Day-to-Day Variations of Serum Pancreatic Enzymes in Benign Pancreatic Hyperenzymemia

Background & Aims: Benign pancreatic hyperenzymemia is a newly identified syndrome that is characterized by a chronic increase of serum pancreatic enzymes in the absence of pancreatic disease. When checked at intervals of months or years, the enzyme levels show considerable variation from one test to another, and enzyme normalization is sometimes seen. The purpose of this study was to determine whether these variations can occur on a day-to-day...
