A hospital patient collapsed with a ruptured appendix a month after he thought it had been removed, he has claimed.
Mark Wattson, from Lower Stratton, near Swindon, was under the impression his appendix was removed after his "first" appendectomy on July 7.
He claimed doctors told him the procedure went well, and he was discharged on July 8.
But on August 7, the 35-year-old was taken to hospital by paramedics after doubling over in agony while job hunting in Swindon town centre.
He was told by doctors at Great Western Hospital that his appendix had burst and he needed an emergency appendectomy.
He told the Swindon Advertiser: "I couldn't believe what I was hearing. I told these people I had my appendix out just four weeks earlier but there it was on the screen for all to see.
"I thought 'What the hell did they slice me open for in the first place?'."
Mr Wattson was re-admitted for surgery and was released after the successful "second" procedure on August 9.
