Transgastric placement of IRE probes to target an enhancing pancreatic tail lesion in a pancreatic tail lesion in a nonsurgical patient. Again, notice the parallel placement of probes, bracketing the lesion. Transgastric needle placement (arrow) was necessary due to lack of an available window. This is generally safe with the 19G IRE probes. Unlike other ablative modalities with larger probe sizes, transversal of stomach and small bowel is deemed safe.
