Background: Patients undergoing an unsuccessful sympathectomy experience dryness on one hand and excessive sweating on the other. This is embarrassing for the patients, and resolution of both a previous failed sympathectomy and recurrent hyperhidrosis is important. Methods: From September 1995 to January 1998, 24 patients (11 men and 13 women; mean age,(More)
Intravenous ports are widely used for oncology patients. However, catheter fractures may lead to the need for re-intervention. We aimed to identify the risk factors associated with catheter fractures. Between January 1 and December 31, 2006, we retrospectively reviewed the clinical data and plain chest films of 1,505 patients implanted with an intravenous(More)
BACKGROUND The thoracic cavity approach for natural orifice transluminal endoscopic surgery (NOTES) is technically challenging. The aim of this study was to evaluate the feasibility of a transoral endoscopic technique for a surgical lung biopsy and pericardial window creation METHODS Under general anesthesia, a 12 mm incision was made over the vestibulum(More)
This study aimed to determine the feasibility of a novel transtracheal endoscopic technique for thoracic and mediastinum evaluation in a canine model. In two dogs under general anesthesia, a transverse incision was made in the right lateral wall of the lower trachea and used as an entrance for thoracic and mediastinum evaluation. Transtracheal thoracoscopic(More)
BACKGROUND To date there are no practical platforms for performing natural orifice transluminal endoscopic surgery in the thoracic cavity. This study evaluates the feasibility of transumbilical thoracosopy for lung biopsy and pericardial window creation. METHODS Eleven dogs (6 in the nonsurvival group and 5 in the survival group) were used for this study.(More)
Single-port video-assisted thoracoscopic surgery (VATS) has been widely applied recently. However, there are still only few reports describing its use in mediastinum tumor resection. We present the technique of single-port video-assisted thoracoscopic mediastinum tumor resection and compare it with conventional VATS with regard to short-term outcome.We(More)
With regard to pathologic stage IIA (pIIA) non-small cell lung cancer (NSCLC), there is a paucity of literature evaluating the risk factors for disease-free survival (DFS) and overall survival (OS). The aim of this study was to identify the prognostic factors of DFS and OS in patients with NSCLC pIIA.We performed a retrospective review of 98 stage II(More)
RATIONALE AND OBJECTIVES Research suggests that the semiquantitative determination of nodal (18)F-fluorodeoxyglucose (FDG) uptake on positron emission tomography (PET)/computed tomography (CT) may be useful for the assessment of mediastinal metastases in patients with non-small-cell lung carcinoma (NSCLC). The aim of this study was to evaluate the(More)
The benefit of bullae ablation for the management of primary spontaneous pneumothorax (PSP) has been established. However, various modalities for bullae ablation have been reported from different centers. The present study aimed to assess whether endoloop ligation of bullae was as effective as staple bullectomy for preventing the recurrence of pneumothorax.(More)
This study evaluated the use of intravenous ports and provides a guide related to clinical decision making. This study retrospectively reviewed 1505 patients who had received intravenous ports at Chang Gung Memorial Hospital in 2006. The relationships between the complications and entry routes were assessed. The intervention-free periods were also(More)
