Does reoperation predispose to postoperative wound infection in women undergoing operation for breast cancer?
Reoperations for breast cancer predispose to a higher risk of postoperative wound infections than primary procedures. We accomplished a retrospective chart review of 320 women who underwent multiple breast cancer procedures between 10/97 and 8/02. The mean number of procedures was 2.4 (range, 2-5). The overall incidence of wound infection was 6.1 per cent. Wound infections developed, on average, 12 days after surgery (range, 2-30). There was a statistically significant difference in the incidence of wound infection comparing the initial procedure versus the subsequent operation (1.6% vs. 9.4%, P < 0.001). This was also seen with reoperation after an operative biopsy compared to operation after a core biopsy (11.1% vs. 9.7%, P < 0.01). The incidence was increased to 22.0 per cent when the initial operation involved lymph node dissection (sentinel lymph node biopsy or complete axillary lymph node dissection). Wire localization did not increase the incidence of postoperative wound infecti
