Preventing Seroma Formation After Axillary Lymph Node Dissection for Breast Cancer by Early Vacuum Assisted Closure

Study Overview
=================
Brief Summary
-----------------
Axillary dissection is the standard treatment for breast cancer patients with positive nodes. However, seroma formation after axillary dissection remains the most common early complication to breast cancer surgery. It can delay the initiation of adjuvant therapy, predispose to wound infection, delay wound healing and has also been linked to arm lymphoedema. Based on some studies and our experience that vacuum assisted closure （VAC）is effective in complex wound failures following axillary dissection and groin dissection, we use VAC to prevent seroma formation after extensive axillary dissection. This study is aimed to evaluate the efficacy, safety and economics benefits of early VAC application on postoperative complications and wound healing after extensive axillary dissection in comparison to conventional suction drain.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Active Comparator: Axillary dissection<br>Axillary dissection is a surgical procedure that incises (opens) the armpit (axilla or axillary) to identify, examine, or remove lymph nodes (small glands, part of the lymphatic system, which filters cellular fluids). | Procedure: Axillary dissection<br> <br> |
| Experimental: vacuum assisted closure<br>Vacuum assisted closure (also called vacuum therapy, vacuum sealing or topical negative pressure therapy) is a sophisticated development of a standard surgical procedure, the use of vacuum assisted drainage to remove blood or serous fluid from a wound or operation site. | Procedure: vacuum assisted closure in experimental arm<br> <br> |
