Clinical characteristics analysis of 2625 acute pancreatitis in Jiangxi Province / 中华消化杂志

ABSTRACT

Objective To analyze the clinical characteristics of patients with acute pancreatitis (AP) in Jiangxi Province.Methods From 2007 to 2012,the data of 2 625 hospitalized patients diagnosed as AP were retrospectively analyzed.The changes of composition in gender,age and etiology during 2007-2009 time period and 2010-2012 time period were compared.Mann Whitney U test was performed for non-normal distribution measurement data analysis and x2 test was for count data analysis.Results Among the 2 625 patients with AP,from 2007 to 2009 there were 1 028 cases and 1 597 cases in the period 2010 to 2012.The ages of the patients in these two period were 50(38,61) and 50 (40,63) years old,respectively.There was statistically significant difference in the age distribution between these two period (U=783 635.5,P＜0.05).Biliary factor was the most common cause of AP in the two time period 2007 to 2009 and 2010 to 2012,which accounted for 55.9％ (575/1 028) and 62.9％ (1 005/1 597),respectively,and the difference was statistically significant (x2=12.778,P＜ 0.01).Alcoholic AP accounted for 1.9％ (19/1 028) and 7.3％ (117/1 597),respectively,hyperlipidemic AP were 14.0％ (144/1 028) and 17.7％ (283/1 597),and idiopathic AP were 22.0％ (226/1 028) and 5.9％ (94/1 597),all the differences were statistically significant (x2 =38.204,6.330 and 151.416,all P＜0.05).In male patients,biliary AP accounted for 52.4％ (732/1 398),which was lower than that of female patients (69.1％,848/1 227),and the difference was statistically significant (x2 ＝76.524,P＜0.01).Alcoholic AP and hyperlipidemic AP accounted for 9.0％ (126/1 398) and 21.4％ (299/1 398) in male patients,which were significantly higher than those of female patients (0.8％,10/1 227; 10.4％,128/1 227),and the differences were statistically significant (x2 89.396 and 57.585,both P＜0.01).Biliary AP accounted for 79.9％ (631/790) in elderly group,which was higher than that of non elderly group (51.7％,949/1 835),and the difference was statistically significant (x2＝182.720,P＜0.01).In elderly group hyperlipidemic AP and alcoholic AP accounted for 2.5％ (20/790) and 1.3％ (10/790),which were significantly lower than those of non-elderly group (22.2％,407/1 835; 6.9％,126/1 835),and the differences were statistically significant (x2 =156.524 and 35.262,both P＜0.01).Conclusions The middle-aged and elderly people are the vulnerable population of AP.Biliary factor is the most common cause of AP,especially in the female and elderly.The proportions of hyperlipidemic AP and alcoholic AP both significantly increase,in the male higher than that of the female and in the non-elderly higher than that of the elderly.The proportion of idiopathic AP significantly decreases.
