Intubation of the pancreatic duct in the human.

Summary A technique is described for intubating the duct of Wirung in the human during the operative procedure of transduodenal sphincterotomy. Through this tube the pancreatic duct can be drained and also visualized roentgenographically. Quantitative studies of the composition of the pancreatic juice under various conditions can be carried out at will.

Bilirubin Resorption in Obstructive Jaundice

Summary Bilirubin did not appear in the blood or thoracic duct lymph when the intrabiliary pressure was lower than the secretory pressure of the liver. Obstruction of the common duct by raising the intrabiliary pressure above the secretory pressure of the liver resulted in bilirubinemia of approximately constant level, and in the appearance of bilirubin in the lymph in concentrations which increased as the intrabiliary pressure was increased.

Special tubes for total bile and pancreatic juice collection in the human.

Summary Special tubes for measuring total output of bile and pancreatic juice in man under physiological conditions, are described. Bile secreation from normal livers varied between 1000 and 2000 ml; pancreatic juice from normal pancreas varied between 1500 and 4000 ml.
