[Robotic-Assisted Liver Surgery]

The advantages of minimally invasive liver resections for selected patients are evident. Robots provide new innovations that will influence minimally invasive liver surgery in the future. This article presents our initial experience with this technology in our patient population. Material und Methods: In 14 patients with benign or malignant liver tumours, robotic-assisted liver surgery was performed. Selection criteria were compensated liver function and resection of ≤ 3 liver segments. Chronic liver disease or previous abdominal surgery were no exclusion criteria.Malignant liver tumours were removed in 10 patients (71%) and benign symptomatic liver tumors in 3 patients (21%), respectively, with histopathologically negative margins (R0). One patient suffering from HCC underwent intraoperative ablation. In one case (7%) conversion was necessary. Mean operation time was 296 min (120-458 min); mean estimated blood loss was 319 ± 298 ml. The mean hospital stay of the patients was 8 days (3-17 days). Three patients (21%) suffered from postoperative complications, which were manageable by conservative treatment (Clavien-Dindo I) in 2 cases (14%). One patient (7%) needed endoscopic treatment for postoperative bile leak (Clavien-Dindo III a). No patient died intra- or perioperatively.Robotic-assisted liver surgery is a safe procedure, which provides patients with all benefits of minimally invasive surgery. This highly advanced technology requires surgeons to strive for an increasing level of specialisation, in addition to being well-trained in liver surgery. Hence, a clear definition of the procedures and standardised teaching programs are necessary.
