From the abstract
Anatomic segmentectomy 8 of the liver is among the most technically demanding procedures, primarily because of the deep intraparenchymal location and marked anatomic variability of the segment 8 Glissonean pedicle (G8) and the inherently curved configuration of the intersegmental planes.
Reported results
The operative time was 180 min, with an estimated blood loss of 10 mL. No intraoperative transfusion was required. The Pringle maneuver was applied intermittently for a cumulative duration of 45 min. A 30-mm hepatocellular carcinoma was resected with a clear surgical margin of 11 mm. The postoperative course was uneventful, and the patient was discharged on postoperative day 7.
Authors' conclusions
Robotic anatomic segmentectomy 8 using a cranial HVGA integrated with ICG fluorescence imaging enables precise identification of G8 and accurate navigation along the curved intersegmental planes of S8. This three-element integrated strategy provides an anatomically grounded, reproducible framework for safe and complex robotic anatomic segmentectomy.
