Immediate Lipo-Filling as a Novel Technique for Volume Replacement in Oncoplastic Breast Conservative Surgery.

backgroundWe aimed to evaluate the feasibility of immediate lipofilling as a volume replacement technique in breast conservative surgery (BCS) in terms of the volume of fat graft resorption after radiotherapy, patient satisfaction, and oncological safety. PATIENTS AND

methodsThis was a prospective study that included female patients with breast cancer, with small- or medium-sized breasts. The patients underwent BCS followed by lipofilling into the deformed areas away from the tumor site that resulted from direct closure of the tumor cavity. They were followed up for early and late postoperative complications, including recurrence. Volumetric computed tomography was performed before and after radiotherapy to determine percentage fat resorption. Postoperative patient satisfaction was assessed using the Kyungpook National University Hospital Breast Reconstruction Satisfaction Questionnaire.

resultsThe study included 54 female patients with a mean age of 47.57 ± 9.26 years. The mean follow-up period was 31.02 ± 4.47 months. Local recurrence was observed in three patients (5.56%). The volume reduction of the injected fat graft ranged from 10.15% to 55.67%, with a mean of 29.27 ± 10.06%. Fifty-two patients (96.30%) reported postoperative satisfaction, and nine of them expressed satisfaction only after a second lipofilling session.

conclusionsImmediate lipofilling as a volume replacement technique in BCS is a safe and simple technique without major complications. It has a locoregional recurrence rate similar to BCS alone, with an acceptable fat resorption percentage and high postoperative patient satisfaction.
