Before going under anesthesia, I did talk with my GI doctor briefly. Apparently this remaining pseudocyst is not resolving, because there is a leak in the pancreatic duct. I did ask him why the radiologist needed to talk with him so urgently, and it turns out he was just wanting an update.
I did not talk with my GI doctor after the ERCP, but he did talk to my dad. It is my understanding that I have made a lot of progress in the last six weeks. They replaced the stent in the pancreatic duct, and hopefully things will heal up this time.
It sounds like I will have a follow up with the radiologist next week. My guess is they will inject dye into the drain catheter again (better that than into my veins).
