[Detailed analysis of human pancreatic secretions collected by retrograde catheterization. Parallel or non-parallel excretion of digestive enzymes?].

Pancreatic juices were collected by selective reverse catherism of the chief pancreatic duct in two patients, one free from pancreatic disease and the other having a pancreas cancer. They were analysed in detail especially in order to get information on the mechanism of enzyme excretion. The variations of the digestive enzyme activities (amylase, lipase, trypsin, chymotrypsin, carboxypeptidase A and B) were not superimposable among them or with the fluctuations of the protein concentration in the pancreatic juice samples.

Mucinous cystadenocarcinoma of the pancreas. Ultrasonographic findings in 5 cases.

The ultrasonographic findings in 5 patients (4 males, 1 female, mean age 70 years) presenting with mucinous cystadenocarcinoma of the pancreas are described. The lesion was located in the head and body of the pancreas in 2 cases, in the head alone in 2 others, and in the tail in one. The size ranged from 40 to 85 mm (mean 64 mm).
