Background: Minimally invasive surgery is increasingly preferable to open due to reduced recovery time and peri-operative benefits. However, long-term outcomes and disease-free survival data is sparse. Prior to 2017 all hepatocellular carcinoma (HCC) resections in St. Vincent’s hospital were open, however by 2020 the majority of the cases were managed robotically. This study aims to assess disease-free survival following robotic versus laparoscopic or open resections of HCC.

Methods: A retrospective analysis was performed on all patients who underwent resections for HCC in St. Vincent’s Hospital, Dublin from 2012–2022. Data were collected using electronic patient records and clinic letters to ascertain overall rates of recurrence, further treatments and survival. The categorical data were analysed using chi-squared tests.

Results: A total of 106 patients underwent resections of HCC in St. Vincent’s Hospital between 2012–2022. In total 62% of the cases underwent open resections, 24.5% had laparoscopic resection and 13.5% had robotic resections. At time of writing, 53 participants (50%) were still alive with a 5-year overall survival of 26.9% in the laparoscopic group as compared to 19.7% in the open group (P=0.75). Median survival was 2 years in the robotic cohort (2020–2022), 4 years for laparoscopic group (2017–2021) and 3 years for the open resection group (2012–2022). Recurrence of HCC occurred in 64 participants: 71.4% in the robotic resection cohort compared to 61.5% and 57.6% in the laparoscopic and open resection cohorts respectively which was not statistically different.

Conclusions: Robotic resections are the latest treatment for HCC, conferring significant short-term benefits for the patient, but based on this data require ongoing research to demonstrate a beneficial effect in terms of survival and recurrence. Further analysis of the criteria for robotic resections as well as time to recurrence would help to further indicate whether this method results in superior outcomes for patients.
