Endoscopic retrograde cholangiopancreatography (ERCP) is a very useful investigation in the study of RPC. The location of stones and strictures and the morphology of the bile ducts are well delineated. Moreover, cholangitis liver abscesses and biliary-enteric fistulas, which are frequently encountered in RPC, are demonstrated. ERCP can also be used to differentiate RPC from ascariasis, clonorchiasis, hepatocellular carcinoma and cholangiocarcinoma, which sometimes have quite similar clinical pictures and can be confused with RPC. ERCP should be performed in every patient with RPC in order to plan surgical treatment. Endoscopic papillotomy (EPT) is indicated in RPC patients with residual common bile duct stones or papillary stenosis, and as primary treatment in selected high-risk patients. More studies are necessary to establish additional indications for EPT.</p>","PeriodicalId":75717,"journal":{"name":"Clinics in gastroenterology","volume":"15 2","pages":"393-415"},"PeriodicalIF":0.0,"publicationDate":"1986-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"14849855","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}

Owing to its crucial location at the confluence of the bile and pancreatic ducts, many of these clinical disorders lead to an impedance to the flow of secretions from the liver and pancreas. Thus, most symptomatic papillary disorders present with a rather predictable and monotonous conglomeration of symptoms. The common clinical presentations of papillary disorders include abdominal pain, jaundice, fever, pruritus and pancreatitis. Rarely, gastrointestinal bleeding leading to anaemia and weight loss may also be observed.</p><p>The advent of ERCP rekindled interest in diseases of the papilla. The major duodenal papilla is more accessible now than ever before. The endoscopist can visualize the papilla within minutes and take an appropriate tissue sample using different biopsy techniques. Definitive diagnosis is thus possible in most patients with papillary tumours. Along with ERCP, the miniaturization of a perfusion system with minimal compliance enabled us to accurately evaluate sphincter of Oddi (SO) dynamics. This in turn gave us a wealth of information on the physiology of the sphincter of Oddi. In addition, ERCP manometry led to a resurgence of interest in SO dysfunction, especially papillary stenosis. Several characteristic manometric abnormalities have been identified recently. Finally, the introduction of endoscopic sphincterotomy (ES), nearly a decade ago, opened a new chapter in the therapeutic approach towards papillary disorders. While the technique was initially applied in the management of common bile duct stones in postcholecystectomy patients who were high operative risks, the indications for ES steadily increased during the past decade. Experience over the years led us to be convinced that ES is equally effective in the management of a variety of papillary disorders, including choledochoduodenal fistula, choledochocele, papillary tumours and SO dysfunction. Most recently, other ancillary procedures such as endoprosthesis insertion have emerged as yet another useful therapeutic modality. Such internal biliary stents have been shown to be suitable in establishing biliary drainage in ampullary neoplasms when the operative approach is considered risky.</p></div>","PeriodicalId":75717,"journal":{"name":"Clinics in gastroenterology","volume":"15 2","pages":"Pages 439-456"},"PeriodicalIF":0.0,"publicationDate":"1986-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"137439714","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}
