Bile diversion from the duodenum: its effect on gastric and pancreatic function.
Scandinavian Journal of Gastroenterology. Supplement
|January 1, 1984
Summary
Bile diversion in dogs increased stomach acid and gastrin levels, while decreasing pancreatic trypsin and cholecystokinin (CCK). This may explain increased peptic ulcers after the procedure.
Area of Science:
- Gastroenterology
- Digestive Physiology
Background:
- Bile diversion from the duodenum can impact digestive processes.
- Understanding these effects is crucial for surgical outcomes.
Purpose of the Study:
- To investigate the physiological effects of diverting bile from the duodenum.
- To assess the impact on gastric acid secretion, hormone levels, and pancreatic function.
Main Methods:
- Utilized a double-marker perfusion technique in four dogs.
- Monitored gastric acid secretion, serum gastrin, pancreatic trypsin output, and cholecystokinin (CCK) levels.
- Analyzed gastric emptying and duodenal pH during liquid meal digestion.
Main Results:
- Bile diversion significantly increased gastric acid secretion (0.8 to 1.48 mmol H+/min) and serum gastrin levels.
- Pancreatic trypsin secretion decreased (3.91 to 2.66 IU/min) and CCK levels were lower post-feeding.
- No significant change in gastric emptying rate, but lower duodenal pH observed.
Conclusions:
- Bile diversion leads to acid hypersecretion and pancreatic inhibition.
- These physiological changes may contribute to the increased incidence of peptic ulcers.
- Surgical consideration requires anticipation of these digestive consequences.
