Senate Majority Whip Dick Durbin (D-Ill.) Thursday underwent successful surgery to have a small gastrointestinal stromal tumor removed from his stomach, his office announced.

The successful surgery to remove the non-cancerous tumor took place at the University of Chicago Medical Center. Durbin is expected to be released from the hospital in the next few days.

“Sen. Durbin went through today’s surgical procedure with flying colors and is resting comfortably,” said Durbin spokesman Joe Shoemaker.

“He expects to be released from the hospital and resume a light schedule in the next couple days, and should be able to resume a full schedule as soon as next week,” he added.
