Justice Ginsburg in the Hospital Again

WASHINGTON — Justice Ruth Bader Ginsburg, who recently announced that she has been undergoing chemotherapy to address a recurrence of cancer, was back in the hospital on Wednesday, this time for what a Supreme Court spokeswoman called “a minimally invasive nonsurgical procedure.”

The procedure, to “revise a bile duct stent,” was performed at Memorial Sloan Kettering Cancer Center in New York. “According to her doctors, stent revisions are common occurrences and the procedure, performed using endoscopy and medical imaging guidance, was done to minimize the risk of future infection,” the spokeswoman, Kathleen Arberg, said in a statement.

“The justice is resting comfortably and expects to be released from the hospital by the end of the week,” Ms. Arberg said.

Justice Ginsburg, who is 87 and the senior member of the court’s liberal wing, has been hospitalized several times in recent months. In May, she participated in oral arguments from her hospital room at the Johns Hopkins Hospital in Baltimore, where she was being treated for a gallbladder condition.
