This study was designed to assess the safety of transcatheter arterial embolization (TAE) with n-butyl cyanoacrylate-lipiodol (NBCA-Lp) for the large bowel and to investigate the vital response to NBCA-Lp in a swine model. In nine swine, nine arteries nourishing the colon were embolized with NBCA-Lp (1 ml of NBCA mixed with 4 ml of lipiodol): sigmoid-rectal(More)
The purpose of this study was to evaluate change in the portal systemic pressure gradient (PSPG) following balloon-occluded retrograde transvenous obliteration (BRTO) and the aggravation of esophageal varices. The PSPG was monitored before and after BRTO in 19 patients. PSPG changes were obtained by subtracting the PSPG before BRTO from that after BRTO. The(More)
PURPOSE The aim of this study was to compare the safety and short-term efficacy of transcatheter arterial chemoembolization (TACE) using cisplatin-Lipiodol suspension (CP/Lp) with that using epirubicin-Lipiodol emulsion (EP/Lp) in patients with recurrent hepatocellular carcinoma (HCC). MATERIALS AND METHODS A total of 28 HCC patients were enrolled(More)
Large cell neuroendocrine carcinoma of the gall-bladder is a rare disease in which the prognosis worsens with size. We report a case of large cell neuroendocrine carcinoma of the gallbladder in a 64-year-old woman who presented with a right upper quadrant mass whose longest diameter was 11.5 cm; the mass was initially considered to be unresectable because(More)
PURPOSE To compare the efficacy of transcatheter arterial chemoembolization (TACE) using multiple anticancer drugs (epirubicin, cisplatin, mitomycin C, and 5-furuorouracil: Multi group) with TACE using epirubicin (EP group) for hepatocellular carcinoma (HCC). MATERIALS AND METHODS The study design was a single-center, prospective, randomized controlled(More)
Paraaortic lymph nodal (PALN) recurrence is not a rare scenario of abdominal malignancies including pancreas cancer, even after radiotherapy. The role and indication of reirradiation is limited because it is often associated with significant late toxicity in the surrounding normal organs. We developed a new approach and technique of brachytherapy to(More)
PURPOSE To assess the feasibility and efficacy of single photon emission computed tomography-based three-dimensional conformal radiotherapy (SPECT-B 3D-CRT) for large hepatocellular carcinoma (HCC) with portal vein tumor thrombus (PVTT). METHODS AND MATERIALS HCC patients with PVTT in the first branch or main trunk, 8 cm or greater in size, were admitted(More)
PURPOSE To evaluate the safety and efficacy of three-dimensional conformal radiotherapy (3D-CRT) using single photon emission computed tomography (SPECT) in unresectable hepatocellular carcinoma (HCC) with portal vein tumor thrombus (PVTT). METHODS AND MATERIALS Patients with HCC with PVTT in the first branch and/or main trunk were selected for this(More)
INTRODUCTION Reirradiation of locally recurrent prostate cancer after radiotherapy is limited because of its toxicity to the rectum that is closely adjacent to the prostate. To solve geometric anatomic constraints, including rectal size and distance from the prostate, we developed a technique that modifies the geometry by noninvasive direct intervention. (More)
