Abstract

Background

Open inguinal lymph node dissection (oILND) has high morbidity. Ascending saphenous-sparing video endoscopic ILND (VEILND-AS+) represents a minimally invasive alternative with potential benefits.

Objective

To describe our VEILND-AS+ technique and compare outcomes to oILND.

Design, setting, and participants

This was a retrospective cohort study of penile cancer patients.

Surgical procedure

VEILND-AS+ was performed according to the technique described in the supplementary video.

Measurements

We compared perioperative and pathological outcomes between the two procedures.

Results and limitations

In the study cohort of 206 men we performed 40 VEILND-AS+ and 251 oILND procedures. In comparison to oILND, VEILND-AS+ had a longer operation time (185 vs 120 min; p < 0.01) but a shorter hospital stay (2 vs 4 d; p < 0.01). A median of eight resected lymph nodes with a median of one affected node per groin was observed in both groups. Extranodal extension was found in 30% of cases after VEILND-AS+ and 35% after oILND. In both groups the median drainage time was 13 d. Wound infections were observed in 38% of cases after VEILND-AS+ and 27% after oILND (p = 0.19). Skin necrosis or wound breakdown occurred in 0% and 6% of cases after VEILND-AS+ and oILND (p < 0.01), while lymphoceles were drained in 18% and 7% of cases, respectively(p = 0.03). Following VEILND-AS+ and oILND, 20% and 14% of patients, respectively, were referred to a lymph oedema clinic (p < 0.01).

Conclusions

VEILND-AS+ is a safe procedure and offers shorter hospital stays and possibly a lower risk of skin necrosis and wound breakdown in comparison to oILND. Further improvements in the VEILND-AS+ technique are required to reduce complications associated with dead space and injury to lymphatic vessels.

Patient summary

For patients undergoing surgery on lymph nodes in the groin, a minimally invasive approach instead of open surgery led to discharge 2 days earlier and may have lower rates of severe wound complications.
