Tuboovarian abscess following laparoscopic sterilization with silicone rubber bands

Laparoscopic tubal sterilization utilizing Silastic rings generally has been free of infection except when technical complications occur during the procedure. The development of a unilateral tuboovarian abscess in 2 women who had undergone uncomplicated laparoscopic tubal interruption 1 month earlier is reported. In both patients, the pathogens cultured from abscess and/or blood were common members of vaginal-cervical flora, suggesting the infection occurred after the procedure via the ascending route.
