title: Current situation of endoscopic biliary cannulation and salvage techniques for difficult cases: Current strategies in Japan.
abstract: In the pancreatobiliary session at Endoscopic Forum Japan (EFJ) 2015, current trends of routine biliary cannulation techniques and salvage techniques for difficult biliary cannulation cases were discussed. Endoscopists from nine Japanese high-volume centers along with two overseas centers participated in the questionnaires and discussion. It was concluded that, currently, in Western countries, the wire-guided cannulation (WGC) technique is favored during initial cannulation attempts. However, the conventional technique using an endoscopic retrograde cholangiopancreatography catheter with contrast medium injection is still used as first choice at most Japanese high-volume centers. The WGC technique is used as the second choice at some institutions only. After failed biliary cannulation attempts, the initial salvage option preferred in most centers includes pancreatic guidewire placement, followed by precut techniques as the second salvage choice. Among several precut techniques, the free-hand needle knife sphincterotomy with cutting upwards from the pancreatic duct is most popular. Endoscopic ultrasonography-guided rendezvous technique is also carried out as a final salvage option at select institutions.
