Hello 'ere30' thanks for your question. Although your history of drug-resistant infection does put you at a higher risk for postoperative complications, I would say it is not prohibitive as long as you do not have any active infections and overall you are healthy. It sounds like you have a symptomatic hernia that has already been incarcerated once, and it would be recommended to get your hernia fixed asap given your higher risks of strangulated hernia recurrence with possible formation of necrotic bowel, sepsis, and death. It is up to you if you want to pursue a cosmetic tummy tuck at the same time, but the risks of postop infection is not zero, especially with your history of recent infection with colonization of the bacteria on your skin. Be sure you seek consultations with board-certified plastic and general surgeons +/- infectious disease specialists to go over your options in more detail so that you can make an educated decision regarding what to do. Good luck!
I would proceed cautiously. I would ask your PS to confer with your infectious disease doctor and see what they think. Should you be treated before hand or cultured to be certain you are not carrying a resistant bacteria.
Any time that you have a resistant bacterial infection you have to be cautious about surgery. This is because you are likely colonized with this organism. Several precautions can be taken to minimize your risk of infection such as washing with antimicrobial soap before surgery and prophylax with antibiotics that was sensitive to your original infection and to get an IV perioperative dose.
In general, the infection rate in elective cosmetic surgery is quite low, but having gone through that experience I can appreciate your concern. This is a question for your infectious disease expert and plastic surgeon to confer on prior to scheduling any surgery.
