Summary

Indocyanine green (ICG) fluorescence imaging enhances robot-assisted liver resection by improving tumor visibility and guiding surgical margins. This technique compensates for reduced tactile sensation, aiding surgeons in complex procedures.

Area Of Science

Minimally Invasive Surgery
Surgical Navigation Technologies
Medical Imaging

Context

Laparoscopic liver resection increasingly utilizes intraoperative navigation.
Overlaying ICG fluorescence imaging onto monitors is beneficial in laparoscopic procedures.
Robot-assisted liver resection (RALR) presents unique challenges, including a lack of tactile feedback.

Purpose

To evaluate the utility of Indocyanine Green (ICG) fluorescence navigation in robot-assisted liver resection (RALR).
To assess ICG fluorescence for tumor identification and margin assessment in RALR.
To determine if ICG fluorescence can mitigate the sensory limitations of RALR.

Summary

ICG fluorescence imaging was employed in all RALR cases within the department.
The technique proved effective for identifying tumors and ensuring adequate surgical margins.
ICG fluorescence imaging successfully compensated for the diminished tactile sensation inherent in RALR.

Impact

Enhances precision in tumor resection during RALR.
Improves surgeon confidence and potentially patient outcomes in minimally invasive liver surgery.
Establishes ICG fluorescence as a valuable tool for overcoming RALR's sensory deficits.
