The 78-year-old Barker is currently recovering at the George Washington University Hospital in Washington, D.C., after hourlong surgery to treat his enlarged prostate.
"The procedure went exactly as planned, without complications," said Dr. Michael Manyak, chairman of the hospital's department of urology.
"Mr. Barker is resting quite comfortably, and I expect him to be up and about very soon with a return to California in a few days," Manyak said.
The surgery won't affect Barker's hosting duties on The Price Is Right. He timed the procedure to take place during the show's summer hiatus, and he is expected to be fully healed by the time taping resumes, says his publicist, Henri Bollinger.
Barker is no stranger to the George Washington University Hospital. After suffering a minor stroke in September 1999, he underwent surgery at the hospital days later to clear a blocked artery in his neck to prevent a more serious episode.
He also had surgery in Los Angeles in May 2000 to repair a bum knee.
Despite his various recent ailments, Barker has become the iron man of the game show world. The Guinness Book of World Records named him television's "Most Durable Performer" for performing on 3,524 consecutive episodes of his first game show, Truth or Consequences. (Guinness also named him "Most Generous Host in Television History" for awarding $55 million in prizes during his career--CBS now says that total exceeds $200 million.)
Barker's streak on Truth or Consequences ended after 18 years. By then, however, he had launched The Price Is Right. The latter, now 30 years old, is the longest-running game show on television, and Barker is under contract through 2006.
In May, he picked up the Daytime Emmy for Best Game Show Host. It was his 15th career trophy.
