目的 探讨小儿胃肠异物适宜的治疗方法。方法 追踪随访门急诊收治的胃肠异物患儿。入组条件为:(1)不透X光异物;(2)非食管异物。结果 2009-01至2011-12，入组523例。平均(3.03±2.07)岁。男∶女为332∶191。首次就诊时胃内355例(67.9%)，肠道168例(32.1%)。胃内异物胃镜取出4例，余自行排出。肠道异物自行排出167例，一例未排出。异物中硬币最为多见(328例，62.7%)，均在4周内自行排出。不规则钝性异物37例，均自行排出。长形异物(长度≥2.5 cm)排出29例，胃镜取出3例，此3例异物长度均大于5 cm。锐性异物28例，包括图钉、开放状态安全别针、铁钉等，均自行排出。电池16例，纽扣电池12例，均自行排出;7号电池4例，胃镜取出1例，余自行排出。入组患儿无手术，无并发症及死亡。结论 绝大多数异物可自行排出，无需特殊处理。

Objective Try to find the appropriate way to managing gastrointestinal foreign bodies in children. Methods Following-up was performed in admitted patients with ingested FB in our hospital. The patients with nonopaque FB or FB located on esophagus were excluded the study. Results From Jan. 2010 to Dec. 2011, total 523 patients were enrolled into the study. The mean age was (3.03?2.07)years with a M/F ratio of 332/191. There were 355(67.9%)cases on admission with the stomach FB, and 168(32.1%)cases with the intestinal FB. Gastric FB proceeded uneventfully in 351 patients or was extracted by flexible endoscope in 4 patients. All except one intestinal FB was passed spontaneously down through the alimentary tract. The most common foreign bodies ingested are coins (328,62.7%). All of them were eliminated through normal bowel movement within 4 weeks. For large FB (longer than 2.5cm), natural elimination occurred in 29 cases and three cases were extracted by flexible endoscope. These 3 cases of FB were longer than 5cm. All sharp FBs (n=28) in our study passed out uneventful. Sixteen patients were found with battery ingestion, among them 12 were button batteries and 4 were cylindrical batteries. One cylindrical battery was removed by endoscope; the others passed through the gastrointestinal tract without complications. The outcome of all patients was uneventful. Conclusions The majority of ingested foreign bodies are able to be defecated spontaneously through the bowel movement; conservative treatment should be considered in priority for ingested FB in children.
