The court said Dr Wisut killed his wife, obstetrician Phassaporn, in 2001, dismembering her and flushing her body parts down a toilet of a dormitory of Chulalongkorn University.
The Court of Appeal in July 2005 upheld a Criminal Court conviction and sentence of the Chulalongkorn Hospital doctor.
The victim's father, Chote Wattanachet, brought the case to courts after public prosecutors originally dropped charges, citing lack of evidence as the victims's body was never found.
Chote pursued Wisut in a civil action. Public prosecutors eventually took it up again and secured a conviction.
Chote argued in court that the lack of a body in the case was outweighed by the discovery of human flesh in a sewer near a Chulalongkorn University dormitory where Wisut lived.
On February 23, 2001, Dr Wisut lodged a missing person's report with the Phya Thai police that his wife went missing. Police learned Wisut was the last person to see Phassaporn alive during a meal together at the Siam Discovery Oishi restaurant.
Police recovered parts said to be Phassaporn at the dormitory and the Central Sofitel hotel in Lat Phrao.
Wisut was known to have argued with Phassaporn over property and an affair that later prompted his wife to seek a divorce.
