Investigation of the excluded stomach after Roux-en-Y gastric bypass: The role of percutaneous endoscopy.
Accessing the bypassed portion of the stomach via conventional endoscopy is difficult following Roux-en-Y gastric bypass surgery. However, endoscopic examination of the stomach and small bowel is possible through percutaneous access into the bypassed stomach (BS) with a combined […]
Comparison of esomeprazole enteric-coated capsules vs esomeprazole magnesium in the treatment of active duodenal ulcer: A randomized, double-blind, controlled study.
AIM: To evaluate the efficacy and tolerability of two different preparations of esomeprazole in healing duodenal ulcers. METHODS: A total of 60 patients with active duodenal ulcers were enrolled and randomized to receive esomeprazole enteric-coated […]
Double-balloon enteroscopy reliably directs surgical intervention for patients with small intestinal bleeding.
AIM: To evaluate preoperative double-balloon enteroscopy for determining bleeding lesions of small intestine, thus directing selective surgical intervention. METHODS: We retrospectively reviewed 56 patients who underwent double-balloon enteroscopy to localize intestinal bleeding prior to surgical intervention, and compared enteroscopic findings with […]
Prognostic significance of S100A4 and vascular endothelial growth factor expression in pancreatic cancer.
AIM: To investigate the expression of vascular endothelial growth factor (VEGF) and calcium-binding protein S100A4 in pancreatic cancer and their relationship to the clinicopathological parameters and prognosis of pancreatic cancer. METHODS: Expression status of VEGF and S100A4 was examined in […]
Comparative analysis of common CFTR polymorphisms poly-T, TG-repeats and M470V in a healthy Chinese population.
AIM: To investigate the three important cystic fibrosis transmembrane conductance regulator (CFTR) haplotypes poly-T, TG-repeats and the M470V polymorphisms in the Chinese population, and to compare their distribution with that in Caucasians and other Asian populations. METHODS: Genomic […]
Changes of ghrelin following oral glucose tolerance test in obese children with insulin resistance.
AIM: To characterize changes in ghrelin levels in response to oral glucose tolerance test (OGTT) and to correlate changes in ghrelin levels with changes in insulin and glucose following OGTT in Chinese obese children of Tanner I and II […]
Effect of H pylori infection and its eradication on hyperammo-nemia and hepatic encephalopathy in cirrhotic patients.
AIM: To investigate the relationship between H pylori infection, blood ammonia concentration and hepatic encephalopathy (HE), and the effect of H pylori eradication in cirrhotic patients. METHODS: From July 2003 to January 2005, 457 cirrhotic patients in […]
Hemodynamic effects of propranolol with spironolactone in patients with variceal bleeds: A randomized controlled trial.
AIM: To study the hemodynamic effects of spironolactone with propranolol vs propranolol alone in the secondary prophylaxis of variceal bleeding. METHODS: Thirty-five cirrhotics with variceal bleeding randomly received propranolol (n = 17: Group A) or spironolactone plus propranolol […]
Importance of the surrounding colonic mucosa in distinguishing between hyperplastic and adenomatous polyps during acetic acid chromoendoscopy.
AIM: To examine the characteristics of colonic polyps, where it is difficult to distinguish adenomatous polyps from hyperplastic polyps, with the aid of acetic acid chromoendoscopy. METHODS: Acetic acid spray was applied to colonic polyps smaller […]
Portal hemodynamics as predictors of high risk esophageal varices in cirrhotic patients.
AIM: To evaluate portal hypertension parameters in liver cirrhosis patients with and without esophageal varices (EV). METHODS: A cohort of patients with biopsy confirmed liver cirrhosis was investigated endoscopically and with color Doppler ultrasonography as a possible non-invasive predictive tool. The […]
