BACKGROUND Submucosal tumors often are found incidentally at upper endoscopy. Although the majority of the ones less than 5 cm in size are benign, periodic monitoring for incremental changes in size, which can be stressful and bothersome to patients, is essential. If relatively easy and safe, an endoscopic method of removal would be optimal treatment.(More)
BACKGROUND After acute myocardial infarction (AMI), diastolic function assessed by Doppler echocardiography provides important prognostic information that is incremental to systolic function. However, Doppler variables are affected by multiple factors and may change rapidly. In contrast, left atrial (LA) volume is less influenced by acute changes and(More)
AIMS Non-invasive echocardiographic detection of coronary artery disease (CAD), even in left main or three-vessel CAD, usually requires a stress test since regional wall motion abnormalities (RWMA) are not always evident at rest. Strain is a more sensitive parameter of myocardial systolic function and may be abnormal in patients with severe CAD. METHODS(More)
In 2002, the Japan Pancreas Society (JPS) was the first in the world to propose diagnostic criteria for autoimmune pancreatitis (AIP). Since the concept of AIP has changed with the accumulation of AIP cases, the Research Committee of Intractable Pancreatic Diseases (RCIPD) provided by the Ministry of Health, Labour and Welfare of Japan and the JPS issued(More)
[6]-Gingerol, a major phenolic compound derived from ginger, has anti-bacterial, anti-inflammatory and anti-tumor activities. While several molecular mechanisms have been described to underlie its effects on cells in vitro and in vivo, the underlying mechanisms by which [6]-gingerol exerts anti-tumorigenic effects are largely unknown. The purpose of this(More)
The surgical resection of hilar cholangiocarcinoma is extremely challenging because the tumor is closely related with the complicated hilar structures. We investigated to identify the outcomes for patients who underwent surgical resection and to identify the parameters that influenced radical resection. From January 2000 to December 2009, 105 patients(More)
Endoscopic papillary balloon dilation (EBD) for choledocholithiasis is known to be comparable to endoscopic sphincterotomy (EST) especially in cases of small stones. With larger stones, EBD with conventional balloon, which have a diameter of 6-8 mm, was reported as less effective for extraction of stones. We evaluated the efficacy and complications of EBD(More)
OBJECTIVE To analyze the computed tomography (CT) findings of fatty replacement in the right ventricle (RV) of asymptomatic subjects and to correlate the CT findings with electrocardiogram (ECG) abnormalities. METHODS This prospective study included 996 subjects who underwent ECG-gated 16-slice CT for determination of coronary calcium scores. The CT(More)
BACKGROUND AND OBJECTIVES The objective of this study was to analyze the survival outcome and the clinicopathological factors that influence survival and recurrence of middle and distal bile duct cancer after surgical resection. METHODS From January 2000 to June 2007, 125 patients underwent surgical resection for middle and distal bile duct cancer. The(More)
OBJECTIVES The aim of this study was to define the phenotypic spectrum of apical hypertrophic cardiomyopathy (ApHCM) and clinical characteristics pertaining to identified subtypes. METHODS In 182 consecutive ApHCM patients (58.9 +/- 11.2 years; 142 men) with left ventricular ejection fraction > or =50%, we measured end-diastolic wall thickness of all 16(More)
