Successful Treatment of Lymphocele after Inguinal Lymph Node Dissection with OK-432 Sclerotherapy: A Report of Two Cases

Lymphocele is a frequent complication in the early postoperative period following lymph node dissection. In this study, we performed sclerotherapy with OK-432 (picibanil) in two cases of lymphocele after groin lymph node dissection. Case 1 involved a 55-year-old male patient who underwent bilateral groin lymph node dissection. A lymphocele developed in the groin after drain removal. The lymphocele in the left groin worsened after the patient resumed work. After four sessions of sclerotherapy with OK-432, the lymphocele resolved. Case 2 involved a 67-year-old male patient who also underwent bilateral groin lymph node dissection. The lymphocele in the left groin persisted despite the initial treatment, but disappeared after four sessions of sclerotherapy with OK-432. The treatment duration for cases 1 and 2 were 51 and 23 days, respectively. Both cases showed mild dermal back flow on lymphoscintigraphy several years after surgery. Sclerotherapy with OK-432 resulted in acceptable results.
