Etiology and age have only a limited influence on the course of acute pancreatitis

In a retrospective study of 602 patients with a first attack of acute pancreatitis, it was investigated whether the etiology of the disease and age of the patient are negative factors. There was no significant difference concerning hospital stay, respiratory and renal insufficiency, indication for surgery, or mortality rate among the different etiological groups. However, pancreatic pseudocysts developed significantly more frequently in alcoholics than in patients with other etiologies (p < 0.001 to p = 0.007). There was also no difference concerning hospital stay and respiratory insufficiency among the age groups. The increased incidence of renal insufficiency probably is related to physiological alteration with age, but the indication for dialysis did not increase. Pancreatic pseudocysts were more frequent in patients between 31 and 40 years of age, which was also the peak age group of alcoholics. Indication for surgery was the same for all age subgroups. The increase in mortality rate with age was weakly significant (p = 0.049). For the etiological subgroups, an increase in mortality with age was found only for biliary pancreatitis patients (p = 0.003). It is concluded that etiology and age of the patient have only limited influences on the course of acute pancreatitis.
