Prophylactic antibiotics for excision of premalignant vulvar lesions: A pilot randomized controlled trial.

ABSTRACT

No prospective data have been described to inform guidelines on antibiotic prophylaxis for partial vulvectomies. Thus, we conducted a single-center, pilot, double-blind randomized controlled trial to assess the effectiveness of prophylactic antibiotics to prevent wound complications after partial vulvectomies. Patients were randomly assigned 11 to preoperative antibiotics or no preoperative antibiotics. The primary outcome of 30-day postoperative wound complications occurred in 31 (62 %) of all patients, with no differences between groups. The most common wound complications were superficial separation (54.2 % antibiotic prophylaxis vs. 65.3 % no prophylaxis, p = 0.37) and surgical site infection (0 % antibiotic prophylaxis vs 7.7 % no prophylaxis, p = 0.49). However, this study was limited by differences in patient characteristics between the groups. This study provides data to perform power calculations for a trial examining the effect of preoperative antibiotics on surgical site infection.
