BACKGROUND: Radical lymph nodes dissection (RLND) is the standard procedure for regional control of disease in patients with metastatic melanoma (stage III). Because of its aggressiveness, lymphorrhoea is a constant problem in postoperative.
METHODS: In this prospective nonrandomized study with a retrospective analysis of data, patients undergoing surgical treatment of axillary or iliac-inguinal RLND received standard treatment plus a collagen-fibrin sealant patch (TachoSil) (N.=50) or standard treatment alone (N.=50). The first endpoint was the comparison between the treated population and the control group, in terms of persistence of drainage and average daily volume of lymphorrhoea. The second aim was to relate patients’ BMI, volume of lymphorrhoea and time of drainage in the two groups.
RESULTS: In the comparison between the two groups receiving or not the treatment with collagen-fibrin patch, we found an average difference both in the volume of daily lymphorrhoea (42.91±6.61 cc) and in the persistence of drainage (9.292±1.644 days) with P value <0.0001. Besides, the collagen-fibrin patch was actually effective in reducing lymphorrhoea and time of drainage, regardless of patients’ BMI.
CONCLUSIONS: The results of this study confirm and support the starting thesis: TachoSil is an effective tissue sealant able to reduce lymphorrhoea and drainage removal times following a radical lymphadenectomy, independently from the BMI.
