Endoscopic treatment of biliary strictures involving plastic stent placement has been used widely. The use of self-expandable metal stents (SEMSs) has been described for anastomotic strictures following liver transplantation (LT). This review aimed to assess and compare the efficacy of plastic stents with SEMS in LT patients. Information was retrieved regarding technical success, stricture resolution, the number of endoscopic retrograde cholangiography procedures, follow-up, immediate, and late complications...

Postoperative biliary strictures are usually complications of cholecystectomy. Endoscopic plastic stent prosthesis is generally undertaken for treating benign biliary strictures. Recently, fully covered metal stents have been shown to be effective for treating benign distal biliary strictures. We present the case of a 53-year-old woman with liver injury in which imaging studies showed a common hepatic duct stricture. Endoscopic retrograde cholangiopancreatography also confirmed the presence of a common hepatic duct stricture...

Portal biliopathy refers to cholangiographic abnormalities which occur in patients with portal cavernoma. These changes occur as a result of pressure on bile ducts from bridging tortuous paracholedochal, epicholedochal and cholecystic veins. Bile duct ischemia may occur due prolonged venous pressure effect or result from insufficient blood supply. In addition, encasement of ducts may occur due fibrotic cavernoma. Majority of patients are asymptomatic. Portal biliopathy is a progressive disease and patients who have long standing disease and more severe bile duct abnormalities present with recurrent episodes of biliary pain, cholangitis and cholestasis...

Absence of portal vein bifurcation is a rare anomaly. We report a patient with this anomaly who underwent right hemihepatectomy for treatment of hepatocellular carcinoma. Although the procedure was carefully performed with a preoperative three-dimensional simulation and intraoperative cholangiography, postoperative portal vein thrombosis occurred. J. Med. Invest. 63: 315-318, August, 2016.

BACKGROUND: The most common adverse event of endoscopic retrograde cholangiopancreatography is pancreatitis. Precut sphincterotomy has been regarded as a risk factor. Some authors have stated that early precut may actually reduce post-ERCP pancreatitis risk. However, early precut as a preventive measure has not been compared to other preventive measures, such as pancreatic duct stent placement. AIM: To compare the efficacy of early precut sphincterotomy versus pancreatic duct stent placement in high-risk subjects undergoing endoscopic retrograde cholangiopancreatography for the prevention of post-endoscopic cholangiopancreatography...

PURPOSE: To compare the length of the right hepatic duct (RHD) measured on rotatory coronal 2D MR cholangiography (MRC), rotatory axial 2D MRC, and reconstructed 3D MRC. MATERIALS AND METHODS: Sixty-seven donors underwent coronal and axial 2D projection MRC and 3D MRC. RHD length was measured and categorized as ultrashort (≤1 mm), short (>1-14 mm), and long (>14 mm). The measured length, frequency of overestimation, and the degree of underestimation between two 2D MRC sets were compared to 3D MRC...

INTRODUCTION: Misidentification of the extrahepatic bile duct anatomy during laparoscopic cholecystectomy (LC) is the main cause of bile duct injury. Easier intraoperative recognition of the biliary anatomy may be accomplished by using near-infrared fluorescence (NIRF) imaging after an intravenous injection of indocyanine green (ICG). Promising results were reported for successful intraoperative identification of the extrahepatic bile ducts compared to conventional laparoscopic imaging...

BACKGROUND AND AIMS: Magnetic compression anastomosis is a rescue technique for recanalization of complete biliary strictures. Here, we present magnetic compression anastomosis with novel through-the-scope magnets in patients with complete duct-to-duct anastomosis obstruction after liver transplantation. METHODS: The magnets were 2 and 2.4 mm in diameter, with a hole at the center for inserting a guidewire. One of the magnets was advanced through the scope up to the distal site of the stricture by using a 7F pusher...

Limy bile syndrome extending to the common bile duct (CBD) is a rare condition that lacks a standardized treatment. Laparoscopic cholecystectomy with laparoscopic choledocholithotomy by CBD exploration is preferred because it preserves the function of the sphincter of the Vater's papilla and allows treatment of both lesions. A 37-year-old man who was receiving entecavir for chronic hepatitis B developed right upper quadrant pain. Abdominal ultrasonography revealed a calcified shadow in the gallbladder and CBD...

BACKGROUND: Roux-en-Y reconstructive surgery excludes the biliopancreatic system from conventional endoscopic access. Balloon-assisted enteroscopy allows therapeutic endoscopic retrograde cholangiopancreatography (ERCP) in these patients, avoiding rescue surgery. The objective of the current study is to compare success and complication rate of double-balloon (DBE) and single-balloon enteroscope (SBE) to perform ERCP in Roux-en-Y patients. METHODS: Seventy three Roux-en-Y patients with suspected biliary tract pathology underwent balloon-assisted enteroscopy in a tertiary-care center...
