Day after Gb surgery had an abd MRI said there was fluid around my pancreatic neck prob due 2 surgery is that bad. Can my pancreas have something wron?

Normal. Post op day one there is always fluid where the gallbladder used to live, liver and or pancreas. Assuming you had an MRI post op day to look for stones, but this cannot say anything about the neck of the pancreas. If the stones were there they should be seen inside the common bile duct or pancreatic duct, but the fluid post op day one is inconclusive.
