Advances in cryoablation for pancreatic cancer

Figure 5 Comparisons between computed tomography images of pancreatic carcinoma before, during and 1. 5 mo after cryoablation. A: The tumor at stage IV (red arrows) is 4.5 cm × 4.6 cm × 3.8 cm in size; B: The cryoprobe was inserted via the stomach approaching the tumor mass (yellow arrow); cryoablation was performed after the pancreatic tumor was completely encased within the ice ball (green arrows); C: The center of the tumor mass (red arrows) 1.5 mo post-cryoablation displays shrinkage with no enhancement of the tumor.
