Robot-assisted liver resections in locally advanced intrahepatic cholangiocarcinoma

Abstract

Aim. To evaluate the immediate results of robot-assisted liver resections in locally advanced intrahepatic cholangiocarcinoma. Materials and methods. The research methodology involved the analysis of intraoperative and direct results of robotassisted liver resections from 2015 to June 2023. Results. Total of 89 patients with intrahepatic cholangiocarcinoma underwent surgery. Open liver resection was performed in 59 cases (66.3%), laparoscopic resection – in 22 cases (24.7%), robot-assisted resection – in 8 cases (8.9%). The share of massive liver resections accounted for 83%. The average duration of robot-assisted liver resection amounted to 545 (327–640) minutes, blood loss volume – 300 (100–750) ml, number of resected lymph nodes – 7 (5–11), resection margin width – 6 (5–14) mm. All patients underwent extensive resection with elements of vascular or biliary resection. Severe complications developed only in half of the patients. No deaths or liver failures were reported. The average duration of hospital stay after surgery amounted to 11 (6–15) days. Conclusion. Robot-assisted liver resections expand the indications for minimally invasive surgeries in intrahepatic cholangiocarcinoma due to patients with locally advanced forms. Satisfactory immediate results justify further accumulation and evaluation of the experience of such interventions.
