Effects of resection or bypass of the distal ileum on the lithogenicity of bile.
Changes in the composition and lithogenicity of gallbladder bile after resection and bypass of the distal ileum were investigated in the prairie dog. In animals fed a trace cholesterol diet, both ileal resection and ileal bypass increased the cholesterol saturation of bile. In animals fed a cholesterol-enriched diet, the cholesterol saturation was increased by ileal resection but not by ileal bypass. In the animals fed the trace cholesterol diet, both ileal resection and ileal bypass induced the formation of bilirubinate gallstones.
