Unfortunately, there is no way to tell what your vet will find when he goes in. If the first surgery included a partial pancreatectomy, this procedure cannot be repeated - so the second surgery will likely be a nodulectomy. Only advice is to make sure to do a good inspection of the pancreas as well as the rest of the abdomen. Some ferrets have 3 or more surgeries to control diabetes.
