Contemporary practice and short-term outcomes after liver resections in a complete national cohort
- 11 Downloads
Improved outcome after liver resections have been reported in several series, but outcomes from national cohorts are scarce. Our aim was to evaluate nationwide practice and short-term outcomes after liver surgery in a universal healthcare system.
A complete 5-year cohort of all liver resections from the Norwegian Patient Registry (NPR). Short-term outcomes were aggregated length of stay (a-LoS), reoperation and 90-day mortality.
Of 2118 liver resections, 605 (28.6%) were major, median age was 65 years and 1184 (55%) were male. Most common indication was metastatic disease (n = 1554; 73.4%) and primary malignancy (n = 328; 15.3%). Laparoscopy was performed in 513 (33.9%) of minor and 37 (6.1%) of major liver resections and increased over time to 39.1% of minor resections in 2016. Median a-LoS was 12 days for major resections, 8 days for open minor and 3 days for laparoscopic minor resections. Reoperation was reported for 159 (7.4%) and 90-day mortality for 44 (2.1%). Primary malignancy, male gender, elderly patients and major resections were associated with poorer outcome.
In a national cohort, laparoscopy is used for a substantial proportion of minor resections and was associated with reduced a-LoS. Risk factors for reoperation and mortality were male gender, increased age and major resection for primary malignancy.

Compliance with ethical standards
Centre of Clinical Documentation and Evaluation (SKDE) holds a concession from the Norwegian Data Protection Authority to access data from the Norwegian Patient Registry (NPR) for patients treated at Norwegian hospitals in the period 1 January 2012 to 31 December 2016. The Norwegian Data Inspectorate licenced the data registry at SKDE (ref. 15/00271–2/CGN and 16/00289–2/CGN). Further ethical approval was not required according to Norwegian law.
Data from the Norwegian Patient Register has been used in this publication. The interpretation and reporting of these data are the sole responsibility of the authors, and no endorsement by the Norwegian Patient Register is intended nor should be inferred.
