[Primary liposarcomas of the digestive tract: Diversity of clinicopathological presentations and diagnostic challenges].

Sarcomas are rare tumours that represent less than 1% of all malignant tumours in adults. Liposarcomas are among the most common malignant mesenchymal tumours. They are preferentially located in the limbs and the retroperitoneum.

Surgical management of diaphragmatic and thoracic endometriosis': A French multicentric descriptive study.

Introduction: Surgical management of Diaphragmatic and thoracic endometriosis (DTE) is still controversial, a thoracic or an abdominal approach can be proposed.

Methods: We conducted a multicentric retrospective study in 8 thoracic, gynecology or digestive surgery units in 5 French university hospitals. The main objective was to review the current management of DTE.

What are the barriers to the completion of a home-based rehabilitation programme for patients awaiting surgery for lung cancer: a prospective observational study.

Objectives: Home-based rehabilitation programmes (H-RPs) could facilitate the implementation of pulmonary rehabilitation prior to resection for non-small cell lung cancer (NSCLC), but their feasibility has not been evaluated. The aim of this study was to identify determinants of non-completion of an H-RP and the factors associated with medical events occurring 30 days after hospital discharge.

Design: A prospective observational study.

Esophageal emergencies: WSES guidelines.

The esophagus traverses three body compartments (neck, thorax, and abdomen) and is surrounded at each level by vital organs. Injuries to the esophagus may be classified as foreign body ingestion, caustic ingestion, esophageal perforation, and esophageal trauma. These lesions can be life-threatening either by digestive contamination of surrounding structures in case of esophageal wall breach or concomitant damage of surrounding organs.

Operation and Chemotherapy: Prognostic Factors for Lung Cancer With One Synchronous Metastasis.

Background: Stage IV non-small cell lung cancer (NSCLC) is considered incurable; however, some patients with only few metastases may benefit from treatment with a curative intent. We aimed to identify the prognostic factors for stage IV NSCLC with synchronous solitary M1.

Methods: A database constructed from our weekly multidisciplinary thoracic oncology meetings was retrospectively screened from 1993 to 2012.

Ischemic Gastric Conditioning by Preoperative Arterial Embolization Before Oncologic Esophagectomy: A Single-Center Experience.

Purpose: Surgical esophagectomy is the gold standard treatment of early-stage esophageal cancer. The procedure is complicated with significant morbidity; the most severe complication being the anastomotic leakage. Anastomotic fistulas are reported in 5-25% of cases and are mainly due to gastric transplant ischemia.

Medical and Economic Evaluation of FOREseal Bioabsorbable Reinforcement Sleeves Compared With Current Standard of Care for Reducing Air Leakage Duration After Lung Resection for Malignancy: A Randomized Trial.

Objective: The objective of this study was to determine the efficacy of alginate staple-line reinforcement of fissure openings as compared with stapling alone, with or without tissue sealant or glue, in reducing the incidence and duration of air leakage after pulmonary lobectomy for malignancy.

Summary Background Data: No randomized trial evaluating alginate staple-line reinforcement has been performed to date.

Methods: The Staple-line Reinforcement for Prevention of Pulmonary Air Leakage study was a multicenter randomized trial, with blinded evaluation of endpoints.

External validation of a risk score in the prediction of the mortality after esophagectomy for cancer.

This study was designed as an external evaluation of the Steyerberg score in the prediction of different categories of postoperative mortality after esophagectomy on a large nationwide database of thoracic surgeons. Data collection was obtained from the Epithor national database encompassing the majority of thoracic procedures performed in France. We retrospectively compared the predicted to the observed postoperative 30-day (30DM), 90-day (90DM) and in-hospital mortality (IHM) rate in each decile of equal patient.

Covered Stent and Coils Embolization of a Pulmonary Artery Pseudoaneurysm After Gunshot Wound.

We report the first case of endovascular covered stent implantation for the treatment of a large pulmonary artery pseudoaneurysm (PAPA) following a right thoracic gunshot wound. After resuscitation and hemodynamic stabilization, a CT angiography was performed to analyze the neck size of the PAPA and its position relative to the branches of the parent artery. Covered stent implantation with additional coil embolization was successfully performed.

A Giant Purely Polypoid Esophageal Leiomyoma.

We present a case of a giant (13-cm length) purely polypoid esophageal leiomyoma without any intramural development. This form of leiomyoma is rare and develops due to proliferation originating from the muscularis mucosae, although the intramural type originates in the muscularis propria. This should not be confused with giant fibrovascular polyps, which are postulated to arise at the pharyngoesophageal junction when a flap of mobile, redundant submucosa prolapses distally and may cause asphyxia when protruding into the mouth.

Ectopic activation of germline and placental genes identifies aggressive metastasis-prone lung cancers.

Activation of normally silent tissue-specific genes and the resulting cell "identity crisis" are the unexplored consequences of malignant epigenetic reprogramming. We designed a strategy for investigating this reprogramming, which consisted of identifying a large number of tissue-restricted genes that are epigenetically silenced in normal somatic cells and then detecting their expression in cancer. This approach led to the demonstration that large-scale "off-context" gene activations systematically occur in a variety of cancer types.

Endobronchial tumours in a campaign for early detection of bronchial cancer: Computed tomography versus endoscopy.

Objective: To study endobronchial cancers occurring in a population at high risk of bronchial cancer (history of surgically treated bronchial or ENT cancer in complete remission, and symptoms due to smoking) detected by annual volume CT scans and biannual fibroscopy.

Material And Methods: Two hundred and sixty-six patients were included in this single centre prospective study; 27 bronchopulmonary cancers were detected. Ten endobronchial cancers (37%) were identified by fibroscopy (nine invasive cancers and one carcinoma in situ) in 10 patients (nine men) (51-78 years old) nine of whom were smokers (dark tobacco: seven).

Successful treatment of a life-threatening air leakage, complicating severe abdominal sepsis, with a one-way endobronchial valve.

A 41-year-old woman had a jeopardizing air leak from an alveolar-pleural and transdiaphragmatic fistula with pulmonary cavitation, secondary to a severe postoperative abdominal sepsis. Her condition dramatically improved by introduction, in the lower bronchus, of a one-way endobronchial valve, leading to immediate cessation of air leakage and removal of extracorporeal membrane oxygenation, and thus avoiding a lower left lobectomy with myoplasty. Furthermore, removal of the valve nine weeks later led to near-complete recovery of the left lower lobe.

Extraction of substernal goitre using an innovative vacuum device.

The extraction by cervicotomy of substernal goitres may be impossible and sometimes requires the enlargement of the thoracic inlet with at least a sternal-split. We present the extraction of a posterior mediastinal substernal goitre with the application of an innovative vacuum-based suction device, previously used for the control of bleeding from the heart and great vessels in clinical and experimental conditions.

Primary lung adenocarcinoma: characteristics by smoking habit and sex.

The incidence of adenocarcinoma is increasing, particularly among females. We sought to assess the role of tobacco consumption in clinical presentation according to sex. In this retrospective study, 848 patients diagnosed between 1997 and 2006 at Grenoble University Hospital (Grenoble, France) were stratified into four groups according to smoking habits.

Endobronchial closure of bronchopleural fistula with Amplatzer PFO device.

Bronchopleural fistula (BPF) is a feared postoperative complication of pneumonectomy that carries significant morbidity and mortality. BPF can be treated by various surgical and medical techniques. Endobronchial techniques have been used for the delivery of biological glue, sealants, coils, and covered stents with variable degrees of success, depending on the size of the fistula.
