Pope Francis on Wednesday left the Rome hospital where the 84-year-old pontiff underwent an operation on his colon on July 4, an AFP photographer said.
The pontiff left the Gemelli University Hospital for the Vatican in a car with darkened windows, the photographer said.
Francis had been admitted after suffering from a type of diverticulitis, an inflammation of pockets that develop in the lining of the intestine.
The Vatican initially said he would be in hospital for about a week, and the pope led the Angelus prayer from his hospital window on Sunday.
On Monday, Vatican spokesman Matteo Bruni said he would stay for a “few more days”. Francis stayed in the same suite used by Pope John Paul II, who also leads the Angelus prayer from there. The Argentine pontiff temporarily ran a fever last week but a chest and abdomen scan and other tests revealed no particular abnormalities.
