Introduction & objectives
Near-infrared fluorescence imaging with indocyanine green (NIRF/ICG) has emerged as a safe and feasible tool for an enhanced surgical experience. Specifically, the purpose of the current video was to describe the intra-operative use of NIRF/ICG to manage a case of massive lymphorrhea, which occurred after robot-assisted radical prostatectomy (RARP).
Materials and methods
We present the case of a 72-year-old man that underwent Retzius-sparing RARP and extended pelvic lymphadenectomy. After six months, the patient presented to the Emergency Department complaining asthenia, dyspnea and weight loss. CT scan showed severe ascites. The patient underwent a complete clinical evaluation without evidence of pathological findings. Lymphoscintigraphy with 99mTc nanocolloid detected a deficit of lymphatic superficial drainage, with tracer accumulation in the inguinal region and abdomen. A massive lymphorrhea due to lymphatic drainage damage was suspected. Therefore, the patient was submitted to robot-assisted explorative laparoscopy and real-time lymphangiography with ICG. One ml of diluted ICG was injected subcutaneously in the interdigital space and on the sole of each foot, 15 minutes before the surgery. The procedure consisted of lymphatic leakage identification and subsequent double clips application and sealing of the leakage.
Results
The postoperative follow-up period was uneventful. At six months from surgery, a CT scan revealed no residual lymphorrhea. An asymptomatic pelvic lymphocele of approximately 5 cm was detected.
Conclusion
Real-time lymphangiography with ICG allowed accurate intra-operative identification of the lymphatic leakage, which had resulted in massive lymphorrhea. Future studies are warranted to corroborate the role of NIRF/ICG in a such clinical scenario.
