Liver resection in octogenarians.

BACKGROUND
Liver resections are increasingly being performed safely in elderly patients. There are no present reports of the operative safety of liver resection in octogenarians who represents a rapidly increasing segment of the population. The purpose of this study was to analyse the results of liver resection in octogenarians over a 5 year period within a tertiary referral liver surgery unit.


METHODS
Prospective data collection and analysis of octogenarians having liver resection between 1999 and 2004. Retrospective detailed case note analysis was performed to determine peri-operative mortality and morbidity. Comparison were made to other large series of liver resection in younger patient cohorts. The primary outcome measure was 30 day mortality and secondarily a detailed analysis of post-operative complications was performed.


RESULTS
A total 15 octogenarians (median age 82) were identified from the database. There was 1 peri-operative mortality. The remaining patients were all alive at 1, 3 and 6 month follow-ups with a median follow-up of 18 months. The commonest indication for liver resection was metastatic colorectal cancer (n=1). The median operating time was 142.5 minutes and 67% of patients (n=10) had portal clamping for a median of 21.5 minutes. The median length of hospitalization was 12 days with an ICU stay of 1 day, 27% (n=4) had major surgical complications. A further 20% (n=3) had exacerbations of pre-existing comorbidities.


CONCLUSION
Liver resection can be performed safely in octogenarians within a tertiary referral unit. It has a low mortality and an acceptable level of morbidity in carefully selected octogenarians.
