[Usefulness of intravenous contrast in pancreatic echoendoscopy. A case series]

The intravenous contrast (IV) allows for improving the diagnostic accuracy of echoendoscopy for many pathologic conditions. IV contrast provides a non-invasive method that through the use of real-time enhancement patterns (hypo, iso, and hypercaptation), a highly accurate histological diagnosis can be made by characterizing the microvasculature of an organ or a lesion. However, the lack of availability of IV contrast limited its use in our setting. We reported three cases of endoscopic ultrasound with IV contrast performed in the pancreatic department of National Hospital Eduardo Rebagliati Martins in Lima, Peru. We described the effectiveness of IV contrast in the diagnosis and the management of solid and cystic lesions in the pancreas.
