INTRODUCTION Non-traumatic biliary perforation other than the gallbladder is extremely rare and most commonly seen in children in association with congenital biliary anomalies. We present a rare case of choledocholithiasis that progressed to spontaneous perforation of the common hepatic duct probably from ischemic necrosis caused by impaction of large biliary stones. CASEREPORT A 62-year-old ...
To evaluate the role of chronic inflammation in the development of gallstones and biliary tract cancer, we examined the risk associated with 62 single nucleotide polymorphisms (SNPs), in 22 inflammation-related genes, in a population-based case-control study conducted in Shanghai, China, where the incidence of biliary tract cancer has been increasing in recent decades. The study included 411 ca...
Pigment gallstones, which are much less frequent than cholesterol stones, are classified descriptively as "black" or "brown". They are composed mostly of calcium hydrogen bilirubinate, Ca(HUCB)(2), which is polymerized and oxidized in "black" stones but remains unpolymerized in "brown" stones. Black stones form in sterile gallbladder bile but brown stones form secondary to stasis and anaerobic ...
Biliary infections are an important cause of morbidity in the Western world. With regard to epidemiology, etiology, microbiological spectrum, prevalence, location and composition of gallstones, pathogenesis, clinical sign and therapy, there are large differences between the spectrum of biliary infections in the East and in the West (Table 1). In Western countries, gallstones are found in 10 to ...
Biliary complications after orthotopic liver transplants are a continuing cause of morbidity and mortality. Biliary stones and sludge are less well known complications of hepatic transplantation, although they have long been recognized. Recently we experienced two cases of biliary stones developed after liver transplantation. One 32-year-old male, who frequently admitted due to recurrent cholan...
UNLABELLED Endoscopic Retrograde Cholangio-Pancreatography (ERCP) is accepted referred method of treatment of the choledocholithiasis. THE AIM OF THE STUDY Evaluation of efficacy and safety of the endoscopic treatment of the biliary tract stones. MATERIAL AND METHODS Results of 3309 Endoscopic Retrograde Cholangio-Pancreatography (ERCP) carried out in Division of Endoscopy of the General Su...
AIM To evaluate complications and management outcomes of retained long-term plastic biliary stents. METHODS Endoscopic plastic biliary stent placement was performed in 802 patients at Yeungnam University Hospital between January 2000 and December 2014. Follow-up loss with a subsequently forgotten stent for more than 12 mo occurred in 38 patients. We retrospectively examined the cause of bilia...
Abnormally low activity of hepatic bilirubin UDP-glucuronosyltransferase was found in 25% of 81 unselected patients with gallstones, as compared with only 3% in 35 controls. At the time of cholecystectomy, the stones were taken for analysis in 48 of 81 patients, and a bile sample was obtained in 42 of them. Among the stones, 75% were cholesterol stones, 15% pigment stones, and 10% 'intermediate...
BACKGROUND To determine the most common abnormal anatomical variations of extra-hepatic biliary tract (EHBT), and their relation to biliary tract injuries and stones formation. METHODS This is a retrospective review of 120 patients, who underwent endoscopic retrograde cholangiopancreaticography (ERCP) and/or magnetic resonance cholangiopancreaticography (MRCP), between July 2011 and June 2013...
