A laboratory mistake at a Florida hospital resulted in unnecessary surgery for an elderly woman. The incident began when the 68-year-old Winter Park patient underwent a routine colonoscopy at the Orlando medical facility. When the tissue samples from the screening were evaluated, the results showed that she had developed cancer. However, pre-operative biopsy results that were administered later continued coming back negative as physicians attempted to determine the exact location of the cancer.
Though hesitant, the woman agreed to undergo a surgical treatment. Months after the surgery, the doctor called her with news that an examination of the tissues that the surgeon removed showed no evidence of cancer. Further DNA tests indicated that the initial diagnosis was incorrect, and reports say that that the woman's laboratory results were mixed up with those of a different patient. Sources say that the hospital did not provide a detailed account of records, documentation of the error or the steps employees performed to determine the outcome, and a lawsuit is now pending against the hospital for the violation of various state and federal laws.
