Introduction:
Laparoendoscopic single-site inguinal lymphadenectomy (LESS-IL), a minimally invasive technique, has been reported in patients with vulvar or vaginal cancer regarding its safety and feasibility. However, the long-term outcomes, especially oncologic outcomes, are still lacking. We aimed to evaluate the long-term outcomes of LESS-IL to confirm its safety further.
Patients And Methods:
Data were prospectively collected from patients with vulvar or vaginal cancer who underwent LESS-IL at our institution between July 2018 and June 2021. The patients were followed up for at least 12 months. All procedures were performed according to treatment standards. Short- and long-term complications and oncologic outcomes were analysed.
Results:
A total of 16 patients undergoing 28 LESS-IL procedures were identified, amongst whom 4 underwent unilateral LESS-IL. The median numbers of excised groin lymph nodes were 9.0 (6.5-11.8) and 10.5 (8.3-12.0) in each left and right groin, respectively. Short-term complications occurred in 4 (25%) patients, including 18.7% lymphocele and 6.3% wound infection. Long-term complications regarding lower-limb lymphoedema appeared in 6 (37.5%) patients. Most short- and long-term complications were Clavien-Dindo 1 or 2, accounting for 90% of all post-operative issues. After a median follow-up of 27 (21.3-35.8) months, only 1 (6.3%) patient had isolated inguinal recurrence at 13 months postoperatively. No local or distant recurrence occurred.
Conclusion:
Our results suggest that LESS-IL is associated with little incidence of complications and promising oncologic outcomes, further demonstrating the safety and feasibility of the LESS-IL technique in patients requiring IL.
