pancreatic ductal stricture
Narrowing of the main pancreatic duct that may indicate malignancy or benign inflammatory disease.
Full Definition
Pancreatic ductal stricture refers to abnormal narrowing of the main pancreatic duct, which can result from various pathologic processes including malignancy, chronic pancreatitis, or post-surgical changes. The stricture often presents with upstream ductal dilation and may cause symptoms related to pancreatic exocrine insufficiency or pain. Distinguishing malignant from benign strictures is challenging and often requires combination of imaging, tissue sampling, and clinical correlation. Endoscopic and surgical interventions may be necessary for both diagnostic and therapeutic purposes.
Usage
Usage note: Often accompanied by description of upstream ductal changes in imaging reports.
