Abstract

Background: In April 2018, a dedicated hepatobiliary unit was established in a tertiary hospital in North Queensland. Changes included the employment of a hepatobiliary-trained surgeon, centralized referrals, and formalized multidisciplinary team meetings. This study aimed to evaluate the impact of establishing a hepatobiliary unit on outcomes after liver resection, in a regional centre where such procedures were previously performed by non-specialist general surgeons.

Methods: Adult patients who underwent elective liver resection in Townsville from 2013 to 2020 were included in the study. Outcomes after liver resection were collected across two study periods - before and after the hepatobiliary unit was established. The primary end points were a before and after comparison of the 90-day morbidity and mortality and the R1 margin rates.

Results: Across the two study periods, 76 and 77 patients, respectively, underwent liver resection. Rates of R1 resection, 90-day mortality and major complications were not significantly different between the two study periods. Primary tumours (14.5% before versus 50.6% after) and cirrhosis (1.3% before versus 14.3% after) were significantly higher in the latter period, as was the median length of stay (4 days before versus 6 days after). Annual surgical volume increased by 75% in the period after 2018 compared to the 5 years preceding it.

Conclusion: Establishing a centralized hepatobiliary unit in a tertiary regional centre resulted in increased surgical volume and case complexity, with no change in early outcomes after liver resection. Overall, this dedicated unit improved the accessibility of a subspecialty surgical service in regional Australia.
