BACKGROUND Eradication rates of standard triple therapy for Helicobacter pylori infections have decreased in recent years due to a worldwide increase in bacterial resistance. Sequential therapy has the advantage of a two-phase treatment regimen and achieves a superior result for H. pylori eradication in peptic ulcer disease. However, no study has yet(More)
BACKGROUND It is well accepted that in patients with uncomplicated peptic ulcers, Helicobacter pylori eradication therapy does not need to be followed by further antisecretory treatment. However, it is uncertain whether patients with bleeding peptic ulcers should receive maintenance antiulcer therapy after successful H pylori eradication and ulcer healing.(More)
OBJECTIVE Accuracy of diagnostic methods for detecting Helicobacter pylori (H. pylori) infection among patients with bleeding peptic ulcers has not been thoroughly investigated. The aim of this study was to compare the diagnostic tests and their combined usage in detection of H. pylori infection in patients with bleeding gastric ulcers and without the use(More)
Colorectal cancer (CRC) has become one of the most common fatal cancers. CRC tumorigenesis is a complex process involving multiple genetic changes to several sequential mutations or molecular alterations. P53 is one of the most significant genes; its mutations account for more than half of all CRC. Therefore, understanding the cellular genes that are(More)
BACKGROUND Gastroesophageal reflux disease (GERD) is a common gastrointestinal disease, yet there is no definitive gold standard to describe and diagnose it. AIM We used endoscopic examination and Carlsson's questionnaire to evaluate the prevalence of erosive esophagitis during health examinations of individuals in Taiwan. METHODS From October 2001 to(More)
BACKGROUND/AIMS A recent pilot study suggested that 18% of patients with hepatitis C viral infection achieved a sustained response to a 6-month course of 200 mg of oral amantadine alone with disappearance of serum hepatitis C virus ribonucleic acid. We prospectively studied 30 naive patients with chronic hepatitis C viral infection for the possible role of(More)
Negative CLO test pellets can be reused repeatedly in diagnostic endoscopy within a short period of time. However, the duration that these pellets can be stored at room temperature before second use remains unclear. A total of 360 patients, 190 males and 170 females, who required a CLO test during endoscopy, were enrolled in this study. Two biopsies were(More)
BACKGROUND Primary esophageal motility disorder, which can cause chest pain or dysphagia, is seldom reported in Chinese. With the introduction of an easy and less uncomfortable method to perform esophageal manometry by low-compliance perfusion system, we studied symptomatic patients for more than 10 years. These data were analyzed and were compared to(More)
