Abstract

Background: The ICG fluorescence properties are progressively gaining momentum in the HPB surgery. However, the exact impact of ICG application on surgical outcomes is yet to be established. Methods: Twenty-five patients who underwent ICG fluorescence-guided robotic liver resection were case-matched in a 1:1 ratio to a cohort who underwent standard robotic liver resection. Results: In the ICG group, six additional lesions not diagnosed by preoperative workup and intraoperative ultrasound were identified and resected. Four of the lesions were proved to be malignant. Despite the similar operative time (288 vs. 272 min, p = 0.778), the risk of postoperative bile leakage (0% vs. 12%, p = 0.023), R1 resection (0% vs. 16%, p = 0.019) and readmission (p = 0.023) was reduced in the ICG group compared with the no-ICG group. Conclusions: The ICG fluorescence is a real-time navigation tool which enables surgeons to enhance visualization of anatomical structures and overcome the disadvantages of minimally invasive liver resection. The procedure is not time-consuming, and its applications can reduce the postoperative complication rate in robotic liver surgery.
