Endoscopic approach to acute pancreatitis. 内镜入路治疗急性胰腺炎。

Endoscopic retrograde cholangiopancreatography (ERCP) has been used primarily to evaluate and treat disorders of the biliary tree. Recently, endoscopic techniques have been adapted for pancreatic sphincterotomy, stenting, stricture dilation, treatment of duct leaks, drainage of fluid collections, and stone extraction via the major and minor papillae. In patients with acute and recurrent pancreatitis, ERCP carries a higher than average risk of post-ERCP pancreatitis. This risk can be reduced with the placement of a prophylactic pancreatic stent. Magnetic resonance cholangiopancreatography (MRCP) can establish the anatomy of the biliary and pancreatic ducts, identify pancreas divisum or pancreatic ductal strictures, depict bile duct stones, and demonstrate pancreatic or biliary duct dilation. Endoscopic ultrasound (EUS) provides a safer, less invasive, and often more sensitive measure for evaluating the pancreas and biliary tree, and allows some options for therapy. In acute and recurrent pancreatitis, EUS and MRCP can be used to establish a diagnosis; ERCP can be reserved for therapy.</p>","PeriodicalId":21173,"journal":{"name":"Reviews in gastroenterological disorders","volume":"6 3","pages":"119-35"},"PeriodicalIF":0.0,"publicationDate":"2006-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"26299020","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The PPIs that have IV formulations in the United States (esomeprazole, lansoprazole, and pantoprazole) are approved for different indications; the key differences among them relate to their ability to reach specific gastric pH, time to maintain a specific gastric pH, and ease of use of the IV formulation (eg, reconstitution, requirement of inline filters, infusion times).</p>","PeriodicalId":21173,"journal":{"name":"Reviews in gastroenterological disorders","volume":"6 1","pages":"22-34"},"PeriodicalIF":0.0,"publicationDate":"2006-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"25892183","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, this definition now seems outdated, because structural and molecular abnormalities have begun to be recognized in subsets of patients with the irritable bowel syndrome (IBS), the prototypic functional bowel disease. A complex classification system based arbitrarily on symptom criteria does not fit in with a number of emerging facts. For example, the symptom overlap of IBS with gastroesophageal reflux disease is not due to chance, and the emergence of post-infectious IBS, dyspepsia, or both after Salmonella gastroenteritis fits better with a 1-disease model. A new paradigm seems to be needed. All of these disorders may arise after infection or gut inflammation, but the phenotype depends on localized neuromuscular dysfunction in the predisposed human host (the \"irritable gut\").</p>","PeriodicalId":21173,"journal":{"name":"Reviews in gastroenterological disorders","volume":"6 2","pages":"72-8"},"PeriodicalIF":0.0,"publicationDate":"2006-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"26022599","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Chromoendoscopy and its alternatives for colonoscopy: useful in the United States? 色内窥镜及其结肠镜检查的替代品:在美国有用吗?

{"title":"Chromoendoscopy and its alternatives for colonoscopy: useful in the United States?","authors":"Claire Helbig","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>American endoscopists have essentially ignored chromoendoscopy (dye spraying) in the colon and overwhelmingly perform white-light colonoscopy only. The published studies suggest that routine use of chromoendoscopy in Western populations will lead to identification of additional flat lesions. However, a number of these studies have design flaws. The authors' interpretation of the existing data is that pancolonic chromoendoscopy to detect flat and depressed lesions is not yet proven as a useful and therefore necessary adjunct to routine colonoscopic examination in non-inflammatory bowel disease patients in the United States. Chromoendoscopy, particularly combined with magnification, is very effective in delineating the pit pattern of polyps and in allowing real-time differentiation of adenomatous from non-adenomatous lesions. There might be a role for chromo endoscopy with high magnification in the delineation of unresected portions of lateral spreading tumors being removed by piecemeal polypectomy and in the evaluation of polypectomy scars during endoscopic follow-up. The authors suggest that US endoscopists begin to familiarize themselves with shape classification, and that they learn a method to determine histology in real time.</p>","PeriodicalId":21173,"journal":{"name":"Reviews in gastroenterological disorders","volume":"6 4","pages":"209-20"},"PeriodicalIF":0.0,"publicationDate":"2006-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"26490393","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
