A 17-year-old man in Italy suffered from severe abdominal pain for several years after a surgical staple was accidentally left inside his body during an appendectomy in 2019. According to a report by Cittadella, an Italian radio station, the young man initially underwent a routine operation for appendicitis at an Italian hospital without any serious complications. However, in the years that followed, he experienced increasing abdominal pain that led to six visits to the emergency room across different hospitals. Each time, he was given painkillers but no definitive diagnosis or treatment. It was only after two years of suffering that a doctor at the same hospital where he had originally been operated on recommended a scan with contrast injection. The scan revealed a cylindrical metallic mass in his abdomen—a surgical staple or clip that had been left behind during the appendectomy. This kind of medical error, known as a retained foreign body, is a rare but serious complication of surgery. A new operation was subsequently scheduled to remove the staple, and a medical and legal report was prepared, which highlighted the presence of the forgotten staple and pointed out "the negligence and carelessness of the medical staff, as well as a violation of ontological rules." The term "ontological rules" refers to fundamental principles or standards that must be followed in a particular field—in this case, medical procedures. The report underscored the need for greater attention to detail and adherence to safety protocols in surgical practices. The incident has raised concerns about patient safety and the importance of thorough post-operative checks. While such cases are uncommon, they serve as a reminder of the potential risks associated with even routine surgical procedures. The young man's experience highlights the importance of proper medical follow-up and the need for hospitals to implement stricter protocols to prevent similar incidents.
