2015 ASGE指南：消化内镜在良性胰腺疾病中的作用

A variety of benign pancreatic disorders can be diagnosed and treated with endoscopy. Endoscopy may be useful in the evaluation of idiopathic acute recurrent pancreatitis, suspected chronic pancreatitis (CP), or differentiation of focal CP from malignancy. EUS and endoscopic retrograde pancreatography (ERP) are the 2 most common endoscopic procedures used to evaluate the pancreas. EUS provides high-resolution imaging of both the pancreatic parenchyma and ductal structures and can be used to guide FNA or other interventional procedures. ERP is a more invasive procedure that provides information about pancreatic duct (PD) structures, but not the pancreatic parenchyma. Compared with EUS, ERP is associated with a higher risk of pancreatitis and is often reserved for therapeutic indications such as management of CP-associated PD strictures, stones, leaks, and symptomatic fluid collections.
