I have lipase levels that fluctuate from the high end of normal to 20 points over the ref range for the past two years. Normal U/S and CT scan. All other blood work normal, including amalayse. Should I have an EUS or MRCP done? Causing anxiety.

No need to worry. Since your lipase levels are only minimally raised, have been so for two years at least, are associated with a normal serum amylase (and U/S and CAT scan), and are occurring in a patient who is asymptomatic--all argue for nothing serious. It probably represents low grade pancreatitis. Do you drink? Diabetic? Are you on birth control pills? Do you have gluten-related problems? No need for EUS/MRCP.
