quite an interesting thread. i am a surgeon, so i will give my take from that perspective. each pt i operate on (average 55 cases a month in surgery plus 60 to 80 colon and stomach scopes a month) gets the same talk about risks to surgery. this is the is the law, it's called providing informed consent. common risks to all procedures include bleeding, infection, chronic pain, scarring, need for further procedures. . . then other, more procedure-specific risks like anastamotic leak, blood clot, etc.
if you did not sign a piece of paper that states this and/or your surgeon did not inform you of these things, then you have a case. if you did, then one would have to prove that your surgeon deviated from the standard of care.
MRSA is a common bacteria nowadays and is normal skin flora (bacteria that populate our body as symbiants of sorts) for about 50% of the general population. it commonly inhabits nasal passages, skin and the perianal area. most healthcare workers (over 80%) are colonized with this bug today. you are probably in this group. your primary care doc could swab your nose or anus to figure this out for certain. so there is a good chance that the bug that caused your problems started out on your body. there's no way to know for certain, and that doesnt liberate you surgeon from wrong-doing, but it is something that you should know.
for better or worse, infectious complications are a part of our daily lives. we give antibiotics pre-op, we prep the surgical site with bacteriacidal concoctions, and for 1-2 people in a hundred, this sort of thing still happens. frustrating, but true.
