[Biliary secretion. Significance of hypercholeresis from the surgical point of view].

In patients carrying a Kehr tube choledochostomy, the surgeon may observe, but rarely, important hypercholeresis, non-bile-acid dependent, in people with severe advanced chronic hepatic diseases or persistent cholestasis. The amount of bile flowing to the outside can reach two liters and more daily. We have seen this in two patients with compensated hepatic disorders and in another suffering from light cholestasis produced by choledocholithiasis. We have also found the same in three other people with liver and the main biliary extrahepatic tract completely normal. This hypercholeresis is continuous and subject to rapid increases relative to the ingestion of food. Such increases are related to gastrointestinal hormones, specially secretin, which is produced when portions of gastric chyme enters the duodenum.
