Modified ilioinguinal node dissection for metastatic melanoma

: Standard ilioinguinal node dissection for melanoma has substantial cost and morbidity. Beginning in 1988, we modified the procedure in hopes of reducing side effects without compromising survival. : Dissection was standard except for preservation of saphenous vein and femoral sheath and omission of sartorius muscle transfer. To date, 19 patients with recurrent melanoma in the groin have had the procedure, 6 for N1 disease and 13 for N2, M1 metastases. : Average hospital stay was 4.5 days (range 3 to 7). Postoperative edema occurred in 1 (5%) patient. Disease-free survival at 40 months was 66% for N1 disease and 26% for N2, M1 metastases. : Modified ilioinguinal node dissection appears to reduce cost and morbidity of treating recurrent melanoma in the groin without compromising survival.
