Abstract

Across Europe, the number of patients dying from pancreatic ductal adenocarcinoma (PDAC) has increased by more than 60% since 1990. Early detection of PDAC and risk stratification of its cystic precursor lesions facilitates long-term survival. A majority of small solid pancreatic lesions are not PDAC, but pancreatic neuroendocrine neoplasms, metastases, and a variety of other entities, most of them associated with a much better outcome. In surgical cohorts operated for the suspicion of PDAC, 5–13% of cases have a final diagnosis other than PDAC, in particular focal autoimmune pancreatitis. Therefore, early detection and precise differentiation of solid and cystic pancreatic lesions is a diagnostic challenge. This chapter reviews the pivotal role of multimodal EUS imaging including B-Mode, contrast-enhanced techniques, and elastography for the reliable characterization of focal pancreatic lesions.
