Abstract    Endoscopic therapy plays an important role in acute biliary pancreatitis (ABP). Endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic ultrasound (EUS) are helpful in diagnosis and further therapy of ABP. Early endoscopic nasobiliary drainage (ENBD) , endoscopic sphincteropapillotomy (EST) and pancreatic duct stent placement can remove biliopancreatic obstruction, reduce pressure of bile duct and pancreatic duct, drain bile and pancreatic juice, release pancreatitis and reduce incidence of complications. However, severe complications such as hemorrhage, perforation, pancreatitis exacerbation and retroperitoneal infection can be caused by endoscopic therapy. Therefore, indications should be strictly controlled. Early ERCP should be performed only in patients with ABP complicated with acute cholangiolitis. Patients with SAP without acute cholangiolitis do not benefit from early ERCP except jejunum nutrition tube, and they should be observed closely.
