After the surgery, you have to wait for the sutures to be removed, and after a week, you have to wait for the swelling to subside. Personally, it is recommended that you wait a month after the swelling subsides before eating hot pot. Barbecuing or whatever, as long as it's not spicy, it's ok.
After taking it, be careful to avoid spicy food and drinks.
As for soy sauce, vinegar, garlic, onion, etc., Western medicine does not pay attention to these, just eat them in moderation.
