"No-Touch" Enhancement Significantly Reduces the Risk of Infection-Related Failure in Immediate Breast Reconstruction

Infection rates in prosthetic breast reconstruction after mastectomy vary widely, ranging from 1% to 35%, with meta-analyses reporting average infection rates of greater than 5%. This infection rate of greater than 5% is unfortunate for one of today's most commonly performed plastic surgical procedures. In an attempt to reduce infectious events, the author developed a "no-touch" protocol for performing breast reconstruction with tissue expanders and acellular dermis (ADM). This approach utilizes a transparent barrier drape and self-retaining retractor system patterned after similar orthopedic and urologic techniques that have proven to significantly reduce infection of implanted prostheses. Our preliminary results published in 2015 showed a significant improvement in infection rates. With this study, we assess the impact of the no-touch technique on a much larger number of patients.

Institutional review board approval was granted for a retrospective study of patients who underwent immediate breast reconstruction with tissue expanders and ADM from 2010 to 2017 by the author. Reconstructions prior to the institution of a no-touch protocol in 2014 were compared with those after the enhancement was instituted. A minimum of 60 days' follow-up was used to assess surgical complications. Demographic and outcome data were analyzed.

Immediate breast reconstruction with tissue expanders and ADM was performed on 133 patients (217 breasts) from 2010 to 2017. Sixty-nine patients (113 breasts) underwent reconstruction from 2010 to 2014 utilizing the traditional technique, and 64 patients (104 breasts) underwent reconstruction from 2014 to 2017 using the new no-touch enhancement applied by the author. Patients in both groups had similar demographics and comorbidity profiles. The only other technique variable besides the addition of no-touch was the trend toward the use of larger sizes of ADM in the later group (164 vs 108 cm). The rate of infection-related reconstructive failure dropped from 11.5% (13/113) to 1.9% (2/104) (P = 0.0054) after institution of the no-touch protocol.

Institution of a specific no-touch protocol to immediate breast reconstruction with tissue expanders and ADM lowered the risk of reconstructive failure due to infection 6-fold-11.5% to 1.9%. Comparative studies from other surgeons are encouraged.
