In pulmonary surgical practice, appropriate pain management after thoracotomy is essential for patient recovery and the prevention of complications. Although epidural analgesia (EPI) has been established for chest surgery, it has some limitations and contraindications. Recently, paravertebral block (PVB) was reported as a good alternative method with fewer(More)
The diagnostic accuracy of bronchoscopy for detecting lung cancer, especially peripheral lung cancer with lesions outside the endoscopically visible range, remains unsatisfactory. The aim of this study was to perform next-generation sequencing on bronchoscopic specimens to determine whether this improves the accuracy of bronchoscopy for diagnosing lung(More)
BACKGROUND Cardiac hemangiomas are rare benign vascular tumors that can occur in any cardiac layer: endocardium, myocardium, or epicardium. Histologically, cardiac hemangiomas may be classified as capillary, cavernous, or arteriovenous; venous hemangiomas are extremely rare. CASE PRESENTATION A 46-year-old man reported experiencing precordial discomfort.(More)
Stereotactic radiotherapy (SRT) for inoperable stage I non-small cell lung cancer has shown promising results and is now an alternative therapy for this disease. Several reports have detailed changes in mutation profiles after treatment with chemotherapy; however, such changes after SRT for lung cancer have not been reported. A patient who received SRT for(More)
INTRODUCTION A spontaneous mesenteric hematoma is a rare condition. Furthermore, it is extremely rare that the mesenteric hematoma caused gastrointestinal bleeding with an unknown etiology. We experienced a case with a spontaneous mesenteric hematoma that ruptured into the jejunum. PRESENTATION OF CASE A 75-year-old man was referred to our hospital(More)
In cases of multiple lung cancers, individual tumors may represent either a primary lung cancer or both primary and metastatic lung cancers. Treatment selection varies depending on such features, and this discrimination is critically important in predicting prognosis. The present study was undertaken to determine the efficacy and validity of mutation(More)
In thoracic surgery, a thoracic drain is always inserted after the surgical procedure. Repair of the wound after removal of the thoracic tube is performed postoperatively, but no universally standard methods currently exists for this tube removal. Here we report a technique using triclosan-coated sutures that is used in thoracic surgery in our hospital.(More)
Circulating tumor DNA (ctDNA), extracted from plasma, is a non-invasive surrogate biomarker. However, the distribution of ctDNA in the body still remains to be elucidated. In this study, resected lung tumors, with simultaneous blood and bone marrow samples, were analyzed to elucidate the distribution of ctDNA. Rib bone marrow, pulmonary venous blood (Pul.V)(More)
BACKGROUND Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a useful and less invasive procedure for the definitive diagnosis of mediastinal and hilar lymph nodes. However, infectious complications can occur after EBUS-TBNA, although they are extremely rare. CASE PRESENTATION A 66-year-old man with necrotic and swollen lower(More)
