Reducing morbidity with surgical adhesives following inguinal lymph node dissections for the treatment of malignant skin tumors

Background: Inguinal lymph node dissection (ILND) is associated with a high rate of morbidity. To evaluate the clinical benefit of surgical adhesives to reduce complications in patients undergoing ILND, we compared the use of TissuGlu(®) Surgical Adhesive and ARTISS(®) fibrin sealant with a control population. Material and methods: We conducted a retrospective analysis of patients undergoing ILND for metastatic malignant skin tumors at one hospital, Fachklinik Hornheide (Münster, Germany), from January 2011 through September 2013, assessing 137 patients with a total of 142 procedures. Results: Complications occurred in 22/60 procedures in the TissuGlu group (TG), in 8/17 in the ARTISS group (AG), and in 29/65 in the control group (CG). Prolonged drainage and seroma were recorded in 16 (26.7%), four (23.5%), and 26 (40%) respectively (non-significant). TG showed less extended drainage vs. CG (p=0.082). Mean daily drain volumes were significantly lower in AG vs. CG (p=0.000). With regard to wound infection, there was a 15% reduction in TG and 74% increase in AG group. Revision surgery was reduced by 36% in TG and increased by 54% in AG. Mean daily drain volumes were significantly lower in AG vs. CG (p=0.000). Mean total post-operative drain volume was lower in TG and AG vs. CG (p<0.001 among groups, CG vs. TG p<0.001, CG vs. AG p<0.001). The mean body mass index (BMI) was significantly higher in patients with complications, 29.4±5.8 vs. 25.3±4.1 (p=0.000). Conclusion: The use of TissuGlu in our ILND patients was associated with a reduction in post-operative wound related complications and the need for revision surgeries compared to the control group. Daily drainage was significantly lower within the first 7 post-operative days with the use of ARTISS, but the benefit was lost due to the higher occurrence of wound infection and revision surgery. BMI above 29 is a risk factor for complications following ILND. (Level of evidence: level IV, retrospective case study)
