 note = {Background and Objectives: The gallbladder (GB) function in bed-ridden elderly patients whose lives depend on passive tube feeding was evaluated using ultrasonogrphy (US). Patients and Methods: Twenty-eight bed-ridden patients and 89 controls were studied by US. GB volume changes in response to oral meal ingestion were assessed in15 of 28 patients and 6 of 89 controls. The ultrasonographic images were obtained immediately before the ingestion of fatty meal, and 10, 20, 30, 45 and 60 minutes after the meal using the ellipsoid method. The resting volume, residual volume and the empting times were determined and the ejection fractions were calculated. Results and Conclusions: The prevalence of GB stones in the patients was significantly higher than in the controls (35.7 vs. 16.85 %, P<__0.05). The empting time was also significantly longer (p=0.027) in the patients than in the controls because the contractions were slower in the patients than in the controls. There were no differences in the resting volume, residual volume, each volume of time course and the ejection fractions between both groups. We therefore conclude that the slower GB contraction and the higher prevalence of GB stone formation in the bed-ridden elderly patients might be due to a dysfunction of central nervous system., 論文},
