BACKGROUND Since delta-shaped gastroduodenostomy was introduced, many surgeons have utilized laparoscopic distal gastrectomy (LDG) with totally intracorporeal Billroth I (ICBI) for gastric cancer, because it is expected to have several advantages over laparoscopic-assisted distal gastrectomy with extracorporeal Billroth I (ECBI). In this study, we compared(More)
OBJECTIVE The purpose of this study was to determine the incidence and risk factors of infections associated with implantable venous access ports (IVAPs). MATERIALS AND METHODS From August 2003 through November 2011, 1747 IVAPs were placed in our interventional radiology suite. One hundred forty four IVAPs were inserted in patients with hematologic(More)
In speech recognition for real-world applications, the performance degradation due to the mismatch introduced between training and testing environments should be overcome. In this paper, to reduce this mismatch, we provide a hybrid method of spectral subtraction and residual noise masking. We also employ multiple model approach to obtain improved robustness(More)
PURPOSE To evaluate long-term clinical outcomes and complications of the single-incision technique for implantation of totally implantable venous access ports (TIVAPs) via the axillary vein. MATERIALS AND METHODS A total of 932 TIVAPs were placed in 927 patients between May 2012 and October 2014 using a single-incision technique. Patients included 620 men(More)
PURPOSE To compare the response to transcatheter arterial chemoembolization (TACE) between hepatocellular carcinoma (HCC) with paradoxical uptake on the hepatobiliary phase (HBP) (HCCpara) and HCC with defect on the HBP (HCCdef), and to identify some imaging features that can differentiate between two groups. MATERIALS AND METHODS Ninety-three HCCs from(More)
PURPOSE To evaluate the technical feasibility and safety of a single-incision technique for placement of implantable venous access ports via the axillary vein. MATERIALS AND METHODS Ports were placed in 216 patients between May and October 2012 using a single-incision technique via the axillary vein. Patients included 112 men and 104 women with a mean age(More)
PURPOSE This study was decided to evaluate the impact of diameter and the existences of multiple side holes along the straight portion of double-J ureteral stents (DJUS) on early dysfunction of stents placed for malignant ureteral strictures. METHODS Between April 2007 and December 2011, 141 DJUSs were placed via a percutaneous nephrostomy (PCN) tract in(More)
PURPOSE To evaluate the risk factors for central vein stenosis after placement of the totally implantable venous access ports (TIVPs) and the clinical relevance of this condition in breast cancer patients. MATERIALS AND METHODS TIVPs were placed in 191 women with breast cancer via the internal jugular vein (IJV) from January 2009 to December 2012 (mean(More)
PURPOSE To evaluate the presence and causes of left brachiocephalic vein (LBCV) steno-occlusive lesions in patients with loss of normal waveform in Doppler ultrasound of the left internal jugular vein (LIJV). MATERIALS AND METHODS We performed Doppler ultrasound of both internal jugular veins in 1912 patients who received an implantable venous access port(More)
PURPOSE To evaluate the effect of an inferior vena cava (IVC) filter during aspiration thrombectomy for acute deep vein thrombosis (DVT) in the lower extremity. MATERIALS AND METHODS From July 2004 to December 2013, a retrospective analysis of 106 patients with acute DVT was performed. All patients received an IVC filter and were treated initially with(More)
