Objective To explore the sonographic features of ultrasound-guided incomplete hydrostatic reduction of pediatric intussusception.Methods We reviewed 15 cases of recurrence pediatric intussrscaption after saline enema reduction within 24 hours.The sonographic features,duration of the procedure,mesenteric lymphnodes and saline pressure were analyzed.Results There were no significant differences in the intussuscption site,saline pressure,operation duration and lymphnodes among recurred children within 24 hours.The recurrence cases showed no ileocecal valve closing after opening and incomplete entry of fluid into small intestine.Conclusions The recurrence pediatric intussusception within 24 hours was mainly caused by incomplete hydrostatic reduction.The characteristic sonographic features of incomplete reduction showed no ileocecal valve closing after opening and incomplete entry of fluid into small intestine.ldentifecation of these sonographic findings could avoid further surgical treatment.%目的 探讨超声引导下小儿肠套叠水压灌肠复位不全的超声声像图表现.方法 复习15例小儿肠套叠水压罐肠复位"成功"(最后诊断为复位不全)后24 h内又复套患儿,对其灌肠时超声图像表现、灌肠时间长短、最大水压力、进水量、肠系膜淋巴结肿大情况以及患儿发病时间长短的异同进行回顾性分析,对比短期内无复套的患儿,寻找短时间内(24 h内,下同)复套患儿的不同超声声像图表现.结果 短时间内复套患儿在套叠部位、水压力大小、操作时间长短以及淋巴结肿大方面均无明显差别,而其回盲瓣开放后无闭合动作,以及小肠进水时不彻底即复位不全是其共同点.结论 小儿肠套叠短时间内复套主要是水压灌肠复位不全引起的,回盲瓣开放后无闭合动作,小肠进水时部分小肠没有疏通是水压灌肠复位不全的特征性声像图表现.识别其复位不全的特征性超声表现可以避免短时间内再次水压灌肠或手术治疗.
