Previous observations suggest that glucagon-like peptide-1 (GLP-1) is released into the bloodstream only when dietary carbohydrate enters the duodenum at rates that exceed the absorptive capacity of the proximal small intestine to contact GLP-1 bearing mucosa in more distal bowel. The aims of this study were to determine the effects of modifying the length(More)
BACKGROUND Mixed alcoholic drinks are increasingly being consumed in "diet" varieties, which could potentially empty more rapidly from the stomach and thereby increase the rate of alcohol absorption when compared with "regular" versions containing sugar. METHODS We studied 8 healthy males twice in randomized order. On each day, they consumed an(More)

Regarding liver involvement, it was uncommon to be reported in previous medical literature from Western countries. This study observes the relationship between scrub typhus and liver function. From January 1998 to August 2003 in Kaohsiung Chang(More)
BACKGROUND Few studies have focused on the effect of dietary residue on preparation for colonoscopy. OBJECTIVE To determine the impact of a low-residue diet on the quality of bowel preparation. SETTING Chang Gung Memorial Hospital, Kaohsiung Medical Center, Taiwan. PATIENTS Eight hundred four consecutive patients (50.4 ± 11.6 y (range, 18-88 y), 43.6%(More)
INTRODUCTION Cells containing GIP and CCK predominate in the upper small intestine, while those containing GLP-1 are located more distally. Our aim was to compare the hormonal, glycemic and appetite responses to different sites of glucose delivery. METHODS Ten healthy males were each studied twice, in randomized order. A catheter was positioned with(More)
Pneumatic dilation (PD) is considered to be the first line nonsurgical therapy for achalasia. The principle of the procedure is to weaken the lower esophageal sphincter by tearing its muscle fibers by generating radial force. The endoscope-guided procedure is done without fluoroscopic control. Clinicians usually use a low-compliance balloon such as Rigiflex(More)
Severe caustic injury to the gastrointestinal tract carries a high risk of luminal strictures. The aim of this retrospective study was to identify predicting factors for progress of caustic injury to gastric outlet obstruction (GOO) and esophageal strictures (ES), using modified endoscopic mucosal injury grading scale. We retrospectively reviewed medical(More)
A 26-year-old man had suffered from several episodes of right upper-quadrant pain for 6 months. Abdominal ultrasonography showed multiple saccular dilatations of the intrahepatic biliary tract, with hepatolithiasis at the bilateral hepatic lobe. Abdominal computed tomography also revealed saccularly dilated intrahepatic ducts with hepatolithiasis.(More)
BACKGROUND Foreign object ingestion and food bolus impaction are a common clinical problem. We report our clinical experiences in endoscopic management for adults, foreign body ingestion, and food bolus impaction. METHOD A retrospective chart review study was conducted on adult patients with foreign body ingestion and food bolus impaction between January(More)
