Morphological advantages of endoscopic treatment in obstructive chronic pancreatitis.

Background: and study aims: Chronic pancreatitis is associated with recurrent or persistent abdominal pain over the course of the disease. Ductal hypertension showing obstructed and dilated pancreatic duct has been suggested as a major factor in the mechanism of pain in chronic pancreatitis. Many studies investigating pain relief after endoscopic treatment of pancreatic duct (PD) are available, but the number of studies regarding the morphological changes to pancreas such as changes in PD caliber, pancreatic parenchyma, and especially pancreatic volume is far fewer.

Local Recurrence and Its Risk Factor after Incomplete Resection of Colorectal Advanced Adenomas: A Single Center, Retrospective Study.

Background/aims: Colonoscopy can detect precancerous lesions, which can subsequently be removed and reduce incidences of and mortality from colorectal cancer (CRC). However, recently published data have highlighted a significant rate of CRC in patients who previously underwent colonoscopy. Among many reasons, incomplete resection has been considered as a significant contributor.

Risk Factors Associated with Rebleeding in Patients with High Risk Peptic Ulcer Bleeding: Focusing on the Role of Second Look Endoscopy.

Background: Re-bleeding after initial hemostasis in peptic ulcer bleeding can be life threatening. Identification of factors associated with re-bleeding is important. The aims of this study were to determine incidence of rebleeding in patients with high risk peptic ulcer bleeding and to evaluate factors associated with rebleeding.

Esophageal cancer treated by endoscopic submucosal dissection after neoadjuvant chemoradiotherapy: a case report.

Introduction: The treatment of esophageal cancer remains clinically challenging because of the overall poor prognosis associated with the disease. The mortality rate associated with surgical treatment is high, and the majority of diagnosed patients are old. As such, surgery is not possible in many cases, even when the cancer has progressed to a resectable state.

Non-curative endoscopic resection does not always lead to grave outcomes in submucosal invasive early gastric cancer.

Background: Endoscopic submucosal dissection (ESD) has been widely performed for the treatment of early gastric cancer (EGC). The aim of this study is to examine the effectiveness of ESD in submucosal invasive gastric cancers (SM-GC), with a special focus on patients who underwent non-curative resection.

Methods: Data for 1,246 patients who underwent ESD for treatment of EGC at six medical centers in Daegu-Gyeongbuk, Korea, between February 2003 and May 2010 were collected.

Clinical outcomes of the endoscopic submucosal dissection of early gastric cancer are comparable between absolute and new expanded criteria.

Background/aims: Advances in endoscopic submucosal dissection (ESD) techniques have led to the development of expanded criteria for endoscopic resection of early gas-tric cancer (EGC). The aim of this study was to evaluate the short- and long-term outcomes for ESD using indication cri-teria.

Methods: A total of 1,105 patients underwent ESD for EGC at six medical centers.

Predictive risk factors of perforation in gastric endoscopic submucosal dissection for early gastric cancer: a large, multicenter study.

Background: Although endoscopic submucosal dissection (ESD) is standard therapy for early gastric cancer, the complication rate is unsatisfactory, with perforation as the major complication during ESD. There have been several reports regarding the complications of ESD for gastric tumor especially perforation; however, little is known about the predictors for complications in patients undergoing ESD. The purpose of this retrospective study was to determine the risk factors for perforation in patients with early gastric cancer during ESD.

Prevalence of common skin diseases and their associated factors among military personnel in Korea: a cross-sectional study.

This study was conducted to clarify the prevalence of common skin diseases and their associated factors among military personnel in Korea. Four dermatologists visited adjacent military units and examined soldiers. A structured questionnaire that included questions about known skin diseases, demographic information, and questions for the Perceived Stress Index was completed for each participant.

Biliary cast formation with sclerosing cholangitis in critically ill patient: case report and literature review.

Sclerosing cholangitis in critically ill patients (SC-CIP) is a rare condition that is not familiar to many radiologists. In addition, the associated imaging findings have not been described in the radiological literature. We report a case of biliary cast formation with SC-CIP and describe the radiological findings of CT, magnetic resonance cholangiopancreatography (MRCP), and endoscopic retrograde cholangiography (ERC).

[Clinical characteristics of gastroesophageal reflux disease with esophageal injury in korean: focusing on risk factors].

Background/aims: Recent studies suggest that the prevalence of gastroesophageal reflux disease (GERD) is increasing in Korea. However, studies on risk factors for GERD have yielded inconsistent results. The aims of this study were to compare clinical features between symptomatic syndromes without esophageal injury (=non-erosive disease [NED]) and syndromes with esophageal injury (=erosive disease [ED]), and to determine risk factors associated ED.

Clinical outcomes for perforations during endoscopic submucosal dissection in patients with gastric lesions.

Background: The endoscopic submucosal dissection (ESD) technique has been gaining popularity, with continued advances in this treatment approach. However, ESD still is associated with potential complications such as severe bleeding and perforation.

Methods: This study was performed to compare the clinical outcomes for macro- and microperforations with ESD procedures and to determine the short-term prognosis after ESD.

[A case of gastric glomus tumor].

Glomus tumor is a tumor arising from glomus body, a nodular form of arteriolovenular anastomosis that functions to regulate blood flow according to temperature. Gastrointestinal glomus tumors are rare and most frequently occur in the stomach as a subepithelial tumor. A 46-year-old woman presented with an incidental finding of a subepithelial tumor in the stomach.

[Cyclooxygenase-2 expression according to size and location of gastric and colorectal tubular adenomas].

Background/aims: Recent studies have shown that cyclooxygenase-2 (COX-2) may be involved in the process of invasion, growth and apoptosis in colorectal carcinoma and in the growth and tumorigenesis in familial adenomatous polyposis. This study was conducted to determine the significance of the expression of COX-2 in gastric and colorectal adenomas.

Methods: Forty-nine samples of gastric adenoma and fifty-seven samples of colorectal adenoma were obtained by endoscopic mucosal resection or polypectomy from 106 patients from January 2000 to July 2003.

[The diagnostic validity of Helicobacter pylori stool antigen test in the pre- and post-eradication].

Background/aims: The efficacy of a new enzyme immunoassay designed to detect H. pylori antigens in stool (HpSA) was evaluated before and after the eradication therapy.

Methods: HpSA test was performed in 75 patients whose H.

[A case of toxic hepatitis induced by habitual glue sniffing].

The link between toxic hepatitis and exposure to organic solvents is relatively well-documented, but there are no specific laboratory or histologic findings diagnostic of chemical-induced hepatitis. Clinical history, therefore, is very important in making a diagnosis. A history of glue sniffing is sometimes overlooked and glue sniffing has not received much attention as a cause of hepatitis.

[Diagnosis of Helicobacter pylori infection with urine and stool].

Background/aims: The urine antibody and stool antigen test are newly developed non-invasive tests for Helicobacter pylori (H. pylori) infection. The aim of this study was to assess the diagnostic value of these tests.

[Assessment of quality of life and associated factors in patients with chronic viral liver disease].

Background/aims: The aim of this study was to measure health related quality of life (HRQOL) in patients with chronic viral hepatitis or cirrhosis and to determine factors associated with more severe impairment.

Methods: We conducted a cross-sectional study in which we documented patients' demographic and clinical characteristics and measured their HRQOL using the Korean version of Short Form-36. A total of 375 patients were enrolled in the study.
