Prophylactic incisional negative pressure wound therapy shows promising results in prevention of wound complications following inguinal lymph node dissection for Melanoma: A retrospective case-control series

BACKGROUND

Inguinal lymphadenectomy (ILND) for melanoma is associated with a number of complications including seroma, surgical site infection (SSI), and lymphedema. Incisional negative pressure wound therapy (iNPWT) has shown promising results in preventing postoperative morbidity across a wide variety of surgical procedures, but these results are yet to be investigated in patients undergoing ILND for melanoma.

METHODS

In this study, we reviewed the data of 55 melanoma patients treated with ILND between January 2015 and January 2017 at Odense University Hospital. Patients were followed up until April 2018 for the occurrence of seroma, SSI, and lymphedema. We used prophylactic iNPWT after ILND in 14 patients and compared their morbidity outcomes with the 41 patients receiving standard postoperative wound care in the same period.

RESULTS

The iNPWT intervention significantly reduced seroma compared to the control group (28.6% vs. 90.3%, p < 0.001) and had a trending impact on wound infection (42.9% vs. 65.9%, p = 0.13). The effect was not significant for the prevention of lymphedema (35.7% vs. 51.2%, p = 0.33). Because the iNPWT group had relatively fewer incidences of seroma, SSI, and lymphedema, the iNPWT intervention was more cost-effective than conventional wound care (US$911.2 vs. US$2542.7, p < 0.05).

CONCLUSION

The use of prophylactic iNPWT significantly reduced seroma formation following ILND. These promising results, however, need to be confirmed in a future prospective randomized trial.

Prevention of seroma following inguinal lymph node dissection with prophylactic, incisional, negative-pressure wound therapy (SEROMA trial): study protocol for a randomized controlled trial

Background

Radical inguinal lymphadenectomy (ILND) for metastatic melanoma is associated with a high complication rate. Seroma is often the first postoperative complication, followed by prolonged wound healing sometimes requiring reoperation, infection, multiple outpatient visits and re-hospitalization. Prevention of seroma may, therefore, lead to a reduction in many of the other complications.

Methods/design

The primary aim of this randomized study is to investigate whether fewer patients require treatment for seroma by immediate prophylactic application of incisional, Negative-pressure Wound Therapy (iNPWT) following ILND, compared to standard postoperative treatment. The secondary outcomes include surgical-site infection, dehiscence, hematoma, length of hospitalization, quality of life, safety, long-term assessment of lymphedema and non-inferiority oncological outcome. Data will be registered prospectively at check-ups after 7 and 14 days, 1 and 3 months and 2 years after inguinal lymphadenectomy using case report forms and questionnaires and stored in a secure online database.

Discussion

To our knowledge, this trial is the first randomized study evaluating negative-pressure wound therapy as a prophylactic intervention for complications following melanoma-related ILND. The results from this trial will hopefully determine the efficacy and safety of prophylactic iNPWT treatment in prevention of the clinical relevant short- and long-term postoperative complications following ILND and may provide an evidence base for the an improved postoperative regimen.
