Magnetic resonance imaging (MRI) is a safe and universally available test that has much appeal to generalists and subspecialists evaluating patients with pancreatic disease. Testoni et al. report the clinical utility of magnetic resonance pancreaticocholangiography (MRCP) and secretin-enhanced MRCP in the evaluation of patients with asymptomatic abnormalities in pancreatic enzymes. The authors report that chronic pancreatitis changes will be seen in up to a third of patients with asymptomatic elevations in pancreas enzymes when compared with age-matched controls. The changes described on MRI and secretin-enhanced MRI are not in question, but the clinical significance of these changes is unknown. The authors rightly report that some of the changes seen may be age related, nonspecific, and of unknown clinical significance. Any new imaging and diagnostic test needs to be interpreted with caution until appropriate prospective clinical trials have been performed. It appears that secretin stimulation enhances the diagnostic accuracy of MRCP for the detection of minor changes in the pancreatic duct and parenchyma. Gastroenterologists are encouraged to proceed with cautious optimism when using MRI for the evaluation of early chronic pancreatitis.

Embryological development of the pancreas is a complex phenomenon and, therefore, it can have multiple developmental aberrations. Fortunately, the majority of these pancreatic ductal anomalies are asymptomatic with no clinical relevance and are incidentally detected during diagnostic cross-sectional imaging or endoscopic retrograde cholangiopancreatography (ERCP) or autopsy. Occasionally, pancreatic duct anomalies can result in symptoms like abdominal pain or recurrent pancreatitis.

Objectives: To develop and validate a radiomics nomogram based on a fully automated pancreas segmentation to assess pancreatic exocrine function. Furthermore, we aimed to compare the performance of the radiomics nomogram with the pancreatic flow output rate (PFR) and conclude on the replacement of secretin-enhanced magnetic resonance cholangiopancreatography (S-MRCP) by the radiomics nomogram for pancreatic exocrine function assessment.
Methods: All participants underwent S-MRCP between April 2011 and December 2014 in this retrospective study.

Disconnected pancreatic duct syndrome (DPDS) is an important and common complication of acute necrotizing pancreatitis. Endoscopic approach has been established as the first-line treatment for pancreatic fluid collections (PFCs) with less invasion and satisfactory outcome. However, the presence of DPDS significantly complicates the management of PFC; besides, there is no standardized treatment for DPDS.

Introduction And Importance: In children, acute recurrent pancreatitis is attributed to pancreato-biliary anomalies, hereditary pancreatitis and cystic fibrosis. Pancreatic divisum is a common congenital ductal anomaly that leads to recurrence of pancreatitis.
Case Presentation: A 13 years old female presented with clinical features of acute recurrent pancreatitis.
