It's very unlikely rectal surgery would cause infection the prosthesis but it probably is a good idea to take prophylactic antibiotics in the advent of a temporary bacteremia.
What is the Likelihood of Having a Breast Implant Infection After Rectal Surgery?

Breast Implant Infections
Rectal surgery is no more likely to cause a breast implant infection than a dental procedure. Now that you have an implant in your body (and this also applies to hip/knee replacements and heart valves etc), you should take prophylactic antibiotics every time that you have a procedure to help kill off any microbes that may enter your bloodstream during a procedure. Most surgeons would provide this anyway, but it is useful to consider taking some broad spectrum antibiotics for two days prior to and a day or two after a procedure to be sure.

Risk of implant infection with remote site surgery
Rectal surgery, especially if elective, should not place you at risk of an infection in the blood stream. This would be the only way an implant could potentially be seeded by an infection. Standard protocol for rectal surgery would be the use of prophylactic antibiotics.

While there are no large studies that address this issue, common sense tells us that if you operate on a "dirty" area such as the mouth, the lower GI system, or the vaginal region, antibiotics should be used to protect medical devices such as breast implants from possible contamination and infection. Proper antibiotic coverage should significantly decrease the risk of infection though nothing can completely eliminate the possibility of infections. Be sure your surgeon uses the correct antibiotics before your surgery and rest easy since the chances of infection are minimal.
It is unlikely that you would acquire an infection of your breast implants while undergoing "rectal surgery". As a precaution I would recommend perioperative antibiotics while undergoing the "rectal surgery".
