OBJECTIVE To study the efficacy of a new laparoscopic varicocelectomy technique using indocyanine green (ICG) angiography.
METHODS Laparoendoscopic single-site (LESS) varicocelectomy using ICG angiography was performed in a single institution on 11 patients with a grade 2 or 3 varicocele. Adult men (N = 9, 82%) who were apparently infertile and had a varicocele, as well as prepubertal boys (N = 2, 18%) with testicular growth retardation, underwent a LESS varicocelectomy using ICG angiography. After the separation of testicular veins, arteries, and lymphatics, ICG was injected intravenously, and arterial and venous blood flows were observed by ICG fluorescence. Spermatic veins were cauterized by bipolar forceps and cut. The spermatic artery and lymphatics were preserved.
RESULTS The mean time to the arterial phase (AP) from the ICG injection was 34.9 seconds and the mean time to the venous phase was 58.3 seconds. The mean interval from the arterial phase to the venous phase was 23.3 seconds, and in all cases, this time interval facilitated the identification of arteries and veins. The rates of residual varicocele 3 and 6 months after surgery were 9.1% and 0%, respectively. Serious postoperative complications were not observed nor were adverse events induced by ICG.
CONCLUSION ICG angiography appears to be safe and appears to facilitate the detection of artery and veins during LESS varicocelectomy. Continuing investigations of efficacy are required of this new and promising procedure in a larger number of patients. (C) 2017 Elsevier Inc.
