Introducing minimally invasive inguinal lymph node dissection in a UK tertiary skin cancer service: Initial experience & outcomes

Reducing the incidence of problematic seroma formation and skin necrosis post-lymphadenectomy: Triple action of topical tranexamic acid, negative pressure wound therapy, and prolonged drainage

BACKGROUND

Axillary and inguinal lymph node dissections are commonly associated with complications that often require additional interventions.

METHODS

Patients who underwent axillary or inguinal lymphadenectomy via standard procedures were compared to an intervention cohort of patients who underwent axillary or inguinal lymphadenectomy with the use of topical tranexamic acid (TXA) to the wound cavity, a PICO (Smith&Nephew UK) closed-incision negative pressure dressing, and discharged early with a drain in-situ.

RESULTS

Seventy-six patients in the control group (mean age 65.8 years, mean BMI 28.4 kg/m2) underwent open lymphadenectomy without topical TXA and a simple dressing. Seventy-eight patients were included in the intervention group (mean age 67.1 years, mean BMI 28.5 kg/m2). Patients in the intervention group had an inpatient stay of mean 5.6 days fewer than those in the control group (CI 3.09-5.31; p < .0001), an estimated saving to the healthcare trust of £ 3046.40 (US$3723.61) per patient in "bed days." They had longer drain duration (mean 15 days vs. 8.3 days); however, they had a statistically significant lower risk of seroma formation requiring drainage (6.4% vs. 21%; p = .009), and skin necrosis (0% vs. 6.6%; p = .027). They also had a lower risk of infection (17% vs. 29%), wound dehiscence (15% vs. 25%), and readmission (7.7% vs. 14%), although they were not statistically significant. Patients in the control group were more likely to receive antibiotics as inpatients (51% vs. 7.7%; p < .00001) and on discharge (24% vs. 5%; p < .0011) than those in the intervention group.

CONCLUSIONS

Topical TXA, PICO dressing, and early discharge with a drain following lymphadenectomy results in a reduced rate of complications.

Starting a minimally invasive inguinal lymphadenectomy program: Initial learning experience and outcomes

BACKGROUND

There is promising data on minimally invasive inguinal lymphadenectomy indicating decreased wound complications compared with the standard open approach. We examined our institutional experience with starting a minimally invasive inguinal lymphadenectomy program.

METHODS

This is a retrospective case series of consecutive patients undergoing videoscopic minimally invasive inguinal lymphadenectomy from August 2017 to March 2022 by a single surgeon. Patients meeting criteria for inguinal lymphadenectomy were considered for minimally invasive inguinal lymphadenectomy unless there was skin involvement by tumor or bulky disease. Data collected included patient characteristics, primary cancer, surgery, and postoperative complications.

RESULTS

There were 26 patients included. The mean age was 60.6 ± 16.2 years. Most patients were female (n = 17, 65.4%), and the primary diagnosis was melanoma (n = 21, 19.2%). In 6 cases (23.1%), minimally invasive inguinal lymphadenectomy was combined with deep pelvic node dissection, but most patients did not have a concurrent procedure (n = 15, 57.7%). The median operative time was 119.0 minutes (range, 89.0-160.0), or 130.5 minutes (range, 89.0-345.0) when including concurrent procedures. The mean number of nodes retrieved was 9.8 ± 3.7, with a positive node identified in 19 patients (73.1%) during minimally invasive inguinal lymphadenectomy. There were 12 (46.2%) patients experiencing at least one postoperative complication within 30 days of surgery, the most common being infection (n = 4, 15.4%). One patient required reoperation for infected hematoma washout. Postoperative intervention for seroma was undertaken in 3 patients (11.5%).

CONCLUSION

Minimally invasive inguinal lymphadenectomy is a safe approach to inguinal lymph node dissection, in terms of node retrieval and postoperative complications, and can feasibly be adopted into practice with minimal learning curve.
