A Hong Kong hospital has completed the city's first combined heart and liver transplant in a 20-hour operation involving almost 70 medical staff.

An unidentified 27-year-old woman received the organs from a brain-dead donor, while giving her own failing but still usable liver to a 62-year-old man with liver cancer, a Queen Mary Hospital spokeswoman said.

The operation, on Friday, was deemed a success and both patients were in a "satisfactory condition", she said.
