- Brief Summary
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.
- Detailed Description
1. Introduction:
In the surgical management of breast cancer, a conservative approach is the "gold standard" for the mammary region. For the axillary region, however, this depends on the results of the sentinel lymph node biopsy (SLNB) with axillary lymph node dissection (ALND) continuing to be an indispensable procedure when the disease reaches this level.
The complications that arise from this procedure can be divided in two groups: 1) early: seromas and nerve lesions and 2) late: lymphedema, functional disorders in shoulder movement and post-mastectomy pain syndrome.
Seromas are the most frequent complications after an ALND. In themselves, they do not carry a high risk of morbidity. However, they delay healing of the surgical wound, increasing the risk of infection and number of ambulatory visits and furthermore, resulting in a deferral in the start of adjuvant therapies such as radio and chemotherapy.
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.
Hemopatch® is a hemosthatic sealer made from reabsorbable collagen. It comes in the from of patch, with CE marking that is already being used in the clinical setting in Spain and the rest of Europe.
Taking into account the factors that reduce seroma formation after ALND and the characteristics of the patch, its application after surgery could be useful in preventing seroma formation. More specifically, the patch has proven to act as a
* Hemosthatic, improving the first phase of inflammation
* Adhesive, reducing the dead space left after ALND
* Sealer, decreasing the exudate
2. Rationale Based on this premise and in the context of a clinical protocol after the introduction of the patch in daily clinical practice, it was used on 28 patients that underwent ALND, obtaining favourable clinical results. This is 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.
3. Hypothesis Placing a Hemopatch ® instead of an aspirative drainage in women after undergoing ALND 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.

Group Intervention Description aspirative drainage Aspirative drainage Drainage is the usual treatment after axillary lymphadenectoma for breast cancer Hemopatch hemopatch The hemopatch group will be the group without drainage and with a product patch
- Primary Outcome Measures
Name Time Method complications from 24 hours until there is no complications, assessed up to 2 months Other complications collected throughout the study include: bruising (yes / no), pain (yes / no), problems with aspiration drainage (yes / no)
To develop seroma after surgery Percentage, through study completion, an average of 2 months Percentage of patients that receive Hemopatch® that develop seroma after surgery and percentage of patients that receive that develop seroma after extraction of the aspirative drainage.
total volumen of the seroma from 24 hours until there is no seroma, assessed up to 2 months The initial control will be performed 24 hours after the intervention, maintaining AD if the volume is greater than 30ml. All patients will be seen 7 days after surgery. The follow-up time will be weekly until there is no seroma, measuring the volume of the seroma extracted by puncture,
Seroma punctures through study completion, an average of 2 months the total number of punctures needed
- Secondary Outcome Measures
Name Time Method the costs through study completion, an average of 1 year Compare the costs of both procedures by quantifying the costs of materials and consult time used in both procedures
quality of life in patients 1 week after surgery with Eortc QLQ-BR23 Compare the quality of life in patients after receiving either of these procedures using the Eortc QLQ-BR23 survey
body mass index weight (kg) / height (m2). In the first consultation body mass index
