Abstract
In 37 cases of chronic pancreatitis, endoscopic retrograde pancrentogram (E. P. G) was studied in relation to duration of the symptoms. The association of pancreatolithiasis, diabetes mellitus and liver damage was also cosid-ered. Most of E . P . G . findings widely accepted as diagnostil of this disease, e.g. "Irregu-lar branches" "Rosary" and "Obstructive" changes of the main duct didn't change all though the clinical caurce. They may, therefore, indicate the final stage of the changes. On the other hand, "Simple dilation" appeared in the very, early stage of the disease, and "Stens-sis" was sean in the relatively early plase. These two findings changed to other stable E . P. G. Patterns with lapse of time staging of this disease by E. P. G. Findings may be possible, but requires further investigation.
