Introduction: Robotic surgery is widely diffused in the surgical field and is becoming increasingly prevalent, however several aspects need more detailed assessment. One of them concerns the role of robotic liver surgery for lesions in contact with major vascular (CMV) pedicles. The aim of our study is to evaluate and compare intra and post operative outcomes in patients undergoing robotic liver resections between lesions in contact or free from major vessels.
Methods: A multicentric retrospective study was performed including 1030 patients who underwent robotic liver resection. Patients were divided into two groups according to vascular contact. Intra and post-operative outcomes were compared between the groups before and after Propensity Score Matching.
Results: After propensity score matching 889 patients were included in the study. Among these lesions, 595 were not in contact with major vessels (NCMV) and 294 were in contact with major vessels (CMV). Use of Pringle Manoeuvre was more associated with CMV resections (49.8 % vs 31.2 %, p = 0,0001). No differences in terms of operative time, conversion rate, morbidity and type of complications were observed after PSM.
Conclusion: The presents study shows how robotic surgery is a valid and safe technique also for resection of tumors close to vascular pedicles.
