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: 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)
OBJECTIVES To present the technique of single-port video-assisted thoracoscopic mediastinal tumour resection, which includes limited thymectomy, extended thymectomy, cyst excision and posterior mediastinal tumour excision, and the early results of resection with the use of this technique. METHODS Twenty-nine patients with mediastinal tumours were treated(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)
BACKGROUND Natural orifice transluminal endoscopy has been developed for abdominal surgical procedures. The aim of this study was to compare the surgical outcome between a novel transoral approach and a standard transthoracic approach for the thoracic cavity in a canine model. METHODS Twenty-eight dogs were assigned to transoral (n = 14) or standard(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)
Major vessel (aorta or iliac vessels) injury is a rare yet catastrophic complication of spinal surgery. Prompt diagnosis is vital for effectively treating these injuries. A 56-year-old female with iliac artery iatrogenic injury during lumbar discectomy was successfully treated by percutaneous placement of a self-expanding stent graft in an emergent setting(More)
