Safety and feasibility of irreversible electroporation for the pancreatic head in a porcine model

Figure 6 Masson trichrome staining of tissues in the ablation zone. A-C: Mild fibrosis (blue stained) was observed in pancreatic parenchyma on 7 d post-ablation (A), and the structures of pancreatic ducts (B) and vessels (C) remained intact; D-F: Staining of the duodenum wall showed that the structure of all layers was preserved although minimal injury to the mucosa layer was noted. Scale bars in (A) = 200 μm. Scale bars in (D) = 500 μm. Scale bars in (B and E) = 100 μm. Scale bars in (C and F) = 50 μm.
