BACKGROUND Peroral cholangioscopic lithotomy is an effective treatment for extrahepatic bile duct stones. However, an evaluation of the usefulness and long-term results of peroral cholangioscopic lithotomy for hepatolithiasis has not been reported. The aim of this study was to evaluate the usefulness and long-term results of peroral cholangioscopic(More)
BACKGROUND AND AIM The aim of the present study was to determine whether additional intraductal ultrasound (IDUS) to confirm complete stone clearance decreases the recurrence rate of common bile duct stones for a 3-year period after endoscopic papillotomy (EPT). METHODS IDUS was carried out with a thin-caliber ultrasonic probe (diameter 2.0 mm, frequency(More)
BACKGROUND Long-term hemodynamic effects and clinical outcomes after balloon-occluded retrograde transvenous obliteration (B-RTO) remain unclear. The purpose of this study was to evaluate long-term clinical results and effects on portal hemodynamics after B-RTO for the treatment of gastric varices with spontaneous gastrorenal shunt. METHODS A total of 21(More)
Pluripotent stem cells, such as embryonic stem cells and induced pluripotent stem (iPS) cells, are regarded as new sources for cell replacement therapy. These cells can unlimitedly expand under undifferentiated conditions and be differentiated into multiple cell types. Automated culture systems enable the large-scale production of cells. In addition to(More)
Venous aneurysm not associated with other cardiovascular disease or trauma is a rare condition. A case is presented of bilateral jugular and mediastinal venous aneurysm, which was detected and depicted to a full extent by means of a blood-pool study with 99mTc-fibrinogen, undertaken because of concurrent thrombocytopenia. The aneurysm was confirmed by(More)
To the Editor: Summadex is a muscle relaxant antagonist that reverses muscle relaxation by binding to muscle relaxants. There is almost no known noteworthy adverse reaction to this drug, although there have been some reports of QT prolongation on electrocardiogram (ECG) induced by summadex [1–3]. We recently encountered a case who developed seconddegree(More)
We have developed a gait rehabilitation robot for hemiplegic patients using the treadmill. A walk phase, which includes time balance of stance and swing legs, is one of the most basic indexes to evaluate patients' gait. In addition, the walking phase is one of the indexes to control our robotic rehabilitation system. However, conventional methods to measure(More)
To develop a gait rehabilitation robot for hemiplegic patients, quantitative evaluations of patient ability is needed. Patient's walk phase, which includes time balance of stance and swing legs, is one of the most useful indexes. However, conventional methods measuring walk phase require laborious preparations. In this paper, a novel algorithm estimating(More)
