BACKGROUND AND AIM Few data describing short-term proton pump inhibitor (PPI) treatment in patients with globus sensation exist. The aim of this study was to evaluate the use of high-resolution manometry (HRM) for predicting the response to PPI treatment in patients with globus sensation. METHOD A total of 41 patients with globus sensation were treated(More)
BACKGROUND/AIM Periodic endoscopy for esophageal varices (EVs) and prophylactic treatment of high-risk EVs, i.e., medium/large EVs, small EVs with the red-color sign or decompensation, are recommended in cirrhotic patients. We assessed the cumulative risks for future EV bleeding using the following simple P2/MS index: (platelet count)2/[monocyte fraction(More)
Dear Editor: VIPomas are rare neuroendocrine tumors that secrete vasoactive intestinal polypeptide. They are detected in 1 in 10 million people per year. VIPomas commonly are detected within the pancreas, and the majority of extrapancreatic VIPomas are neurogenic tumors. Non-neurogenic extrapancreatic VIPomas are very rare. We are going to report a patient(More)
We investigated the apoptotic pathway during paraquat (PQ)-induced nephrotoxicity as well as renoprotective effects of chitosan oligosaccharide (COS) in male Sprague-Dawley rats because increasing evidences suggest that antioxidants may prevent PQ-induced apoptosis. Animals were pretreated with normal saline or COS (500 mg/kg, p.o.) 3 days before PQ (60(More)
The Dieulafoy lesion is a rare cause of severe gastrointestinal hemorrhage. Although it may occur anywhere in the gastrointestinal tract, the lesion is most commonly located in the stomach, and the small bowel is an extremely uncommon site. Since Dieulafoy lesion in the small bowel is difficult to access by endoscopy, it seems impossible to diagnose and(More)
Existing studies suggest that metformin lowers the risk and mortality of colorectal cancer. However, the effect of metformin on the suppression and prevention of colorectal adenomas is not clear. The aim of this study was to evaluate the effect of metformin on the recurrence of colorectal adenoma in diabetic patients with previous colorectal adenoma. Among(More)
