Treatment of lymphocele with negative pressure wound therapy post inguinal mass excision: A case-report

A lymphocele is defined as an atypical collection of lymphatic fluid not bordered by distinct epithelial lining, which develops in anatomic compartments. Inguinal lymphocele is a common complication of surgery in the inguinal region, with an incidence ranging from 1 to 87 %. This report summarizes the management of an inguinal lymphocele post excision of an inguinal mass.

Herein, we present a case in which an inguinal lymphocele developed four months post excision of an inguinal mass, which was later diagnosed as lymphoma and treated with iliac chain radiation therapy. The conservative treatment with lymphocele drainage, compression dressing and prophylactic antibiotic was initially implemented. As the patient did not respond to conservative treatment, the surgical strategy consisted of excision of lymphocele associated with lymphatic ducts ligation. Negative pressure wound therapy completed the treatment.

Non-surgical treatment of lymphocele developing from lymphatic injure during groin dissection is not rarely unsuccessful. Surgical options include lymphocele excision with either ligation of the lymphatic ducts or lymphatic-venous shunts between afferent lymphatics and the collateral branch of great saphenous vein. Vacuum-assisted closure therapy assists the wound healing process by increasing blood flow, removing inhibiting factors of wound healing and decreasing the bacterial count.

Inguinal lymphocele that is not reabsorbed or does not resolve with conservative treatment should be surgically treated. Lymphocele excision with ligation of lymphatic vessels, followed by negative pressure wound therapy appears to be a safe and effective approach.
