高频超声在儿童消化道异物诊断中的应用价值

摘要

目的 探讨高频超声在儿童消化道异物诊断中的应用价值.方法 回顾性分析我院9例经超声诊断并经胃镜或手术证实的消化道异物患儿(年龄9个月至11岁)的超声声像图特点,并与X线平片结果对照.结果 9例患儿超声均清晰显示异物具体位置及与周围脏器关系.2例异物嵌顿在幽门并造成幽门和(或)邻近器官损伤,小肠内磁铁异物造成闭襻梗阻1例,腹腔内鱼刺异物包裹1例,其余分别位于胃内3例,十二指肠1例,结肠1例,均未造成脏器损伤.所有异物的超声表现均为强回声,无声影.7例同时行平片检查,均仅显示异物位于上、中、下腹区域.结论 高频超声检查可以清晰显示异物的位置,与周围脏器的关系,弥补X平片的不足,有助于治疗方案的选择.%Objective To evaluate the value of high frequency ultrasound in diagnosis of foreign body in digestive tract. Methods The ultrasound features of 9 patients ( the ages ranging from 9 month to 11 years old ) with ingested foreign bodies were retrospectively analysed and were diagnosed by ultrasound. The results were confirmed by endoscopy or operation. The X-ray film findings were also compared.Results The location and relationship with surround organs of all the foreign bodies were clearly demonstrated by ultrasonography. The foreign body was stuck into pylorus and the adjacent organs were injured in 2 cases. The magnet in bowel led to obstruction in 1 case. A fishbone that was wrapped up was located in one abdomen lumen.Others were located in stomach ( 3 cases ), duodenum ( 1 case ) and colon( 1 case ),and the surrounding organs were not injured. All the foreign bodies in our group were hypoechogenic without shadow. In X-ray film, the un-radiolucent foreign body could be detected, but the relationship with surrounding organ could not be definitely identified. Conclusion The high frequency ultrasonography can definitely identified the location of foreign body and its relationship with surrounding organs, which could be helpful for treatment options.
