To ascertain whether aging and/or cholelithiasis can influence oro- cecal transit time (OCTT), we studied a total of 70 subjects, i.e., 10 healthy young adult controls, 22 healthy elderly controls, 18 elderly cholelithiasis patients and 20 elderly subjects with a history of cholecystectomy for gallstones. OCTT was measured by means of the hydrogen breath test after administering a liquid meal of 10 g of lactulose in 200 mL of water, and collecting exhaled breath samples every 10 minutes for 200 minutes. Of all subjects in the group of patients with a history of cholecystectomy, 6/20 were non- hydrogen producers, and therefore were not included in the study. The OCTT was found to be significantly longer in healthy elderly controls, than in healthy young adult controls; the elderly subjects who had undergone cholecystectomy had a longer OCTT than the healthy elderly controls, while no difference was detected when compared to elderly patients with gallstones. In conclusion, OCTT seems to increase in healthy aging. Cholecystectomy also increases OCTT in the elderly, suggesting a link between intestinal motility and the biliary tract which may be of pathophysiological significance. (Aging Clin. Exp.

Abstract

To ascertain whether aging and/or cholelithiasis can influence oro- cecal transit time (OCTT), we studied a total of 70 subjects, i.e., 10 healthy young adult controls, 22 healthy elderly controls, 18 elderly cholelithiasis patients and 20 elderly subjects with a history of cholecystectomy for gallstones. OCTT was measured by means of the hydrogen breath test after administering a liquid meal of 10 g of lactulose in 200 mL of water, and collecting exhaled breath samples every 10 minutes for 200 minutes. Of all subjects in the group of patients with a history of cholecystectomy, 6/20 were non- hydrogen producers, and therefore were not included in the study. The OCTT was found to be significantly longer in healthy elderly controls, than in healthy young adult controls; the elderly subjects who had undergone cholecystectomy had a longer OCTT than the healthy elderly controls, while no difference was detected when compared to elderly patients with gallstones. In conclusion, OCTT seems to increase in healthy aging. Cholecystectomy also increases OCTT in the elderly, suggesting a link between intestinal motility and the biliary tract which may be of pathophysiological significance. (Aging Clin. Exp.
