Endoscopy is the first-line therapy for most post-liver transplantation anastomotic biliary strictures. Passage of a guidewire through the stricture is done under fluoroscopic guidance. Although anastomotic biliary strictures are usually short, they can be tight, fibrotic, and angulated, sometimes not allowing guidewire passage. Additional interventions (percutaneous transhepatic cholangiograph...

Nowadays, cholangioscopy is an established modality in diagnostic and treatment of pancreaticobiliary diseases. The more widespread use and the recent development of new technologies and accessories had renewed the interest of endoscopic visualization of the biliary tract, increasing the range of indications and therapeutic procedures, such as diagnostic of indeterminate biliary strictures, lit...

pancreatic stent proximal migration is a well known complication of pancreatic duct stenting, which occurs in about 5-6% of cases. serious complications should be avoided by retrieval of the stent via different endoscopic techniques. we report a new technique previously reported only once (in a pancreatic duct with underlying pathology), to remove the proximally migrated pancreatic stent in a n...

Intraductal papillary mucinous neoplasms (IPMNs) are epithelial neoplasms treated with surgical resection when appropriate. We present a 79-year-old man with jandice refractory to endoscopic stenting. Biliary radiofrequency ablation (RFA) with cholangioscopy was used as palliation of obstructive jaundice due to a mucin-producing pancreatic IPMN with fistulous biliary communication. Clinical imp...

BACKGROUND Endoscopic papillotomy is successful in more than 95% of the cases of choledocholithiasis. For patients with difficult bile duct stones not responding to mechanical lithotripsy, different methods for stone fragmentation have been developed. AIM To compare the results of laser lithotripsy with a stone-tissue recognizing system, when guided by fluoroscopy only or by cholangioscopy. ...

Portal vein thrombosis with cavernous transformation is a rare cause of biliary obstruction. Portal biliopathy is a term that refers to abnormalities in the intrahepatic and extrahepatic biliary tract, gall bladder, and cystic duct secondary to portal hypertension. Patients may be asymptomatic, but they can also present with abdominal pain, jaundice, and fever. We present the case of a 61-year-...

BACKGROUND Although peroral direct cholangioscopy (PDCS) is emerging as an alternative to traditional mother-daughter cholangioscopy, it is associated with high failure rates. The aim of the present study was to evaluate the ability to insert and carry out interventions using a prototype multi-bending PDCS. PATIENTS AND METHODS Prospective, observational clinical feasibility study was done in...
