Similar. 1.6 cm pNET. I had an opinion to wait as well but wanted a second opinion to say the same but it was to remove it. Mine was mid pancreas but very close to the SMV. 3rd opinion was to remove so I chose to do that. All scans showed gall bladder stones which I’ve never had that kind of event. I was told about the splenectomy and chose to have them preserve mine.
So since my pNET was small but also squishing into the pancreatic duct making half my pancreas wither away, I did it with a gall bladder removal and preserving the spleen but vein ‘tore’ which made it become an open surgery and they patched the tear. Well the spleen infarcted and now is liquifying so it’s useless. Should have had it removed. I’m glad I did it. April 23. Turns out it had spread into one lymph node and waiting now for an oncology endocrinologist to see if we do any further treatment. My story. All the best!
