Yes, the hole closes up immediately upon removal. It will form a small "crust" like scab on the hole which will fall off in two weeks or so ( that was my experience ). Nothing for her to do except be glad it's gone. Regarding your comment about her already eating, the Doctor would not have removed unless she had shown the ablility to eat. Worse thing you can do is remove the PEG before you can demonstrate ability to take in calories on your own. Best of luck to her in her recovery.
