Edward's coronation had originally been scheduled for 26 June 1902. However, two days before he was diagnosed with appendicitis. The disease was generally not treated operatively. It carried a high mortality rate, but developments in anaesthesia and antisepsis in the preceding 50 years made life-saving surgery possible. Sir Frederick Treves, with the support of Lord Lister, performed a then-radical operation of draining a pint of pus from the infected abscess through a small incision (through -inch thickness of belly fat and abdomen wall); this outcome showed that the cause was not cancer. The next day, Edward was sitting up in bed, smoking a cigar. Two weeks later, it was announced that he was out of danger. Treves was honoured with a baronetcy (which the King had arranged before the operation) and appendix surgery entered the medical mainstream. Edward was crowned at Westminster Abbey on 9 August 1902 by the 80-year-old Archbishop of Canterbury, Frederick Temple, who died only four months later.
