Abstract

Abstract Introduction : The harvest of the latissimus dorsi muscle for the realization of immediate breast reconstruction induces a large dorsal scar measuring up to 20 centimeters, while only the muscle is used. We present here the results of our experience of endoscopic harvesting of the latissimus dorsi muscle using 3D technology. Our main objective is to reduce the dorsal scar and second assess the functional consequences for patients. Methods: Between December 1st, 2015 , and June 1st, 2016, there were 7 patients who underwent latissimus dorsi endoscopic harvesting, with 3D technology, for an immediate breast reconstruction after a skin-sparing or nipple sparing mastectomy. Results: 4 patients had latissimus dorsi muscle with breast implant and 3 patients by latissimus dorsi muscle only. The age average was 55 years (range 45-70). The mean length of surgery was 250 minutes (range 150- 380). The mean length of hospitalization was 7 days (range 4-12 days). One patient treated for local recurrence had skin necrosis because of previous radiotherapy. Donor site seroma was the main post surgery drawback. Patients on average benefited from 3 evacuations (range 1-5) of 850ml (range 640-1270ml). Acceptance of the reconstructed breast was good in six cases, and poor in one case. Only one patient reported discomfort at the donor site 1 month after surgery. Conclusion: The endoscopic 3D latissimus dorsi flap harvesting allows to reduce donor site scar. There is no significant difference concerning complications or post-operative pain and functional discomfort between the endoscopic and classic harvesting procedure.
