Robot-assisted modified radical hysterectomy with removal of lymphatic vessel using indocyanine green: A new method.

BACKGROUND: The sentinel lymph node (SLN) procedures using indocyanine green (ICG) have recently been performed worldwide. The aim of this study was to emphasise the safety of robot-assisted modified radical hysterectomy (RAMRH) with removal of the lymphatic vessels (RLV) using ICG in endometrial cancer according to a single surgeon's experience. METHODS: Robot-assisted modified radical hysterectomy with RLV using ICG was performed in patients with endometrial cancer. We compared 34 cases of RAMRH with RLV, with 54 patients without RLV. RESULTS: The median (interquartile range) time for the procedure did not differ between the RAMRH with and without RLV groups (88 [80-114] vs. 88 [79-104] min, p = 0.7). The success rate of RLV was 100% when SLNs were detected. CONCLUSION: Robot-assisted modified radical hysterectomy with RLV using ICG can completely dissect tissue from the uterus, including lymphatic vessels. This procedure using a robotic system with ICG, is simple and does not require additional time.
