Background
The frequency, costs and outcome of pancreatic resection (both pancreaticoduodenectomy and distal pancreatectomy) were reviewed in our own institution and correlated with regional population growth as well as national resection rates and locations.
Methods
Demographic, pathological and outcome data on pancreaticoduodenectomy and distal pancreatectomy were obtained from a prospectively maintained database for the years 2005–2009 and 2010–2014. During this period, the catchment population grew from 460 000 to 567 000. Costing information was obtained from the hospital-independent costing and coding committee, and the locations and rates of pancreatic resection were obtained by interrogating the national minimum dataset.
Results
A total of 41 pancreatectomies (29 pancreaticoduodenectomy, 12 distal pancreatectomy) were performed between 2005 and 2009, increasing to 84 pancreatectomies (55 pancreaticoduodenectomies, 27 distal pancreatectomies and two total pancreatectomies) between 2010 and 2014. This constituted one sixth of the national volume of pancreatic resections. There was no difference in patient demographics or indications for resection between the two time periods; however, portal vein resection was used more frequently in the second period. Margin positivity rate decreased (7 of 41 versus 8 of 84) and lymph node harvest increased (median 8 nodes versus median 15 nodes) between the two time periods. Overall 30-day mortality was 1.6%.
Conclusion
In New Zealand, regional rates of pancreatic resection reflect regional population demands, and institutional growth is driven by local population requirements. Institutional growth can be achieved with the maintenance of internationally accepted outcomes and quality indicators.
