Hemopatch Versus Axillary Drainage After Axillary Lymphadenectomy

Aspirative drainage continues to be the \"gold standard\" for the management of this post-surgical complication, even though it can lead to complications such as obstruction of the drainage, peritubal leakage of the seroma, etc. This may result in pain and reduction in mobility of the affected arm. Based on our positive clinical outcomes and the fact that there is not any published data available in the literature regarding this use of the patch, the investigators propose a multicentric, randomized controlled clinical trial, with the objective of comparing the Hemopatch® with the usual technique used (aspirative drainage) in terms of efficacy and safety. Hypothesis: Placing a Hemopatch ® instead of an aspirative drainage in women after undergoing axillary lymph node dissection during breast cancer surgery may reduce the appearance of seroma and consequently the need for a puncture, as well as the complications related to aspirative drainage.
