[Errors in the diagnosis of chronic pancreatitis].

Basing on the results of long-term studies on 850 patients with different forms of chronic pancreatitis, specific variants of hypo- and hyperdiagnosis of this disease have been considered. Incidence and causes of the nonrecognition of chronic pancreatitis and complicating incretory and excretory pancreatic insufficiency, some secondary clinical pancreatogenic syndromes under out- and in-patient conditions are analysed. Errors in the determination of a type of chronic pancreatitis and the major causes of its development are noted. The practical value of various diagnostic errors in patients with chronic pancreatitis have been specified.
