AIM To investigate the early upper gastrointestinal endoscopy (endoscopy) significantly reduces mortality resulting from upper gastrointestinal (GI) bleeding. METHODS Upper GI bleeding was defined as 1a, 1b, 2a, and 2b according to the Forrest classification. The hemoglobin (Hb), and C-reactive protein (CRP) were examined at around the day of endoscopy(More)
BACKGROUND/AIMS To clarify the usefulness of screening ultrasonography (US) to diagnose gastric and colorectal cancer, patient records were analyzed retrospectively. METHODOLOGY Ultrasonography was performed for patients with abdominal symptoms. They were then subjected to computed tomography (CT) when diagnosed with gastric cancer, colorectal cancer, or(More)
BACKGROUND/AIMS The aim of this study was to identify factors affecting the detection of colorectal cancer (CRC) and colon polyps (CPs) using abdominal ultrasonography (US). METHODOLOGY Patient records were analyzed retrospectively. Those diagnosed as having either CRC or CPs by colonoscopy performed after screening abdominal US were enrolled. The(More)
We report a simultaneous operated case of a 73-year-old man with aortic arch aneurysm and squamous cell carcinoma of the lung. Via median sternotomy, aneurysmectomy and graft replacement was performed under hypothermic circulatory arrest and selective brain perfusion. After changing the position, left upper lobectomy with lymph node dissection was performed(More)
To clarify the correlation between the expression level of thymidine phosphorylase (TP) and efficacy of doxifluridine (5'-DFUR) and 5-fluorouracil (5-FU), samples from 177 colorectal cancer patients who underwent curative resection were evaluated by immunohistochemical staining using a newly developed monoclonal antibody 1C6-203. Patients were randomly(More)
AIM To distinguish upper from lower gastrointestinal (GI) bleeding. METHODS Patient records between April 2011 and March 2014 were analyzed retrospectively (3296 upper endoscopy, and 1520 colonoscopy). Seventy-six patients had upper GI bleeding (Upper group) and 65 had lower GI bleeding (Lower group). Variables were compared between the groups using(More)
AIM To examine characteristics of patients with blood urea nitrogen (BUN) levels higher and lower than the normal limit. METHODS Patient records between April 2011 and March 2014 were analyzed retrospectively. During this time, 3296 patients underwent upper endoscopy. In total, 50 male (69.2 ± 13.2 years) and 26 female (72.3 ± 10.2 years) patients were(More)
In a clinical setting, it is important to diagnose complications of acute cholecystitis accurately. Diffusion-weighted whole body imaging with background body signal suppression/T2-weighted image fusion (DWIBS/T2) provides high signal intensity with a strong contrast against surrounding tissues in anatomical settings. In the present study, patients who were(More)
Diffusion-weighted whole-body imaging with background body signal suppression/T2 image fusion (DWIBS/T2) strongly contrasts cancerous tissue against background healthy tissues. Positron emission tomography/computed tomography (PET/CT) applies the uptake of 18-fluorodeoxyglucose in the diagnosis of cancer. Our aim was to compare DWIBS/T2 and PET/CT in(More)
Diffusion-weighted whole-body imaging with background body signal suppression (DWIBS) images show significant contrast for cancer tissues against non-cancerous tissues. Fusion of a DWIBS and a T2-weighted image (DWIBS/T2) can be used to obtain functional, as well as anatomic, information. In the present study, the performance of DWIBS/T2 in the diagnosis of(More)
