To summarize the experience of precision liver resection by da Vinci Xi robot combined with indocyanine green fluorescence localization for liver tumor.

The clinical data of 20 patients with liver tumor resection by indocyanine green fluorescence localization combined with da Vinci Xi robot from Jan. to May 2021 were retrospectively analyzed.

All 20 patients underwent liver tumor resection with the da Vinci Xi robot without intermediate open abdomen, with an operative time of 85 min(70-105 min), and intraoperative bleeding of 110 ml(50-200 ml). Postoperative hospital stay 7 d(5-9 d). The patients recovered well from postoperative liver function, and none of them had complications such as bleeding or bile leakage. The postoperative pathological results were: 10 cases of hepatocellular cancer, 1 case of hepatocellular heterogeneous hyperplasia and bile duct heterogeneous hyperplasia, 6 cases of bile duct cell carcinoma, 1 case of cirrhosis with inflammatory changes in the liver, and 2 cases of adenocarcinoma(gastrointestinal metastasis). 20 patients were resected with R0 and discharged with good healing.

Based on the skillful completion of laparoscopic liver tumor resection, it is safe and feasible to carry out accurate liver resection with indocyanine green fluorescence localization combined with da Vinci Xi robotic surgical system, which has high clinical value and promotion significance.
