The son of a man who died following complications after surgery for cancer has spoken of his fight to get to the truth of what happened.
Malcolm Green, 82, died after staff at Withybush hospital in Haverfordwest failed to tackle internal bleeding after the operation quickly enough.
His son John had to go through hospital records to prove a second operation took place later than first said.
Mr Green told BBC Wales it was appalling that the family had had "to prove a mistake had been made".
An inquest found that Mr Green received "less than optimum" care.
But Michael Howells, the assistant coroner for Pembrokeshire, said it did not amount to neglect.
Hywel Dda health board has admitted failings in the care of Malcolm Green.
