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)
OBJECTIVES Postoperative myasthenic crisis (POMC) is one of the serious complications after extended thymectomy for patients with myasthenia gravis (MG). This study aims to clarify the risk factors of POMC occurrence. METHODS The clinical data of 55 MG patients (25 male, 30 female; median age, 51 years) who underwent extended thymectomy at Kyoto(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)
Patients with diseases such as chronic obstructive pulmonary disease (COPD) need to improve their thorax mobility. Thoracic ROM is one of the simplest and most useful indexes to evaluate the respiratory function. In this paper, we have proposed the prototype of a simple thoracic ROM measurement system with real-time visual bio-feedback in the chest(More)
