The authors report the case of a 28-year-old female patient with a giant cell tumor originating from the rib. The tumor, measuring 25 x 17 cm, occupied the entire hemithorax and caused atelectasis of the left lung. This tumor was a benign mesenchymal neoplasm, which rarely affects the ribs. A thoracotomy involving en bloc resection of the chest wall and tumor was performed. Despite the large di...

statement of problem: the goal of a successful endodontic surgery is to establish an adequate seal in apical region. therefore during surgery, root-end resection is essential for an appropriate situation and proper access.purpose: the aim of this study was to determine the most appropriate root-end resection angle to establish adequate apical seal in periapical surgerymaterials and methods: for...

BACKGROUND/AIM The outcome of patients with malignant tumors is poor if they suffer from lung metastases. Myeloid-derived suppressor cells (MDSCs), a major player for tumor-induced immunosuppression, can be suppressed by certain chemotherapeutic agents, such as low-dose 5-fluorouracil (5-FU) or surgical treatment. Based on these findings, we hypothesized that early-phase treatment by low-dose 5...

BACKGROUND Video-assisted thoracoscopic surgery (VATS) is widely performed in patients with resectable non-small cell lung cancer. However, it is unknown whether VATS sublobar resection has advantages compared with VATS lobectomy in preserving pulmonary function. METHODS Three hundred patients with non-small cell lung cancer who underwent VATS were enrolled. Pulmonary function tests were perf...

INTRODUCTION Acute respiratory dysfunction syndrome (ARDS), defined as acute hypoxemia accompanied by radiographic pulmonary infiltrates without a clearly identifiable cause, is a major cause of morbidity and mortality after pulmonary resection. The aim of the study was to determine the pre and intraoperative factors associated with ARDS after pulmonary resection retrospectively. METHODS Pati...

OBJECTIVE Lung cancer located in the paravertebral region occasionally invades the rib head (T3) and not the spine (T4). In such cases, a costotransverse ligament release (CTLR) method may be useful for complete resection without performing a vertebrectomy. METHODS Eighteen patients with lung cancer underwent chest wall resection between 2001 and 2009 at our institutions. Of those, 7 who unde...

Background Acute massive hemoptysis is a life-threatening condition. Traditionally, bronchial artery embolization and lung resection are the treatment options. But there is high recurrence rate after bronchial artery embolization and some patients are not suitable for or can’t tolerate lung resection. We develop thoracoscopic bronchial artery ligation as another treatment option. This is the fi...
