BACKGROUND Gastric subepithelial tumors are usually asymptomatic and observed incidentally during endoscopic examination. Although most of these tumors are considered benign, some have a potential for malignant transformation, particularly those originating from the muscularis propria layer. For this type of tumor, surgical resection is the standard(More)
AIM To identify the feasibility of the narrow-band imaging (NBI) method compared with that of conventional colonoscopy and chromoendoscopy for distinguishing neoplastic and nonneoplastic colonic polyps. METHOD This study enrolled consecutive patients who underwent colonoscopy using a conventional colonoscope between January and February 2006 at Chang-Gung(More)
BACKGROUND Surgery of gastrointestinal stromal tumors (GISTs) has been modified, and laparoscopic resection of GIST has gained improvement and roles. PATIENTS AND METHODS We retrospectively reviewed clinical data and oncological outcomes of our GIST patients who underwent laparoscopic surgery and traditional open surgery. In total, 227 pathologically(More)
To identify putative tumor suppressor genes in hepatocarcinogenesis, we combined the representational difference analysis and reverse northern blot identifying downregulated genes in human hepatoma tissues. One of them was Dkk-3/REIC. Dkk-3/REIC was downregulated in 11 out of the 20 human hepatoma tissues as compared to their counterparts of noncancerous(More)
AIM To analyze the predictive factors for lymph node metastasis (LNM) in early gastric cancer (EGC). METHODS Data from patients surgically treated for gastric cancers between January 1994 and December 2007 were retrospectively collected. Clinicopathological factors were analyzed to identify predictive factors for LNM. RESULTS Of the 2936 patients who(More)
BACKGROUND AND AIM Gallbladder (GB) polyps are tumor or tumor-like projections arising from GB mucosa. Although most polyps are benign, some early GB carcinomas present as polypoid lesions. The diagnosis of GB polyps is relatively easy by ultrasonography. Although numerous studies have investigated GB polyps, few studies have addressed the prevalence of and(More)
OBJECTIVES There is no reliable parameter to predict the late mortality of patients with severe acute pancreatitis though it is an important issue. Recently a proposed parameter for "immunoparalysis," a down-regulation of Human Leukocytes Antigens-DR (HLA-DR) expression on monocytes, had been detected in patients with severe but not mild acute pancreatitis.(More)
BACKGROUND & AIMS There is no agreement as to whether F-18 fluorodeoxyglucose positron emission tomography and computed tomography (FDG PET/CT) screening for advanced colorectal neoplasms is meaningful. This retrospective study was undertaken to determine whether FDG PET/CT may be a valuable screening tool for the detection of advanced colorectal neoplasms.(More)
Cirrhotic patients admitted to the medical intensive care unit (ICU) are associated with high mortality rates. The prognosis of critically ill cirrhotic patients is determined by the extent of hepatic and extrahepatic organ dysfunction. This study was conducted to assess and compare the accuracy of the Child-Pugh classification and APACHE II scores,(More)
GOALS This study was conducted to assess and compare the accuracy of Child-Pugh classification and organ system failure (OSF) scores, obtained on the first day of ICU admission, in predicting the hospital mortality in critically ill cirrhotic patients. BACKGROUND Cirrhotic patients admitted to the medical intensive care unit (ICU) are associated with high(More)
