Accidental ingestion is common and can even necessitate surgery. An 89-year-old man with dementia presented with abdominal distension and pain. A CT scan revealed a high-intensity object in the terminal ileum with distension of the proximal small intestine. Colonoscopy showed ileus caused by a retained foreign body (FB), which was removed via laparotomy the following day. Chemical analysis identified the material of the FB as platinum silicone rubber. Based on its material and irregular shape, the FB was determined to be a dental impression. The patient had dentures made one year prior, and cognitive decline may have contributed to the incident. Platinum silicone, which is odorless and does not deform with body heat or digestive juices, maybe a common cause of accidental ingestion.
意外摄入很常见，甚至可能需要进行手术。一名89岁的痴呆症男性患者出现腹胀和腹痛。CT扫描显示回肠末端有一个高密度物体，近端小肠扩张。结肠镜检查显示由异物残留导致的肠梗阻，第二天通过剖腹手术将异物取出。化学分析确定异物的材料为铂硅胶。根据其材料和不规则形状，确定该异物为牙印模。患者一年前制作了假牙，认知能力下降可能是导致这一事件的原因。铂硅胶无味，不会因体温或消化液而变形，可能是意外摄入的常见原因。
