[Probable Immunoglobulin G4 (IgG4)-related Periaortitis Requiring Differentiation from Mediastinal Tumor].

A 42-year-old man with a history of suspected of Behcet's disease underwent oral steroid treatment. During follow-up, chest X-ray revealed an abnormal shadow of the mediastinum. Chest computed tomography(CT) showed a circumferential tumor around the descending thoracic aorta.

Pulmonary metastasectomy is associated with prolonged survival among patients with bone and soft tissue sarcoma.

The aim of the present study was to evaluate the survival impact of surgical resection among patients with pulmonary metastases from bone and soft tissue sarcomas. A total of 34 consecutive patients with ≤5 pulmonary metastases from bone and soft tissue sarcomas were retrospectively reviewed. The patients included 19 men and 15 women, with a median age of 64.

[Paraffinoma with Spinal Paralysis 40 Years After Pleural Plombage for Tuberculosis].

Paraffin had been used for pleural plombage in the treatment of tuberculosis. However, paraffin use has been reported to cause late postoperative complications. A 79-year-old man was presented with an extramedullary tumor and spinal paralysis.

Outcomes of completion lobectomy long after segmentectomy.

Background: Completion lobectomy long after segmentectomy in the same lobe is extremely difficult because of severe adhesions around hilar structures, especially in cases involving video-assisted thoracoscopic surgery (VATS) completion lobectomy. We report and compare the surgical outcomes of patients who underwent VATS or thoracotomy completion lobectomy long after radical segmentectomy for lung cancer.

Methods: We retrospectively evaluated the surgical outcomes of completion lobectomies performed at our institute long after radical segmentectomies for lung cancer in the same lobe.

Quality assessment using EQ-5D-5L after lung surgery for non-small cell lung cancer (NSCLC) patients.

Objectives: Aim of this study was to elucidate an alteration of quality of life (QOL) score before and after video-assisted thoracoscopic surgery (VATS) for non-small cell lung cancer (NSCLC) patients using the 5-level EuroQol-5D questionnaire (EQ-5D-5L). We also investigated how the preoperative QOL scores affected the postoperative clinical outcome prospectively.

Methods: Between July 2018 and December 2018, 24 consecutive NSCLC patients who underwent VATS were recruited.

[Surgical Treatment for Pneumopyothorax Secondary to Pancreatic Fistula].

A 46-year-old woman with cervical cancer with multiorgan metastasis visited our hospital. She underwent a total gastrectomy, splenectomy, distal pancreatectomy, left adrenalectomy, and left partial diaphragmatic resection. Postoperatively, she developed pleural effusion with high level of amylase secondary to a pancreatic fistula, consequently causing left-sided empyema.

Left upper pulmonary vein connected to the persistent left superior vena cava and the left atrium.

Persistent left superior vena cava (PLSVC) is the most common anomalous thoracic venous drainage. A PLSVC usually drains into the right atrium through a dilated coronary sinus. It is rare that a PLSVC flows directly into the left atrium, and even rarer that it connects to the left upper pulmonary vein (LUPV).

Thoracoscopic Right Basilar Segmentectomy After Right Upper Lobectomy.

This report describes a case of thoracoscopic right basilar segmentectomy after upper lobectomy. A 76-year-old man who underwent right upper lobectomy for lung tuberculosis 50 years earlier had a diagnosis of squamous cell carcinoma, stage IB (T2a N0 M0), in the right lower lobe and underwent right basilar segmentectomy for limited resection. The postoperative course was uneventful.

Thoracoscopic one-stage lobectomy and diaphragmatic plication for T3 lung cancer.

Background: Combined resection of a phrenic nerve is occasionally required in T3 primary lung carcinomas invading the phrenic nerve to completely remove a malignant tumour, resulting in diaphragmatic paralysis. We describe the first case of thoracoscopic lobectomy and diaphragmatic plication as a one-stage surgery for lung cancer invading the phrenic nerve.

Case Presentation: A 56-year-old woman with a T3N0M0 primary adenosquamous carcinoma in the left upper lobe presented with suspicious invasion to the anterior mediastinal fat tissue and left phrenic nerve and underwent left upper lobectomy, node dissection, and partial resection of the anterior mediastinal fat tissue with the left phrenic nerve.

Relationship between onset of spontaneous pneumothorax and weather conditions.

Objectives: Spontaneous pneumothorax (SP) results from the rupture of blebs or bullae. It has been suggested that changes in weather conditions may trigger the onset of SP. Our aim was to examine the association between the onset of primary SP with weather changes in the general population in Sapporo, Japan.

[Management of Pulmonary Thromboembolism].

Pulmonary thromboembolism is a fatal perioperative complication in general thoracic surgery. There is a report on its incidence of 2.68 cases out of 10,000 general thoracic surgeries.

Video-assisted thoracoscopic surgery node dissection for lung cancer treatment.

Purpose: Mediastinal node dissection (MND) is an integral component of the surgical treatment for non-small cell lung cancer (NSCLC). Although video-assisted thoracoscopic surgery (VATS) has been used increasingly for lung cancer treatment, the accuracy of by VATS MND still remains controversial. We reviewed the surgical results of VATS MND for NSCLC.

Fibroblastic foci, covered with alveolar epithelia exhibiting epithelial-mesenchymal transition, destroy alveolar septa by disrupting blood flow in idiopathic pulmonary fibrosis.

Idiopathic pulmonary fibrosis (IPF) is a chronic, progressive interstitial lung disease of unknown cause. IPF has a distinct histopathological pattern of usual interstitial pneumonia in which fibroblastic foci (FF) represent the leading edge of fibrotic destruction of the lung. Currently there are three major hypotheses for how FF are generated: (1) from resident fibroblasts, (2) from bone marrow-derived progenitors of fibroblasts, and (3) from alveolar epithelial cells that have undergone epithelial-mesenchymal transition (EMT).

[Pulmonary Carcinoid Tumor with Cushing's Syndrome in a Patient who Underwent Pulmonary Resection by Video-Assisted Thoracic Surgery;Report of a Case].

Pulmonary carcinoid tumor with Cushing's syndrome is comparatively rare disease. It is difficult to make an early diagnosis due to small size lesion in its early stage. We report a case of pulmonary carcinoid tumor with Cushing's syndrome successfully localised by positron emission tomography/computed tomography and was resected in the early stage.

Spontaneous thymic hemorrhage in an adult.

Spontaneous thymic hemorrhage in a normal thymus in neonates and infants has been reported in the literature. Only one case of spontaneous thymic hemorrhage in an adult has been reported to our knowledge. We herein report the case of an adult who had a cardiac operation 26 years previously and who was on anticoagulation.

[Evaluation of long-term results in patients who underwent reconstruction of thoracic wall with curved metal plates].

Between 1992 and 2011, 22 patients underwent surgery of reconstruction of thoracic wall with curved metal plates for multiple rib fracture and resection of thoracic wall tumor. They were divided into 2 groups according to original disorders. Twelve cases of group A accepted surgical stabilization of traumatic multiple rib fractures with the metal plates fixed on the fractured ribs as an external brace.

[Henoch-Schönlein Purpura with lung abscess].

A 72-year-old man had underwent left lower lobectomy for squamous cell carcinoma in our hospital in 2008. Postoperative stage was I A (T1N0M0). In 2010, follow-up chest computed tomography (CT) images showed similar cavitary nodules in segments 2 and 8 of the right lung with positive uptake on fluorodeoxyglucose-positron emission tomography (FDG-PET) images.

[Prognostic factors of resected metastatic lung tumor originated from renal cell carcinoma].

We performed retrospective analysis of 22 cases who received pulmonary resection of metastases originated from renal cell carcinoma between 1997 and 2011. Patients comprised 18 men and 4 women with a mean age of 63 years (range, 39~79). The total pulmonary resection was 30 times, lobectomy was performed 5 times and wedge resection was 25 times.

Surgical treatment for primary lung cancer combined with idiopathic pulmonary fibrosis.

Idiopathic pulmonary fibrosis (IPF) is defined as a specific form of chronic, progressive fibrosing interstitial pneumonia of unknown cause. IPF is associated with an increased risk of lung cancer, and lung cancer patients with IPF undergoing pulmonary resection for non-small cell lung cancer have increased postoperative morbidity and mortality. Especially, postoperative acute exacerbation of IPF (AEIPF) causes fatal status and long-term outcomes are worse than for patients without IPF, although certain subgroups have a good long-term outcome.

Smeloff-Cutter aortic valve endocarditis 31 years after implantation.

A Smeloff-Cutter ball prosthetic valve was replaced in a 56-year-old woman 31 years after implantation. Prosthetic endocarditis developed after endoscopic mucosal resection of colon cancer. The excised aortic ball valve was almost intact, without any thrombus formation.

Is video-assisted thoracoscopic surgery a feasible approach for clinical N0 and postoperatively pathological N2 non-small cell lung cancer?

Objective: It remains controversial whether video-assisted thoracoscopic surgery (VATS) major pulmonary resection (VMPR) with systematic node dissection (SND) is a feasible approach for clinical N0 and pathological N2 non-small cell lung cancer (cN0-pN2 NSCLC). We compared the clinical outcome of patients who underwent VMPR with SND for cN0-pN2 NSCLC with the outcome of patients who underwent MPR with SND by thoracotomy. We conducted this study to determine the feasibility of VMPR for cN0 and pN2 NSCLC patients and intraoperative node staging by node sampling.
