The Scarless Neo-Umbilicus in DIEP-Flap Breast Reconstruction

Abstract

While the DIEP (deep inferior epigastric perforator) flap has become the gold standard in autologous breast reconstruction due to its favourable tissue characteristics and preserved abdominal wall function, a constant attempt is done to improve the outcome of the donor site. Even if just a small detail, the umbilicus has a big impact on the overall aesthetic outcome of the donor site. As an already established technique in abdominoplasties, we introduced the neo-umbilicus as the standard procedure for DIEP donor site closure. The aim of this study was to assess the aesthetic outcome of this neo-umbilicoplasty technique in DIEP-flaps. This is a single-center cohort study. A total of 30 consecutive breast cancer patients were treated during a period of 9 months with a mastectomy and an immediate reconstruction with a DIEP-flap. In all patients, the reconstruction of the umbilicus was done by an immediate neo-umbilicoplasty technique, consisting of a cylindrical fat resection at the new loco typico and fixation of the dermis directly to the rectus fascia. All patients were photographed in a standardised setting. Subjective patient satisfaction was assessed with a survey consisting of three questions and aesthetic outcome was evaluated by an independent professional panel consisting of three plastic surgeons. The results were compared to a previous cohort of conventional umbilicoplasties in DIEP-flap patients. Twenty-six patients participated in the follow-up study. There were no wound complications associated with the neo-umbilicus. Questionnaire results demonstrated high but not statistically significant different patient satisfaction. The panel scores were statistically significant (p < 0.05) better for the neo-umbilicus reconstructions. The aesthetic outcome was rated higher in patients with a higher BMI compared to those in patients with a low BMI. The creation of a neo-umbilicus at the donor site after DIEP-flap breast reconstruction is a quick and safe technique and leads to a superior aesthetic donor site result.
