AIM To evaluate the incidence and clinical characteristics of gastric cancer (GC) in peptic ulcer patients with Helicobacter pylori (H. pylori) infection. METHODS Between January 2003 and December 2013, the medical records of patients diagnosed with GC were retrospectively reviewed. Those with previous gastric ulcer (GU) and H. pylori infection were(More)
The aim of the present study was to evaluate the more effective therapy for the postsurgical gastroesophageal leakage by a head-to-head comparison of endoscopic vacuum therapy (EVT) and endoscopic stent implantation with self-expandable metal stent (E-SEMS). In this hospital-based, retrospective, observative study, the patients were classified into 2(More)
AIM To evaluate the efficacy of moxifloxacin-based sequential therapy (MBST) versus hybrid therapy as a first-line treatment for Helicobacter pylori (H. pylori) infection. METHODS From August 2014 to January 2015, 284 patients with confirmed H. pylori infection were randomized to receive a 14-d course of MBST (MBST group, n = 140) or hybrid (Hybrid group,(More)
BACKGROUND/AIMS The aim of this study was to evaluate the ability of Helicobacter pylori eradication treatment to increase platelet counts in Korean patients with chronic idiopathic thrombocytopenic purpura (ITP). METHODS A total of 102 patients were evaluated against two criteria. First, those diagnosed with H. pylori infections in whom eradication was(More)
BACKGROUND Atrophic gastritis is a precancerous condition, which can be diagnosed by several methods. However, there is no consensus for the standard method. The aim of this study was to evaluate the correlations among endoscopic, histologic, and serologic findings for the diagnosis of atrophic gastritis. METHODS From March 2003 to August 2013, a total of(More)
AIM To investigate the eradication rate and histological changes after Helicobacter pylori (H. pylori) eradication treatment following subtotal gastrectomy for gastric cancer. METHODS A total of 610 patients with H. pylori infection who had undergone surgery for either early or advanced gastric adenocarcinoma between May 2004 and December 2010 were(More)
The aim of this study was to identify the risk factors for residual/recurrent tumors in patients with a tumor-positive lateral resection margin (LRM+) after endoscopic resection of early gastric cancer (EGC) and to establish the criteria for performing additional treatment. A retrospective analysis was performed on consecutive patients who underwent(More)
BACKGROUND/AIMS In gastric mucosa-associated lymphoid tissue (MALT) lymphoma, the clinical significance of various endoscopic findings has not yet been determined. This study aimed to compare the time to complete remission (CR) and relapse-free survival (RFS) in gastric MALT lymphoma based on endoscopic findings. METHODS In this single-center(More)
BACKGROUND/AIMS The prevalence of gastroesophageal reflux disease (GERD) is high in patients with idiopathic pulmonary fibrosis (IPF). GERD may cause chronic microaspiration that leads to repeated subclinical lung injury, which leads to pulmonary fibrosis. Although some studies have suggested that proton pump inhibitors (PPI) were associated with a good(More)
BACKGROUND The (13)C-urea breath test ((13)C-UBT) is a noninvasive method for diagnosing Helicobacter pylori (H. pylori) infection. The aims of this study were to evaluate the diagnostic validity of the (13)C-UBT cutoff value and to identify influencing clinical factors responsible for aberrant results. METHODS (13)C-UBT (UBiTkit; Otsuka Pharmaceutical,(More)
