Tumors of the gastric cardia are among the most technically difficult lesions to remove by endoscopic submucosal dissection (ESD). This study aimed to evaluate the therapeutic outcomes of ESD in gastric cardia tumors according to clinicopathologic characteristics, and to assess the predictive factors for incomplete resection.We conducted a retrospective(More)
A Dieulafoy's lesion is a vascular abnormality consisting of a large caliber-persistent tortuous submucosal artery. A small mucosal defect with the eruption of this protruding vessel can cause bleeding. In fact, a Dieulafoy's lesion is a relatively rare but potentially life-threatening condition. It accounts for 1% to 2% of cases of acute gastrointestinal(More)
BACKGROUND A high incidence of venous thromboembolism (VTE) has been observed in patients with cancer. However, few data are available on patients with cholangiocarcinoma. OBJECTIVES The aim of this study was to evaluate the clinical characteristics and risk factors of VTE and to investigate whether VTE would affect the survival of patients with(More)
BACKGROUND Endoscopic ultrasonography (EUS) is a valuable imaging tool for evaluating subepithelial lesions in the stomach. However, there are few studies on differentiation between gastrointestinal stromal tumors (GISTs) and benign mesenchymal tumors, such as leiomyoma or schwannoma, with the use of EUS. In addition, there are limitations in the analysis(More)
BACKGROUND/AIMS Recent studies have reported the potentials of endoscopic papillary large balloon dilatation (EPLBD) with minor endoscopic sphincterotomy (EST) for the complete removal of common bile duct (CBD) stone in the high risk groups. However, there have been no reports about the recurrence of the CBD stone after EPLBD with minor EST. The aim of this(More)
BACKGROUND/AIMS Globus is a persistent or intermittent non-painful sensation of a lump or foreign body in the throat. Given the benign nature of the condition and the association of gastroesophageal reflux disease, empirical therapy with proton pump inhibitor seems reasonable for patients with typical globus. The aim of this study was to investigate the(More)
AIM To identify the clinicopathological predictors of lymph node (LN) metastasis and evaluate the outcomes of endoscopic submucosal dissection (ESD) in papillary adenocarcinoma-type early gastric cancers (EGCs). METHODS From January 2005 to May 2013, 49 patients who underwent surgical operation and 24 patients who underwent ESD for papillary(More)
OBJECTIVE The renin-angiotensin system (RAS) influences cardiovascular homeostasis, and Angiotensin II type 1 receptor (AGTR1) is the main effector of RAS, and AGTR2 antagonizes AGTR1. Accumulating evidence supports the role of RAS in the paracrine regulation of tumorigenesis in several cancer types. Although treatment with AGTR1 antagonist (losartan) or(More)
BACKGROUND/AIMS Helicobacter pylori eradication therapy has been used as a first-line treatment for H. pylori-positive gastric mucosa-associated lymphoid tissue (MALT) lymphoma. However, the management strategy for H. pylori-negative MALT lymphoma remains controversial. Therefore, the aim of this study was to examine the success rate of each treatment(More)
BACKGROUND Gastric epithelial dysplasia (GED) can be morphologically categorized into adenomatous and foveolar types. To date, there have been few studies on the clinical characteristics of GEDs according to the morphologic types. Therefore, we here aimed to elucidate the clinicopathologic characteristics of patients with GED and the long-term follow-up(More)
