Gallstone prevalence and risk factors in patients with ulcerative colitis in Korean population.

This study aims to evaluate the prevalence, risk factors, and relative risk of gallstones and associated disease in patients with ulcerative colitis (UC). Medical records of 311 patients diagnosed with UC between January 2004 and February 2015 were reviewed retrospectively. To assess relative risk, 622 patients matched by age, sex, and body mass index were included as a control group.

Complications and management of forgotten long-term biliary stents.

Aim: To evaluate complications and management outcomes of retained long-term plastic biliary stents.

Methods: Endoscopic plastic biliary stent placement was performed in 802 patients at Yeungnam University Hospital between January 2000 and December 2014. Follow-up loss with a subsequently forgotten stent for more than 12 mo occurred in 38 patients.

Association between status and metachronous gastric cancer after endoscopic resection.

Aim: To investigate the effect of () status test and eradication on the occurrence of metachronous gastric cancer (MGC) after endoscopic submucosal dissection (ESD) of early gastric cancer (EGC) and risk factors of MGC.

Methods: The authors retrospectively reviewed the medical records of 433 patients (441 lesions) who underwent ESD for EGC from January 2005 to January 2015 in Yeungnam University Hospital. Patients were categorized into two groups; the tested group ( = 257) and the non-tested group ( = 176) based on performance of status test after ESD of EGC.

Therapeutic outcomes of endoscopic submucosal dissection for early gastric cancer: single-center study.

Objectives: Endoscopic submucosal dissection (ESD) has been widely accepted for selected patients with early gastric cancer (EGC). The aim of this study was to assess the therapeutic outcomes after ESD according to the pathological extent.

Patients And Methods: From January 2005 to December 2014, a total of 599 patients with 611 lesions were enrolled in this study.

Predictors of Mortality in Korean Patients with Pyogenic Liver Abscess: A Single Center, Retrospective Study.

Background/aims: The mortality rate of pyogenic liver abscess (PLA) has decreased dramatically, but it remains a potentially life threatening disease. Most cases are cryptogenic or occur in elderly men with underlying biliary tract disease. Although several studies have addressed the characteristics and etiology of PLA, research on factors affecting PLA-associated mortality is lacking.

A case of spine origin chondroblastoma metastasis to lung.

Chondroblastoma is a rare benign cartilaginous neoplasm that accounts for approximately 1% of all bone tumors and characteristically arises in the epiphysis of a long bone, particularly the humerus, tibia, and femur. Chondroblastoma can affect people of all ages. It is, however, most common in children and young adults between the ages of 10 and 20 years.
