Stanley Ho, touted as one of Asia's richest man, has been hospitalized and had surgery in Hong Kong, his office said Tuesday. The brief statement did not say what surgical procedure the 87-year-old billionaire underwent. “He is in satisfactory condition and is progressing well in recovery,” the statement said. Ming Pao Daily cited Angela Leong, one of the four women Ho calls his “wives,” as saying last week that he needed treatment because of a rectal injury that he suffered two years ago following a procedure to relieve constipation. Ho, worth more than $9 billion according to Forbes, presided over Macau's casinos for four decades until his monopoly was broken up in 2002.
