Pope Francis has “reacted well” to intestinal surgery Sunday at a Rome hospital, according to the Vatican. Holy See spokesman Matteo Bruni said the pope was under general anesthesia during the surgery, which was precipitated by narrowing of the large intestine. It’s unknown how long the surgery lasted. The news comes after the 84-year-old pontiff was hospitalized Sunday for symptomatic colon diverticulitis—a sometimes-painful condition in which bulging sacs form in the digestive tract. The pope has had a number of health issues in recent years, including sciatica.
