Patients without a functioning gallbladder experience more duodenogastric bile reflux. Continuous bile flow into the duodenum, without gallbladder regulation, appears to facilitate this reflux, impacting abdominal pain.

Area of Science:

  • Gastroenterology
  • Hepatobiliary System
  • Diagnostic Imaging

Background:

  • Duodenogastric reflux (DGR) of bile is a potential cause of abdominal pain.
  • Gallbladder function plays a role in regulating bile flow into the duodenum.

Purpose of the Study:

  • To investigate the relationship between gallbladder function and DGR in patients with abdominal pain.
  • To determine if absent gallbladder function is associated with increased DGR.

Main Methods:

  • Utilized 99Tcm-EHIDA biliary scintigraphy in 370 patients with abdominal pain during the fasting phase.
  • Evaluated gallbladder function and presence of DGR in 291 patients after excluding common bile duct obstruction.

Main Results:

  • Gallbladder function was present in 169 patients and absent in 122.

Related Experiment Videos

  • DGR was observed in 82 patients.
  • Patients with absent gallbladder function (35%) showed significantly higher rates of DGR compared to those with functioning gallbladders (17%, p < 0.005).

    • Conclusions:

    • Absence of gallbladder function is associated with a higher incidence of duodenogastric bile reflux.
    • Continuous bile flow into the duodenum, unmediated by a functioning gallbladder, may facilitate DGR.
