This report presents a case where an open safety pin passed through the Esophagus and where Nature herself finally solved the problem by closing the pin, which was afterwards carried in the faecal stream and discharged from the body without any harm to the patient.
一枚开口安全别针穿过了食管,而自然本身最终通过封闭别针解决了问题,该别针随后随粪便排出体外,未对患者造成任何伤害。
