Evidences supporting the vascular etiology of post-double balloon enteroscopy pancreatitis: Study in porcine model

Figure 2 Pancreas immunohistochemistry. A: Expression of the VEGF in a normal parenchyma; B: Pancreatic acini with normal structure and nuclei, which express VEGF. In upper right corner a ischemic zone where less VEGF expression is shown, the pancreatic acini structure has been lost and nuclei are pyknotic. VEGF: Vascular endothelial growth factor.
