Surgical and oncological outcomes after ultrasound-guided robotic liver resections for malignant tumor. Analysis of a prospective database

摘要

Aim Robotic surgery is thought to have a role in widening the application of minimally invasive liver surgery. Nonetheless, data concerning surgical results for liver malignancies are presently still lacking. We aimed to evaluate the surgical and oncological outcomes of ultrasound guided robotic liver resections for hepatic malignancies. Methods All consecutive patients who received robotic resection of primary and secondary liver malignancies from September 2008 to January 2017 were analyzed. The same surgical team performed all procedures following the principle of parenchymal-sparing surgery. Results From a total of 51 patients, 13 patients (25%) underwent major and 38 (75%) minor hepatectomy. No mortality occurred. Two procedures were converted to open surgery. Five patients experienced major complications, with a reintervention rate of 6%. Median hospital stay was 5 days. Conclusions Robotic surgery is a safe and feasible procedure for liver resection even when dealing with malignancies. Our data show that robotic surgery can be considered a valid option to treat patients with liver malignancies in a minimally invasive manner, without compromise the oncological results.
