A three day inquest opens today into the death of an 82 year-old man who died at Withybush Hospital two years ago.
Malcolm Green's family say he became increasingly unwell after undergoing surgery for bowel cancer in June 2012.
They say staff failed to notice the deterioration in his condition and that he died of internal bleeding and organ failure because the surgeon who was supposed to be treating him left to go to a meeting.
The hospital have admitted "avoidable and unacceptable delays" in his treatment.
An inquest has been opened on a teenage girl killed in a fire while housesitting for her grandparents at their home in Aberdare. Eighteen-year-old Emily Harris was trapped inside the five-bedroomed home when the blaze broke out overnight at Plas Draw.
Her grandparents Keith and Ann Harris were away on holiday at the time but flew home after being told of the tragedy last weekend. Police and fire experts are investigating the blaze which gutted the £450,000 house.
Glamorgan and Valleys coroner Louise Hunt adjourned the Aberdare inquest pending a police investigation of the cause of the blaze.
A lorry driver has apologised to an inquest for waving a pedestrian across a road - just seconds before he was killed by a bus. Cement-mixer, Nicholas Morgan, said he waved the "OK" for walker Richard Taylor, 26, to cross a busy road.
But the inquest heard bridegroom-to-be Richard was hit by a bus because Mr Morgan failed to spot the bus. Richard died in hospital after being run over on his way to work in his office at an insurance company in Swansea.
He looked at me to see if it was okay to cross I looked in the other mirrors, there was a van and two cars in lane two. They went past and Richard looked at me again and I checked the outside lane. I suggested: 'Yes off to go'. He said "Thank you, no problem." But I didn't check my inside lane. There was nothing the coach driver could have done.

Swansea coroner, Philip Rogers, gave a verdict of accidental death saying, "It was a very tragic accident which has taken the life of a young man of considerable promise.
"It shows how a moment's lack of attention can lead to a tragic result."
