To determine if disinfection, rather than sterilization, of laparoscopic equipment leads to an increase in the risk of postlaparoscopy infection, the authors analyzed data from a multicenter prospective study conducted by the Centers for Disease Control on the safety of sterilizing operations. From September 1978 through July 1981, 3903 women underwent laparoscopic tubal sterilization procedures in which the equipment was sterilized with ethylene oxide (58%) or disinfected with glutaraldehyde (42%). The overall risk of wound infection in each group was 1.5 per 100 women. The relative risk of wound infection for disinfection versus sterilization of the equipment was 0.5 when adjusted for differences in the two groups. The corresponding relative risk of pelvic infection was 1.2. These results suggest that laparoscopy equipment disinfected with glutaraldehyde is not associated with an increased risk of wound or pelvic infection compared with equipment sterilized with ethylene oxide.
