ABSTRACT
OBJECTIVE:
We describe the feasibility and short-term outcome of our surgical technique to repair the lymph vessel disruption directly after axillary lymph node dissection during breast cancer surgery. This procedure is called immediate lymphatic reconstruction to prevent breast cancer treatment-related lymphedema (BCRL), which frequently occurs after axillary lymph node dissection. The surgical technique consisted of lymphaticovenous anastomosis (LVA) or lymphaticolymphatic anastomosis. We named the procedure lymphatic bypass supermicrosurgery (LBS).METHODS:
This study used a retrospective cohort design of patients with breast cancer between May 2020 and February 2023. LBS was performed by making an intima-to-intima coaptation between afferent lymph vessels and the recipient's veins (LVA) or efferent lymph vessels lymphaticolymphatic anastomosis.RESULTS:
A total of 82 patients underwent lymphatic bypass. The mean age of patients was 50 ± 12 years, and most had stage III breast cancer (n = 59 [72%]). LVA was the most common type of lymphatic bypass (94.6%). The median number of LVA was 1 (range, 1-4) and 1 (range, 1-3) for lymphaticolymphatic anastomosis. The median follow-up time was 12.5 months (range, 1-33 months). The 50 patients who had postoperative indocyanine green lymphography described arm dermal backflow stage 0 in 20 (40%), stage 1 in 19 (38%), stage 2 in 2 (4%), and stage 3 in 9 (18%) cases. The proportion of BCRL was 11 (22%), and subclinical lymphedema was 19 (38%) in this period. Most cases were in stable subclinical lymphedema (10, 58.8%). The 1-year and 2-year BCRL rates were 14% (95% confidence interval, 4%-23.9%) and 22% (95% confidence interval, 10.1%-33.9%), respectively.CONCLUSIONS:
Along with the emerging immediate lymphatic reconstruction, LBS is a feasible supermicrosurgery technique that may have a potential role in BCRL prevention. A randomized controlled study would confirm the effectiveness of the technique.Palabras clave
