title: Bilary lipids and bile acid pool size after vagotomy in man. Evidence against a predisposition to gallstones.
abstract: Eight male subjects who had previously undergone vagotomy and pyloroplasty were found to have significantly larger bile acid pools than did a group of matched control subjects. Associated with these expanded pools was a significantly lower molar per cent cholesterol of gallbladder bile in the vagotomy group. These findings are the opposite of those expected in a group predisposed to cholesterol cholelithiasis, suggesting that vagotomy, at least in males, does not predispose to cholesterol gallstones. If such stones form after vagotomy, they presumably do so by a mechanism not presently appreciated.
