ABSTRACT
OBJECTIVES:
To determine the type and frequency of pancreatic lesions detected by magnetic resonance cholangiopancreatography (MRCP) in subjects with asymptomatic pancreatic hyperenzymemia and to assess for a possible relationship between these lesions and the hyperenzymemia.METHODS:
From January 2005 to May 2008, 63 subjects with asymptomatic pancreatic hyperenzymemia were studied by MRCP. In addition, amylase, pancreatic isoamylase, and lipase were determined for 5 consecutive days.RESULTS:
In most subjects (n = 57, 90.5%), MRCP showed a normal pancreas. In the remaining 6 subjects (9.5%), the following alterations were found pancreas divisum in 2, small intrapancreatic cyst in 2, anatomic variant of the Wirsung in 1, and mild dilatation of 3 secondary ducts in 1. In these 6 subjects, hyperenzymemia was highly variable from day to day, with frequent normalizations, as was also true for the 30 subjects with no MRCP alterations in whom diurnal enzyme determinations were made.CONCLUSIONS:
Most of the subjects with asymptomatic pancreatic hyperenzymemia did not have pancreatic lesions detectable by MRCP. In the few subjects in whom a lesion was found, the great variability and the frequent transient normalization of serum enzyme levels tend to exclude a relation between the lesion and the hyperenzymemia.
