Endoscopy-assisted inguinal lymphadenectomy in vulvar cancer
To explore the feasibility and efficiency of video endoscopic inguinal lymphadenectomy (VEIL) for vulvar cancer.
We evaluated 46 patients with vulvar cancer. Treatment included VEIL using the hypogastric subcutaneous approach (VEIL-H, 17 patients), VEIL with the limb subcutaneous surgical approach (VEIL-L, 8 patients), and open inguinal lymphadenectomy (OIL, 21 patients). All patients underwent radical vulvectomy; we evaluated operative time, the amount of bleeding, SF score, recurrence rate, etc.
The durations of VEIL-H and VEIL-L were 170.79 ± 18.92 and 180.12 ± 17.88 min, respectively, which were longer than that of OIL (100.68 ± 11.37 min; P = 0.028). Bleeding volumes in the VEIL-H and VEIL-L groups were 15.23 ± 2.17 and 17.16 ± 2.35 ml, respectively; there were significantly lower than that of the OIL group (36.68 ± 3.48 ml; P = 0.021). The numbers of unilateral lymph nodes harvested were similar in all groups. The duration of hospitalization in VEIL group was shorter than that of the OIL group. There were less skin and lymphatic complications after VEIL than after OIL. Total SF-36 scores were significantly higher in the VEIL group than that in the OIL group (P = 0.032). There were no statistically significant differences in local recurrence, distant metastasis, and mortality among the three groups.
VEIL for vulvar cancer treatment is effective, with the advantages of short hospitalization stay, less bleeding, and reduced postoperative complications comparing the OIL.
