Osaka University Hospital apologizes for mixing up two patient samples. Hospital accused of mistakenly giving the test results of cancer to a patient who did not have cancer and performing surgery.
The male patient was mistakenly given the test result that he had cancer, and surgery was performed to remove tissue from his stomach using a laparoscopy. A detailed examination of the tissue removed after the surgery revealed that it was not cancer but a lesion called ``ectopic pancreas.'' When the hospital investigated, it was discovered that the sample had been mixed up.
