[Digestive endoscopy: biliary tract and pancreas]

New technological developments in endoscopic retrograde cholangiopancreatography and endoscopic ultrasound, both for diagnosis and treatment of biliary and pancreatic diseases, have opened up new scenarios in the recent years. For instance, removal of large bile duct stones with endoscopic sphincterotomy followed by large balloon dilation has been proven to be a safe and effective technique. Also cholangioscopy evolved in terms of better imaging, tissue acquisition and stones management. Self-expandable metal stents are used mostly for malignant diseases, but their role in benign diseases has also been deeply investigated in the last years. The rapid evolution in the field of radiofrequency brought new devices for safer ablation and palliation of biliary tumours. Self-expandable metal stents are also used for ultrasound-guided drainage of walled off pancreatic necrosis and for choledocoduodenostomy and cholecystogastrostomy
