Abstract
AIM: To determine methods for detection and confirmation of duodenal-biliary reflux.
METHODS: One hundred and twenty-three patients with a T tube after cholecystectomy and choledochotomy were randomly divided into reflux and non-reflux groups by measuring the amount of radioactivity of 99mTc-DTPA, ICG, amylase, lipidase and pepsinogen II in the bile. The incidence rate for barium in the biliary tract after barium meal examination was recorded to confirm the existence of duodenal-biliary reflux.
RESULTS: The amount of radioactivity of 99mTc-DTPA, ICG, amylase and lipidase in the bile of patients with a T tube after cholecystectomy and choledochotomy was detected to a varying extent. Radioactivity of 99mTc-DTPA provided the most sensitive measure.
CONCLUSION: Establishing a methodology for detection and confirmation of duodenal-biliary reflux has an important role in research into estimating the structure and function of the Oddi sphincter and formation of bile duct pigment stones.
