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.
