Background:
Caudate and posterosuperior hepatectomy are technically challenging resections, especially in a minimally invasive approach. We aimed to analyze the outcomes of isolated caudate resection (ICR), en-bloc caudate resection with right/left hepatic lobectomy (ECR), and posterosuperior segment resection (PSR) using our institutional database.
Methods:
Following IRB approval, we prospectively followed 500 consecutive patients between 2013 and 2023 who underwent robotic hepatectomy. Posterosuperior segments include segment 4 A, 7, and 8. The data are presented as median (mean ± standard deviation).
Results:
Of the 500 patients included in this study, 19 (4 %) underwent ICR, 65 (13 %) underwent ECR, and 131 (26 %) patients underwent PSR. ECR was associated with significantly longer operative time, increased EBL, and longer LOS when compared with those of ICR and PSR. The patients who underwent ICR had the shortest operation duration, lowest EBL, and shortest LOS compared to ECR and PSR.
Conclusions:
Robotic resection of liver tumors located in difficult segments is safe and feasible with excellent clinical and oncological outcomes. With appropriate expertise, a minimally invasive approach to those operations should not be avoided.
