title: Elevated amylase creatinine clearance ratio and normal serum amylase levels in chronic relapsing pancreatitis after partial pancreatectomy.
abstract: A 29-year-old woman admitted for alcohol detoxification five years after a 90% distal pancreatectomy for chronic pancreatitis had abdominal pain similar to that associated with preoperative pancreatitis. Although her clinical course was consistent with recurrent pancreatitis, the serum amylase level remained normal, but the amylase creatinine clearance ratio became elevated and then returned to normal, paralleling her clinical course. The ACCR may be a useful laboratory method in diagnosing chronic recurrent pancreatitis in patients with decreased functional pancreatic tissue.
