There are two main indicators of endoscopic ultrasound (EUS) in acute pancreatitis: (1) suspicion of a biliary cause and intermediate probability of a common bile duct stone and (2) idiopathic acute (recurrent) pancreatitis. In cases of suspected biliary pancreatitis, EUS reliably selects patients for therapeutic endoscopic retrograde cholangiography. In approximately two-third of cases with idiopathic acute pancreatitis, EUS reveals the etiology of acute pancreatitis (biliary microlithiasis and sludge, common bile duct stones, pancreas divisum and other abnormalities of the pancreatobiliary ducts, chronic pancreatitis, intraductal papillary mucinous neoplasms, and solid pancreatic tumors).

Role of endoscopic ultrasound during hospitalization for acute pancreatitis
World Journal of Gastroenterology, 2010
Endoscopic ultrasound (EUS) is often used to detect the cause of acute pancreatitis (AP) after the acute attack has subsided. The limited data on its role during hospitalization for AP are reviewed here. The ability of EUS to visualize the pancreas and bile duct, the sonographic appearance of the pancreas, correlation of such appearance to clinical outcomes and the impact on AP management are analyzed from studies. The most important indication for EUS appears to be for detection of suspected common bile duct and/or gall bladder stones and microlithiasis. Such an approach might avoid diagnostic endoscopic retrograde cholangio-pancreatography with its known complications. The use of EUS during hospitalization for AP still appears to be infrequent but may become more frequent in future.

Endoscopic ultrasonography (EUS) can assess both parenchymal and ductal changes with the possibility of performing transgastric and transduodenal imaging of the pancreas. Endoscopic ultrasonography, because of its ability to show the pancreas in more detail but without the inherent risk of ERP, has been used in the diagnosis of chronic pancreatitis. 10-12 It has been reported that EUS is superior to US and CT and comparable to that of ERP, especially in the diagnosis of mild and moderate chronic pancreatitis. In this study, we aimed to determine the role of EUS in the evaluation of cases with chronic pancreatitis and patients referred for unexplained abdominal pain and/or suspected CP. With this aim, we compared the results of EUS and ERP in the patients with CP. Additionally, we investigated endosonographic features of early CP in cases with chronic abdominal pain of suspected pancreatic origin.

Background: Etiology of acute pancreatitis (AP) remains idiopathic in 30% of patients. Endoscopic ultrasound (EUS) has been shown to increase the diagnostic yield in patients with idiopathic AP (IAP). Aim: The aim of this study was to evaluate the role of EUS in achieving etiological diagnosis in patients with IAP. Materials and Methods: Consecutive 192 patients with IAP were evaluated prospectively with EUS over a period of 2 years. Patients who had no etiological diagnosis for AP after detailed history, clinical examination, laboratory investigations, and magnetic resonance cholangiopancreatography were included in the study. Results: The mean age of patients was 34.6 ± 12 and male:female ratio was 2.1:1. Of these, 135 patients had gallbladder intact (Group A) and 57 patients had undergone cholecystectomy (Group B). In Group A, EUS identified a possible cause in 79 (58.5%) patients; microlithiasis (n = 48), chronic pancreatitis (CP) (n = 23), common bile duct (CBD) and gallbladder...
Endoscopic ultrasound and pancreatic applications: what the radiologist needs to know
As the technology has improved, endoscopic ultrasound (EUS) has taken on an important role in the diagnosis of a number of different neoplastic and non-neoplastic pancreatic diseases. EUS can provide high-resolution images with subtle anatomic detail, and has also taken on an important role in the targeted biopsy of the pancreas and adjacent structures. This review seeks to familiarize radiologists with the role of EUS in the diagnosis of chronic and autoimmune pancreatitis, solid pancreatic masses, and cystic pancreatic neoplasms.
Endoscopic ultrasonography to evaluate pancreatitis
Cleveland Clinic Journal of Medicine, 2012
Endoscopic ultrasonography (EUS) has become a wellaccepted test in the workup of acute and chronic pancreatitis. However, further studies are needed to define its diagnostic role in patients with recurrent acute pancreatitis and minimal-change chronic pancreatitis.

Endoscopic ultrasonography (EUS) is currently an integral tool for work-up of pancreaticobiliary neoplasms. Tissue acquisition by EUS is possible with fine-needle aspiration (FNA) cytology and histology. However, FNA still carries some limitations and risks of complications. The use of image-enhanced EUS may improve detection and characterization of pancreaticobiliary neoplasms and complement FNA. The present article aims to provide an overview of the current development of contrast-enhanced imaging and elastography in EUS and their potential application in the diagnosis of pancreaticobiliary diseases.
