Yes, depends on Dr. but Honestly from what I have read. I think being on a pre op Diet is the best. It helps shrink the liver which makes surgery easiery for everyone around. I was unable to do FULL liquids but did 2/3 drinks a day and ate salads, 5oz chicken, or fish, VERY low carbs. It helps liver. Then 24 hours before surgery I did full clear liquids, popcicles, broth, jello, water. It was hard but so glad I did!
Good Luck!!!!!!!
