I assume by your question that you have already had the tummy tuck procedure and now it is being recommended that you have an abdominal hysterectomy. Ultimately, the GYN should be able to go through the same incision as your tummy tuck, but the problem will be entering your abdomen through the previous muscle repair. I would suggest talking to your GYN to make sure he/she is comfortable with operating through a previous tummy tuck incision and if not, perhaps your previous (or if not available, a new) plastic surgeon could be available to help with the procedure, though this may be difficult to coordinate. Another possibility is to ask your GYN if the hysterectomy can be done laparoscopically or vaginally or even with robotic assistance to avoid as much damage to your abdomen as possible. Best of luck with your surgery!
