In order to know clinical significance of endoscopic pancreatocholangiography (EPCG), 278 cases were studied.
The results were as follows:
1) EPCG was successfully performed in 96.9% of 278 cases (including 105 Pancreatography (PG), 37 cholangiography (CG) and 127 pancreatocholangiography). Among themsucceeded rate of PG tried endoscopically was 96.1% and that of CG 73.5%.

3) PG suggested normal pancreas when the diameter of MPD at head was less than 4.0 mm, at body less than 3.0mm, at tail less than 2.0mm; MPD and the branches were smooth; the diameter of the branches was less than 1mm except the chief ones and no cystic dilatation of the branches was found.
4) Chronic pancreatitis was suggested when the diameter of MPD at head was more than 6mm, at body more than 4mm and at tail more than 3mm; the diameter of the branches was more than 1mm except the chief ones; cystie dilatation of the branches was clear or MPD or the branches were of “wavy or beads-like type”.
5) PG findings of pancreatic carcinoma were classfied into four types. The stenosis (III type) or obstruction (IV type) of MPD was found in advanced carcinoma of the pancreas, the rigid outline of MPD (II type) or the interruption and straightening of the branches (I type) were found in relatively early carcinoma of the pancreas.
6) Diameter of the biliary tract became wider as aged.
7) In cases of the stone of the common bile duct, the diameter of the common bile duct was remarkably wide and the stone was shifted upwards by the infused contrast medium and floated in it as a transparent shadow.
8) X-ray features of carcinoma of the common bile duct were the obstruction or the stenosis with rigid outline of the bile duct or the interruption of its outline.
9) X-ray feature of carcinoma of the gallbladder was defect of the fundus of the gall bladder.
10) Generally, severe side effects were not found. After EPCG, serum amylase activity elevated according as how the ductal system was visualized by the contrast medium. The elevation was slight in most instances, but the remarkable stimulation of serum amylase activity occurred in 5 cases out of 6 where even the acinar fillings were obtained.
