The estimated annual prevalence of acute pancreatitis (AP) in 2011 was 49.4/100,000, based on a nationwide survey conducted in Japan. The (male/female) sex ratio of the patients was 1.9, with a mean age of 58.5 years for men and 65.3 years for women. In men, the most common cause was alcohol consumption (46.2 %), followed by biliary (19.7 %) and idiopathic (13.4 %) causes. Conversely, in women, biliary (40.3 %) was the most common cause, followed by idiopathic (22.8 %) causes and alcohol consumption (9.9 %). The overall mortality rate of AP was 2.6 %. The mortality rate was 10.1% in patients with severe AP, as classified by the Japanese severity assessment systems. |
