Summary: Background: Patients with spinal cord injury (SCI) have increased prevalences of gallstones and acute acalculous cholecystitis. A possible explanation for the increased prevalence of gallstone disease in SCI patients is decreased gallbladder motility causing gallbladder stasis, a known risk factor for gallstone disease. We investigated gallbladder function in SCI. Methods: Twenty-five normal control subjects and 50 SCI patients were included in this study. Gallbladder function was measured by technium 99m-labeled imino-diacetic acid analogue (Tc-99m DISIDA) cholescintigraphy and represented by the filling fraction (FF) and the ejection fraction (EF). The SCI patients were assigned to subgroups: old versus young, female versus male, high- versus low-level injury, and long versus short injury duration. Results: Forty-two percent of SCI patients had abnormal FFs and 54% of SCI patients had abnormal EFs. Significantly decreased FF and EF values were found in SCI patients, especially in those who were female and had high-level injuries. Conclusion: With the use of quantitative Tc-99m DISIDA cholescintigraphy, we found that SCI can significantly impair gallbladder function.
