Global DNA hypomethylation is an early molecular event in Hp-related gastric carcinogenesis. Further studies with more cases and a longer follow-up are needed to establish the potential GC predictive role of DNA hypomethylation.
Short-term administration of gabexate or somatostatin in patients at high risk for pancreatitis is ineffective for prevention of ERCP-induced pancreatitis. Pancreatic injury is related to maneuvers used to obtain biliary access rather than to any patient characteristic or endoscopist experience.
We report a case of gastric lipoma which manifested with an episode of acute gastrointestinal hemorrhage. Preoperative diagnosis was based on the US, CT, and MRI findings, as the results of gastrointestinal endoscopy were inconclusive. The role of current imaging methods, and particularly of MRI, is discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
