title: Chronic bile duct cannulation of rhesus macaques (Macaca mulatta) without causing biliary fistulas.
abstract: Two surgical procedures were used for establishing chronic bile duct cannulations in rhesus macaques (Macaca mulatta) while maintaining an intact enterohepatic circulation for use in metabolism studies. One procedure resulted in the formation of biliary fistulas in all of the animals, whereas the other procedure allowed successful maintenance of the macaques without fistulation for up to 8 months after surgery. The possible importance of pressure against bile outflow in the development of the fistulas was discussed.
