Surgical Approach to Lymphedema Reduction.

PURPOSE OF REVIEW

For patients who have or may develop lymphedema due to oncologic resection, surgical options are available to prevent and treat this chronic disease. Here, we review the current pathophysiology, classification systems, surgical preventive techniques, and treatment options for lymphedema reduction.

RECENT FINDINGS

Preventive surgical techniques, including de-escalation of axillary surgery, sentinel lymph node biopsy (SLNB), axillary reverse mapping (ARM), and lymphedema microsurgical preventive healing approach (LYMPHA), have been shown to reduce the incidence of lymphedema. Water displacement remains the gold standard for measuring limb volume and classification of lymphedema; however, lymphoscintigraphy and ICG lymphography are two novel imaging techniques that are now utilized to characterize lymphedema and guide management. Complete decongestive therapy (CDT) remains the mainstay of treatment. Vascularized lymph node transfer (VLNT) and lymphovenous bypass have shown promising results, particularly in advanced lymphedema stages. Combination therapy, incorporating both surgical and non-surgical approaches to lymphedema, yields best patient outcomes. Lymphedema is a chronic disease wherein management requires a combination of surgical and conservative treatments. Standardization in lymphedema staging, key outcome indicators, and quantitative data will be critical to establish the absolute best practices in lymphedema diagnosis and treatment.
