LYMPHA: Eliminating the Burden of Lymphedema in Patients Requiring Nodal Dissection

Lymphedema is the build-up of lymph fluid in the body's tissue causing chronic, debilitating swelling. This commonly occurs as a result of a disruption of the lymphatic system during lymph node dissection surgeries. In melanoma patients, the incidence of lymphedema ranges from 5-10% in the arms following an axillary dissection, and 28-40% in the legs following groin dissection. LYMPHA (LYmphatic Microsurgical Preventive Healing Approach) is an innovative microsurgical technique where blocked lymphatic vessels are drained into the blood circulation by surgically creating a shunt between a lymphatic channel and a blood vessel called a lymphatic-venous bypass. Recently, LYMPHA has been shown to prevent lymphedema when performed at the time of nodal dissection. We propose a prospective pilot study evaluating the practice of the LYMPHA technique for the primary prevention lymphedema at The Ottawa Hospital. The novel use of the LYMPHA technique holds the potential to prevent lymphedema rather than to attempt to treat it once it has already progressed and as a result will not only improve the quality of life of the cancer patients, but also decrease health care costs associated with treating lymphedema.
