When you wake up from the anesthesia, you will find that a tube may be placed in your abdominal cavity to drain any fluid that may collect during or after surgery. This drain is usually removed on the second or third day after operation as the amount of fluid drained gradually decreases. After surgery, you will not be allowed to eat or drink for 12-24 hours. On the morning of the day after surgery, you will started on liquids as recommended by your physician. This diet will further be reviewed and gradually increased by your dietician.
