Abstract
Albeit generally safe procedures, endoscopic retrograde cholangiopancreatography (ERCP) and biliary stenting are associated with a non-negligible morbidity and occasional mortality. Due to the number and complexity of operative ERCPs currently performed, radiologists are increasingly faced with imaging investigation of suspected post-procedural complications. Timely diagnosis and optimal management require a combination of clinical and laboratory data with imaging appearances, aiming to triage those occurrences that require prolonged hospitalisation and interventional or surgical treatment.
Multidetector CT plays a pivotal role in the elucidation of post-ERCP complications and is warranted in case of suspicious intraprocedural events, physical signs or laboratory abnormalities. In selected patients MRI allows to image pancreatitis and abnormal collections without use of ionising radiation.
This chapter reviews with several imaging examples the commonest complications occurring after ERCP with or without biliary stenting. Knowledge of procedural details, an appropriate CT acquisition technique and familiarity with normal and abnormal imaging appearances are needed to diagnose and grade oedematous or necrotic pancreatitis, haemorrhages, duodenal perforation, iatrogenic infections and stent-related complications.
