In the past year, several studies have been carried out on the association between Helicobacter pylori infection and a miscellany of extradigestive diseases, such as cardiovascular, immunological, and various other pathologies. In particular, a higher prevalence of H pylori infection in patients affected by ischaemic heart disease has been described and there is growing evidence for an associat...

BACKGROUND AND AIMS endoscopic ultrasound (EUS) is a very sensitive and specific technique for the diagnosis of biliary diseases. This procedure has proven its usefulness in cases of high suspicion of biliary disease (history of gallstones and dilatation of the intrahepatic and/or extrahepatic bile ducts). We know less about its usefulness in cases of low suspicion of biliary pathology.The aim ...

BACKGROUND The ras gene family (H-ras, N-ras and K-ras) are oncogenes that mutate frequently in human cancer, specially in tumors of the biliary tract and pancreas. AIM To determine the frequency of K-ras gene codon 12 mutation in pancreatic and biliary tumors. MATERIAL AND METHODS Samples of 35 gallbladder, 15 ampulla of Vater, 10 biliary tract and 9 pancreatic tumors, were analyzed. The t...

OBJECTIVES To summarize the pathotyping and clinical manifestations of biliary cast syndrome in patients after an orthotopic liver transplant. MATERIALS AND METHODS The clinical manifestations, auxiliary examination, therapeutic regimen, and clinical efficacy of 103 biliary cast syndrome patients who underwent an orthotopic liver transplant were retrospectively analyzed. Patients were divided...

Most biliary stone diseases need to be treated surgically. However, in special cases that traditional biliary tract endoscopic access is not allowed, a multidisciplinary approach using hybrid technique with urologic instrumental constitute a treatment option. We report a case of a patient with complex intrahepatic stones who previously underwent unsuccessful conventional approaches, and who sym...

INTRODUCTION The spontaneous perforation of the biliary tract (SPBT) is an extremely rare cause of peritonitis, which was first described by Freeland in 1982, to date only around 70 cases have been reported. Here we present a case of spontaneous perforation of the biliary tract, in a patient with choledocholithiasis, which was treated with ultrasound-guided drainage and ERCP. CASE REPORT A 51...

gallbladder and biliary tree is low compared with the many parenchymal hepatic conditions that occur in animals. Diseases of the extrahepatic biliary system are often confused with other intraabdominal disorders because their course and clinical signs are similar. Diseases that require surgery of the extrahepatic biliary system in dogs are primarily acquired and include extrahepatic biliary tra...

Intestinal perforation from a migrated biliary stent is a known complication of endoscopic biliary stent placement. We present a case of stent migration and resultant duodenal perforation after stent placement for a malignant biliary stricture in a 52-year-old woman. We review the current literature on the diagnosis and management of stent migration and intestinal perforation after endoscopic s...
