You should get the specific instruction from the CT technologist for a successful study. Do not hesitate for asking a minimal volume. The gastric volume after a sleeve gastrectomy is usually less than 100 cc. Good luck!

The radiology department will be able to guide you as to the least amount of oral contrast that needs to be adjusted in order to do the CT scan properly. Good luck.
