Abstract
Endoscopic retrograde cholangiopancreatography (ERCP) is a cornerstone procedure for the diagnosis and management of pancreatic and hepatobiliary diseases. Although its diagnostic role has been increasingly supplanted by noninvasive imaging modalities such as magnetic resonance imaging (MRI) and magnetic resonance cholangiopancreatography, the therapeutic applications of ERCP have continued to expand. ERCP is widely used and has a generally favorable safety profile. However, it is important to recognize expected post-procedural imaging findings and serious complications that can arise. The increasing complexity of therapeutic interventions and the growing volume of procedures have led to a higher incidence of complications that often present with overlapping clinical and laboratory features, underscoring the critical role of imaging in differential diagnosis. This review focused on the typical normal ERCP findings and the imaging characteristics of common complications, including pancreatitis, bleeding, ERCP-related infections, perforations, and stent-related complications. Computed tomography (CT) is particularly valuable in timely recognition, management, and surgical decision-making for these complications. Furthermore, MRI offers a radiation-free alternative for managing complications in selected patients. Therefore, radiological modalities, particularly CT and MRI, are critical tools for the rapid diagnosis, management, and surgical decision-making processes for post-ERCP complications.
Core Tip: Endoscopic retrograde cholangiopancreatography (ERCP) is a standard procedure for treating pancreaticobiliary diseases that was driven by technological advances and improved procedural feasibility. However, the widespread use of ERCP is accompanied by a range of potential complications. Imaging modalities are frequently relied upon to identify, classify, monitor, and manage ERCP-related complications. Differentiating normal post-procedural changes from pathological findings is essential. This review provided a comprehensive overview of the normal post-ERCP imaging appearances and the spectrum of potential complications.
