Trends in incidence and clinical feature of hypertriglyceridemic acute pancreatitis: clinical review of 20 years / 中华胰腺病杂志

ABSTRACT

Objective To retrospectively investigate the clinical features and incidence trends of hypertriglyceridemic acute pancreatitis (HLAP) in Guangzhou First People's Hospital for 20 years.Methods The medical records of 1 362 patients,who were admitted to Guangzhou First People's Hospital with acute pancreatitis during January 1991 to December 2010,were reviewed and 99 patients met the HLAP criterion.These patients were divided into four groups according to years (1991 ～ 1995,1996 ～2000,2001 ～2005,and 2006 ～2010).The incidence and clinical features were compared among the 4 groups.Results Among the 99 patients,there were 61 males and 38 females,the mean age was (44 ± 12) years old,and young male was predominant in HLAP.HLAP accounted for 7.3％ of all AP patients,and the incidence was increased 1.5 times during the 20 years period (5.4％,5.7％,6.7％,and 8.3％ respectively).The serum amylase level was (513.3 ±462.7) mmol/L,TG level was (12.7 ± 7.0) mmol/L,Ranson score was (1.2 ± 1.1),CTSI score was 2.2 ± 1.1,incidence of SIRS was 36.4％,and the incidence of MODS was 18.2％,and the incidence of pancreatic pseudocyst was 5.1％,but the incidence and mortality of SAP was not changed with time.The incidence and mortality of SAP of HLAP were significantly higher than those of acute biliary pancreatitis (20.2％ vs 8.5％,6.1％ vs 2.8％).The rate of blood purification increased from 0 to 10.7％,and the hospital stay was decreased from 26 d to 14 d,and the difference between the two groups was statistically significant (P ＜ 0.05).Conclusions Incidence of HLAP is increased gradually,with a trend towards more severe disease,but the prognosis is improved.
