Prevalence of Extraesophageal Symptoms in Patients With Gastroesophageal Reflux Disease: A Multicenter Questionnaire-based Study in Korea.

Background/aims: Many patients with gastroesophageal reflux disease (GERD) also present with extraesophageal symptoms (EESs). This study sought to determine the prevalence of concomitant EESs and to evaluate quality of life (QOL) impairment in a Korean population with GERD.

Methods: This questionnaire-based study was carried out from 64 hospitals in Korea between October 2008 and March 2009.

Management of Asymptomatic Erosive Esophagitis: An E-Mail Survey of Physician's Opinions.

Background/aims: The management of asymptomatic erosive esophagitis is controversial. We surveyed physicians' opinions on asymptomatic erosive esophagitis using e-mail.

Methods: All members of the Korean Society of Neurogastro-enterology and Motility were invited to answer the questionnaire on the treatment and follow-up of patients with asymptomatic erosive esophagitis by e-mail.

Impact of previous gastric or colonic resection on polyethylene glycol bowel preparation for colonoscopy.

Introduction: Adequate bowel preparation is essential for successful completion of colonoscopy. This study examines whether previous bowel resection affects the quality of bowel preparation.

Methods: This study prospectively included patients who had gastric or colonic resection (bowel resection group, n = 92) and a control group (n = 92).

Risk of colorectal neoplasia in patients with solid organ transplantation.

The incidence of colorectal adenomas and advanced neoplasia in the transplant population has not been well characterized. The aim of this study was to determine whether or not there was an increased incidence of colorectal adenomas and advanced neoplasia in solid organ transplantation (SOT) recipients compared with an average-risk population. We reviewed 360 patients with solid organ transplants who underwent colonoscopy between February 1995 and July 2008, and 360 age- and gender-matched patients in an average-risk population.

Distinguishing xanthogranulomatous cholecystitis from the wall-thickening type of early-stage gallbladder cancer.

Background/aims: Xanthogranulomatous cholecystitis (XGC) mimics early-stage gallbladder (GB) cancer with wall thickening on computed tomography (CT), both clinically and radiologically. Preoperative differentiation of XGC from early-stage GB cancer is important for selecting the most appropriate surgical management. Therefore, we evaluated the clinical features and multidetector CT (MDCT) findings of XGC to determine whether it can be distinguished from early-stage GB cancer.

Prognostic relevance of pathologic subtypes and minimal invasion in intraductal papillary mucinous neoplasms of the pancreas.

Intraductal papillary mucinous neoplasms (IPMNs) of the pancreas are classified into the following four histopathologic subtypes: gastric, intestinal, pancreatobiliary, and oncocytic. However, the clinicopathologic characteristics of IPMN subtypes have not been fully clarified. Recently, a subgroup classification of minimally invasive intraductal papillary mucinous carcinomas (MI-IPMCs) was suggested in contrast to overt invasive carcinoma from IPMCs (IC-IPMCs).

Vaccination rate and seroepidemiology of hepatitis a in chronic-hepatitis-B-infected individuals in the korean army.

Background/aims: Vaccination against hepatitis A virus (HAV) is recommended for patients with chronic hepatitis B (CHB), since they are potentially at an increased risk of HAV-related morbidity and mortality. However, little is known about the adherence to these recommendations in the community. This study evaluated the current vaccination status and immunity against HAV among Korean military soldiers with CHB.

The speed of eating and functional dyspepsia in young women.

Background/aims: Little information is available on whether the speed of eating differs between individuals with and without dyspepsia, mainly because controlled studies are usually not feasible.

Methods: A survey was applied to 89 individuals with relatively controlled eating patterns, using questionnaires that assessed eating time and functional dyspepsia (FD) based on the Rome III criteria.

Results: The prevalence of FD was 12% (11 of 89 participants), and 7% (6 of 89) were diagnosed with gastroesophageal reflux disease (GERD).

Combination chemotherapy of oxaliplatin, 5-fluorouracil and low dose leucovorin in patients with advanced colorectal cancer.

Purpose: The aim of this study was to evaluate the efficacy and tolerability of the oxaliplatin, 5-fluorouracil (5-FU) and low dose leucovorin (LV) combination in patients with advanced colorectal cancer.

Materials And Methods: Patients with unresectable or recurrent colorectal carcinomas were prospectively accrued. Up to one prior chemotherapy regimen was allowed.
