He left with the tumor gone in his stomach, but he had a metal retractor. The doctors admitted to their mistake by pulling a 13-inch retractor into Church's stomach. It's not the first time at the University of Washington Medical Center, though it's not normal. 2. 73, Semo was taken to Raleigh Grand Hospital, Berkeley, Virginia, for surgery to determine the cause of his abdominal pain. But during the operation, he experienced a phenomenon called anesthesia awareness, in which patients under general anesthesia could still feel pain, pressure or discomfort during the operation, but they could not move or communicate with the doctor. Due to insufficient anesthesia during the operation, Semo could feel the piercing of the surgeon's scalpel, which they believe led to his suicide two weeks later. 3. 17-year-old Jessica Sandilla died after receiving the wrong organ transplant. Duke university hospital in Durham, North Carolina, the doctor mistakenly blood type does not match the heart and lung transplantation to sandilla, realize work after serious mistakes, they immediately to the rare second transplant attempt to remedy, but because sandilla brain damage, and the resulting complications, accelerated her death. A young life had died prematurely. 4. At Milford Regional Medical Center in Massachusetts, an 84-year-old woman had planned to remove her gallbladder, but the surgeon had removed her right kidney! According to local newspapers, the careless surgeon misinterpreted the report, which had helped him perform the operation between the bleeding and the swelling, but the man still removed her kidney.
