Laparoscopic Resection of Liver Segment 4 with Fluorescence Staining: Feasibility and Efficacy

Researchers successfully performed a laparoscopic anatomic resection of liver segment 4 with middle hepatic vein involvement using indocyanine green fluorescence staining. The operation lasted 263 minutes with a 110-minute Pringle maneuver and 400g of estimated blood loss. The patient was discharged on postoperative day 5 without complications, and histopathology confirmed sigmoid carcinoma and R0 margin. This study demonstrates the feasibility and effectiveness of this technique.
