Biliary strictures constitute 40% to 60% of the biliary complications after liver transplantation. They are more common after living donor related liver transplantation (LDLT) than orthotopic liver transplantation (OLT). Balloon dilation followed by multiple plastic stent insertion leads to a mean resolution rate of 84% in the treatment of ASs after OLT. Endoscopic treatment of ASs after LDLT is more difficult because of the small size of the ASs, their multiple number and peripheral location. Balloon dilation followed by multiple plastic stent insertion had a mean resolution rate of 53%...

The Tokyo Guidelines 2013 (TG13) recommend that endoscopic drainage should be the first-choice treatment for biliary decompression in patients with acute cholangitis. Timing of biliary drainage for acute cholangitis should be based on the severity of the disease. For patients with severe acute cholangitis, appropriate organ support and urgent biliary drainage are needed. For patients with moderate acute cholangitis, early biliary drainage is needed. For patients with mild acute cholangitis, biliary drainage is needed when initial treatment such as antimicrobial therapy is ineffective...

BACKGROUND: Treatment of unresectable malignant hilar biliary stricture (UMHBS) is challenging, especially after failure of repeated transpapillary endoscopic stenting. Endoscopic ultrasonography-guided intrahepatic biliary drainage (EUS-IBD) is a recent technique for intrahepatic biliary decompression, but indications for its use for complex hilar strictures have not been well studied. The aim of this study was to assess the feasibility and safety of EUS-IBD for UMHBS after failed transpapillary re-intervention...

Biliary complications are the most common post-liver transplant (LT) complications with an incidence of 15%-45%. Furthermore, such complications are reported more frequently in patients who undergo a living-donor LT (LDLT) compared to a deceased-donor LT (DDLT). Most post-LT biliary complications involve biliary strictures, bile leakage, and biliary stones, although many rarer events, such as hemobilia and foreign bodies, contribute to a long list of related conditions. Endoscopic treatment of post-LT biliary complications has evolved rapidly, with new and effective tools improving both outcomes and success rates; in fact, the latter now consistently reach up to 80%...

The failure rate of endoscopic retrograde cholangiopancreatography for biliary cannulation is approximately 6%-7% in cases of obstructive jaundice. Percutaneous transhepatic biliary drainage (PTBD) is the procedure of choice in such cases. Endoscopic ultrasound-guided biliary drainage (EGBD) is a novel technique that allows biliary drainage by echoendoscopy and fluoroscopy using a stent from the biliary tree to the gastrointestinal tract. Information in PubMed, Scopus, clinicaltrials.gov and Cochrane review were analyzed to obtain studies comparing EGBD and PTBD...

An 88-year-old man who had been suffering from repetitive fever and abdominal pain every few months for several years was diagnosed with localized acute cholangitis and referred to our center. Various examinations, including computed tomography (CT) and endoscopic ultrasonography (EUS), revealed that the accessary hepatic duct was obstructed by clips used during laparoscopic cholecystectomy performed 7 years previously. It was not possible to approach the completely isolated duct via the transpapillary route...

Intrahepatic gallbladder perforation with abscess formation is an uncommon presentation of biliary disease. There is no consensus on how to treat this condition, with strategies varying from percutaneous drainage to open cholecystectomy and washout. We present a case of a novel, minimally invasive treatment, using endoscopic retrograde cholangiopancreatography to place a transcystic drain as a bridge to laparoscopic cholecystectomy.
