Which is correct
1-The doctor operated his appendix.
2-The doctor operated on his appendix.

I know that one says 'operate on somebddy' and not 'operate somebody'. But I don't know how to use the verb with a body part.

    On is correct here. Either it's a heart operation or an appendix operation (where heart and appendix are adjectives), or it's operated on his heart, operated on his appendix.

    Ordinarily you would not operate on an appendix; you would operate on the patient and remove the appendix. It is not usually repairable.

    Operate on suggests that a repair or correction is being made to that body part. So operate on a heart is OK, but you remove defective appendixes, you don't repair them.
