control in patients with locally advanced MPM; however, these results should be corroborated in larger studies.

Review
Pleural metastasis is a common occurrence in up to 30% of patients with metastatic cancer. When lung entrapment and loculation of fluid occur, treatment is more difficult and we have named this condition "oncothorax." The malignant adhesions that entrap the lung in an oncothorax are not typically amenable to surgical decortication. The standard approach for managing these patients is to place an indwelling catheter. Other options may include pleurectomy and decortication, intrapleural hyperthermic chemoperfusion, and intrapleural photodynamic therapy. However, these procedures should be provided selectively depending on patient performance status, extent of metastatic disease, and level of experience.
