ThP1.13 - Short term safety outcomes of immediate pre-pectoral implant based reconstruction

Abstract

Abstract Aims In the UK up to 43% of women undergo immediate breast reconstruction (IBR) following mastectomy for breast cancer. Implant reconstruction is the commonest form of breast reconstruction and pre-pectoral techniques have been introduced with the aim of improving cosmetic outcome and avoiding animation. To assess the safety of pre-pectoral implant based breast reconstruction (PPBR), including infection rates, 30 day re-admission to hospital, need for unplanned surgery and implant loss at 3 months. Methods A retrospective study of 80 consecutive women who underwent PPBR for breast cancer or risk reduction between October 2020 and October 2023. Demographic, operative and complication data were collected. Results Eighty women (70 cancer, 8 risk reducing and 2 cancer/risk reducing) underwent 94 PPBR procedures (80 Skin sparing mastectomies and 14 Nipple and skin sparing mastectomies) with a mean age of 51.5 (range 28 to 79) years and a BMI of 25.2 kg/m2. 7 (8.8%) of women were smokers. The mean implant size used was 385cc (range 160cc to 650cc) with a mean breast weight of 448.6g (range 45g to 1700g). 10 (12.5%) women required oral antibiotics for wound infection with a further 2 (2.5%) women requiring re-admission within 30 days for IV antibiotics. 17 (21.3%) developed a seroma with 8 (47.1%) requiring drainage. No implant losses were recorded within 3 months of reconstruction. Conclusion We have demonstrated that PPBR is a good option for patients of a wide age range with a large variation in breast size with minimal complications and no implant losses.
