A 17-year-old man from Italy had an appendectomy in 2019 at the Giannuzzi Hospital in Manduria. At the time, the procedure was considered routine, and no long-term complications were expected. However, the young man began experiencing severe abdominal pain shortly after the surgery, which persisted for two years. During this time, he visited the emergency room multiple times at various hospitals throughout the country. Each time, he was given pain relief medication but no clear diagnosis or treatment plan. In August 2021, a CT scan with contrast injection conducted at the Giannuzzi Hospital revealed a cylindrical metallic object inside his abdomen. It was identified as a surgical clip that had been accidentally left behind during the original appendectomy. To remove the clip, another surgical procedure was required. A medical and legal report prepared for the case criticized the hospital staff for "recklessness and negligence" and noted a violation of ethical standards. The report explained that the retained surgical clip led to internal adhesions, which caused biological damage and resulted in both emotional and financial harm to the patient. The pain caused by the retained clip forced the young man to leave his job as a dog handler with the Civil Protection Service. His lawyer is now seeking 50,000 euros in compensation for the damages he has incurred. The case has raised concerns about the importance of thorough post-operative checks and the potential consequences of medical errors. It also highlights the legal and ethical responsibilities of healthcare professionals to ensure patient safety and proper care.
