Prospective assessment of postoperative complications and associated costs following inguinal lymph node dissection (ILND) in melanoma patients.

BACKGROUND: We prospectively assessed the incidence, risk factors, and costs associated with wound complications and lymphedema in melanoma patients undergoing inguinal lymph node dissection (ILND). MATERIALS AND METHODS: A total of 53 melanoma patients were accrued to 2 trials (June 2005 to July 2008) that included prospective evaluations of postoperative complications; 30-day wound complications included infection, seroma, and/or dehiscence. There were 20 patients who underwent limb volume measurement and completed a 19-item lymphedema symptom assessment questionnaire preoperatively and 3 months postoperatively. A multivariate analysis was performed to evaluate potential risk factors for complications. A microcosting analysis was also performed to evaluate the direct costs associated with wound complications. RESULTS: The 30-day wound complications were noted in 77.4% of patients. A BMI ≥ 30 (n = 28) increased the risk for wound complications (odds ratio [OR] = 11.4, 95% confidence interval [95%CI] 1.6-78.5, P = .01), while advanced nodal disease approached significance (OR = 9.0, 95%CI: 0.79-103.1, P = .08). Other risk factors, including diabetes, smoking, and the addition of a deep pelvic (iliac/obturator) dissection to ILND, were not significant. Of 20 patients, 9 (45%) developed limb volume change (LVC) ≥5% at 3 months, with associated mean symptom scores of 6.1 versus 4.6 for those without LVC. Costs for patients with wound complications were significantly higher than for those without wound complications. CONCLUSIONS: Postoperative wound complications and early onset lymphedema occur frequently following ILND for melanoma. Obesity is an adverse risk factor for 30-day wound complications that can significantly increase postoperative costs, as is likely the case for advanced disease. Risk reduction practices and novel treatment approaches are needed to reduce postoperative morbidity.

Fibrin sealant does not decrease seroma output or time to drain removal following inguino-femoral lymph node dissection in melanoma patients: a randomized controlled trial (NCT00506311).

BACKGROUND: This study assessed the impact of closed suction drains and evaluated whether the intraoperative use of a fibrin sealant decreased time to drain removal and wound complications in melanoma patients undergoing inguino-femoral lymph node dissection. METHODS: A pilot study (n = 18) assessed the impact of a closed suction drain following inguino-femoral lymph node dissection. A single-institution, prospective trial was then performed in which patients were randomized to a group that received intraoperative application of a fibrin sealant following inguino-femoral lymph node dissection or to a control group that did not receive sealant. RESULTS: The majority of the patients enrolled felt the drains caused moderate or severe discomfort and difficulties with activities of daily living. Thirty patients were then randomized; the median time to drain removal in the control group (n = 14) was 30 days (range, 13-74) compared to 29 days (range, 11-45) in the fibrin sealant group (n = 16; P = 0.6). Major and minor complications were similar in the two groups. CONCLUSION: Postoperative closed suction drains were associated with major patient inconvenience. Applying a fibrin sealant at the time of inguino-femoral lymph node dissection in melanoma patients did not reduce the time to drain removal or postoperative morbidity. Alternative strategies are needed.
