ICG mapping of postoperative lymphatic leakage in the groin: a video article and literature review.

BACKGROUND

Inguinofemoral lymphoceles are a common postoperative complication after inguinofemoral lymphadenectomy (LNE) and a challenge for patients as well as physicians. We report here our preliminary experience in the surgical management of a recurrent lymphocele using indocyanine green (ICG) detection, followed by robotic-assisted closure of the lymphatic leaks.

OBJECTIVES

The aim of this article is to illustrate the surgical steps of ICG-assisted detection of inguinal lymphatic leaks and their surgical treatment by means of robot-assisted suturing. Furthermore, the feasibility of the approach will be evaluated.

MATERIALS AND

METHODS

A 59-year-old woman with locally advanced squamous cell carcinoma of the vulva and previous conventional bilateral inguinofemoral LNE presented with symptomatic therapy-resistant lymphoceles in the groin. After a lengthy and frustrating course of standard therapy, she was offered the off-label option surgical treatment with ICG detection and subsequent robot-assisted ligation of the leaks, using the Da Vinci robotic system™.

MAIN OUTCOME MEASURES: Perioperative data, specific aspects of the surgical approach specifics, objective and subjective outcomes of the new approach.

RESULTS

The procedure was performed as planned, with no intraoperative complications or device-related issues. The postoperative course was uneventful, and the patient developed no further lymphoceles.

CONCLUSION

Visualisation of the leakage by ICG combined with minimally invasive robotic-assisted laparoscopy is a promising therapy option. The pictures and videos demonstrate our experience in regard of the safety, feasibility, and usefulness of this procedure. Further studies will be needed, to prove the absolute efficacy of the technique and express a general recommendation in regard of this approach for the treatment of inguinofemoral lymphoceles.
