Comparative analysis of direct pancreatic function testing versus morphological assessment by endoscopic ultrasonography for the evaluation of chronic unexplained abdominal pain of presumed pancreatic origin.

Objectives: The diagnosis of "minimal change" chronic pancreatitis (MCCP) is often considered when conventional imaging studies are unrevealing in a patient population with abdominal pain of presumed pancreatic origin. Direct pancreatic function testing using secretin as a secretagogue (ST) has been considered the most sensitive method to diagnose MCCP but is not widely available to clinicians. Endoscopic ultrasound (EUS) allows detailed imaging of pancreatic architecture, but the sensitivity and specificity for MCCP remain to be determined.

Prevalence of gastroparesis in patients with small duct chronic pancreatitis.

Introduction: The most common symptoms of chronic pancreatitis are abdominal pain, diarrhea, and weight loss. The abdominal pain has no consistent pattern, and nausea and vomiting commonly occur simultaneously. Gastroparesis may produce similar symptoms.
