Pope Francis undergoes abdominal surgery and hospitalization.

Pope Francis, 86, is undergoing abdominal surgery to treat a "recurrent, painful and worsening" constriction of the intestine at Rome's Gemelli hospital. The Vatican said Francis would be put under general anesthesia for the procedure and would be hospitalized for several days. Francis had part of one lung removed when he was a young man and also suffers from sciatica nerve pain. He had 33 centimeters of his colon removed two years ago.
