[The noninvasive investigation of duodenogastric reflux before and after pyloroplasty (author's transl)].
In five anesthetized cats the excretion of Tc-99m-DAIDA into the gallbladder and the small bowel and the d.g. reflux were visualized by a gamma camera and analyzed by a digital computer. A d.g. reflux index was calculated following stimulation of the gallbladder by ceruletide and test meals, before and after a Heineke-Mikulicz pyloroplasty. It could be demonstrated that tracing of bile with TC-99m-DAIDA can be used as a noninvasive method for the evaluation of the d.g. reflux. Gastric intubation increases the d.g. reflux rate. Ceruletide is a much more effective choleretic agent than test meals. Despite a wide pyloroplasty neither an augmented d.g. reflux nor gastritis was seen, probably due to the preserved antral innervation.
