Abstract

Chronic pancreatitis (CP) is a fibroinflammatory disease characterized by irreversible destruction of pancreatic tissue. With the development of the disease, it may lead to exocrine and/or endocrine insufficiency. CP is one of the common diseases that cause abdominal pain, which will not get permanent spontaneous relief as the disease evolves. The American College of Gastroenterology clinical guidelines recommend computed tomography or magnetic resonance imaging as the first-line examination for the diagnosis of CP. CP common imaging findings include pancreatic atrophy, irregular dilatation of the pancreatic duct, calcification of pancreatic parenchyma, pancreatic duct stones, etc. In clinical practice, whether any correlations between CP-induced abdominal pain patterns (no pain/constant/intermittent pain) and corresponding imaging findings present are not well known. Therefore, this review aims to comprehensively sort out and analyze the relevant information by collecting lots of literature on this field, so as to construct a cross-bridge between the clinical manifestations and imaging manifestations of CP patients. Also, it provides an imaging basis and foundation for the classification and diagnosis of abdominal pain types in clinical CP patients.

Keywords: Chronic pancreatitis; Pancreatitis; Abdominal pain; Computed tomography; Magnetic resonance imaging

Core Tip: Chronic pancreatitis (CP) is a fibroinflammatory syndrome. On the one hand, pain is the most common clinical manifestation of CP. On the other hand, computed tomography (CT)/magnetic resonance imaging (MRI) is the most commonly used imaging examination for CP, and the American College of Gastroenterology clinical guidelines recommend CT or MRI as the first-line examination for the diagnosis of CP. However, there is no review on whether there is a correlation between pain and CT/MRI. For this reason, this article focuses on summarizing the relationship between the pain patterns or types of the CP and the corresponding CT/MRI imaging findings, which is conducive to the integration of relevant and scattered contents, and is conducive to building a cross-bridge between clinical manifestations and imaging findings of CP patient. At the same time, it will promote academic exchanges between different medical centers as well as scientific research and teaching.
