To examine long-term survival and causes of death among working-age patients with acute pancreatitis (AP) compared with the normal population.
Few studies have investigated long-term survival after AP and recurrent AP compared with the normal population; moreover, results from those studies are difficult to compare, due to suboptimal control populations and wide variations in follow-up times.
This retrospective, registry-based study included 1644 patients with AP, aged 18 to 64 years, admitted to Oulu University Hospital in 1995 to 2012. Patient data were compared with data from 8220 age- and sex-matched controls that resided in the hospital district area.
