New York Gov. George Pataki, showing no improvement five days after surgeons removed his appendix, was transferred Tuesday to a New York City hospital and underwent another operation.
Doctors operated to alleviate a blockage in Pataki's digestive system, said his spokesman, David Catalfamo.
Pataki, 60, checked himself into Hudson Valley Medical Center last Thursday complaining of severe abdominal pain. His appendix, which had begun to rupture, was removed.
Pataki, a three-term Republican, is considering a run for president in 2008.
