OBJECTIVE To determine the safety of laparoscopy-assisted distal gastrectomy (LADG) compared with open distal gastrectomy (ODG) in patients with clinical stage I gastric cancer in Korea. BACKGROUND There is still a lack of large-scale, multicenter randomized trials regarding the safety of LADG. METHODS A large-scale, phase 3, multicenter, prospective(More)
Chronic infection with hepatitis B virus (HBV) is closely associated with the etio-pathogenesis of primary hepatocellular carcinoma (PHC). It has been proposed that infection with HBV early in life, frequently transmitted by an HBV-carrier mother, leads to persistent infection with HBV, which in turn is associated with the development of chronic active(More)
A randomized controlled trial to evaluate the long-term outcomes of laparoscopic distal gastrectomy for gastric cancer is currently ongoing in Korea. Patients with cT1N0M0-cT2aN0M0 (American Joint Committee on Cancer, 6th edition) distal gastric cancer were randomized to receive either laparoscopic or open distal gastrectomy. For surgical quality control,(More)
BACKGROUND Acinar cell carcinoma represents only 1-2% of exocrine pancreatic neoplasms. On exceptionally rare occasions, primary acinar cell carcinoma can occur in ectopic locations. Herein, we report a case of pure pancreatic-type acinar cell carcinoma arising in the stomach. CASE PRESENTATION A 54-year-old male presented with a gastric submucosal mass(More)
The aim of this study was to compare the diagnostic performance of gadobenate dimeglumine (Gd-BOPTA)-enhanced MR imaging, including dynamic phases and one-hour delayed phase, versus superparamagnetic iron oxide (SPIO)-enhanced imaging for detection of liver metastases. Twenty-three patients with 59 liver metastases underwent Gd-BOPTA-enhanced MR imaging(More)
PURPOSE SIRT1 (silent mating-type information regulation 2 homologue 1) expression has been reported to predict poor survival in some cancers. We therefore investigated the expression levels of SIRT1 and its negative regulator, DBC1 (deleted in breast cancer 1), in gastric cancer patients. EXPERIMENTAL DESIGN We evaluated immunohistochemical expression of(More)
Large cell neuroendocrine carcinomas (LCNECs) of the stomach are rare and represent only a small percentage of all gastric endocrine tumors. Here we report a case of a rare combination of gastric LCNEC concurrent with gastric adenocarcinoma. A 50-year-old man presented with heartburn sensation for 2 weeks. An endoscopic evaluation revealed a relatively(More)
Glutamine, traditionally a non-essential amino acid, now has been considered as essential in serious illness and injury. It is a major precursor for glutathione synthesis. However, the anti-fibrotic effect of glutamine and its molecular mechanism in experimental liver fibrosis have not been explored. In the present study we aimed to examine the potential(More)
PURPOSE Most stomach surgeons have been educated sufficiently in conventional open distal gastrectomy (ODG) but insufficiently in laparoscopy-assisted distal gastrectomy (LADG). We compared learning curves and clinical outcomes between ODG and LADG by a single surgeon who had sufficient education of ODG and insufficient education of LADG. MATERIALS AND(More)
Inflammation of the asthmatic airway is usually accompanied by increased vascular permeability and plasma exudation. Oxidative stress plays critical roles in airway inflammation. Although reactive oxygen species (ROS) are shown to cause vascular leakage, the mechanisms by which ROS induce increased vascular permeability are not clearly understood. We have(More)
