Abstract
BACKGROUND: Repeat laparoscopic liver resection has been used safely and effectively on hepatocellular carcinoma (HCC). However, few studies have been performed on repeat HCC surgery by a da Vinci robot. This study aims to evaluate the outcomes of the patients with repeat HCC treated using a da Vinci robot or laparoscopic system at a single centre. METHODS: All of the patients with repeat HCC treated using a da Vinci robotic or laparoscopic system between April 2017 and April 2020 were included in this retrospective study. RESULTS: There were 24 patients with a mean age of 56 years who underwent da Vinci robotic or laparoscopic surgery for treatment of repeat HCC who were included in this study. The operations lasted 152 ± 25 min and 142 ± 34 min. The average intraoperative blood loss was 284 ± 89 ml and 251 ± 92 ml. The average hospitalisation stay lasted 9 ± 2 days and 9 ± 3 days. The rates at which surgeons switched to open surgery were 9% and 23%. No serious perioperative or post-operative complications were encountered. CONCLUSION: Da Vinci robots can provide a precise dissection of the tissue under a perfect view. It is a technically feasible procedure for less rates at which surgeons switched to open surgery on repeat HCC.
