目的 比较电脑遥控灌肠整复仪与简易空气灌肠器对小儿肠套叠的整复效果，探讨更有效安全的空气灌肠设备。 方法 2002年11月－2011年11月对确诊的425例小儿肠套叠应用空气灌肠整复，其中198例采用简易空气灌肠器整复，227例用电脑遥控灌肠整复仪进行空气灌肠整复，并对不同病程时间、套叠部位与两种空气灌肠设备整复结果进行回顾性分析。 结果 198例患儿采用简易空气灌肠器整复成功率为71.2%，227例患儿采用电脑遥控灌肠整复仪的方式整复成功率为83.3%，后者成功率明显高于前者（P＜0.005），尤其是病程时间在24 h内，套叠部位位于升结肠或横结肠的后者整复成功率更高（P＜0.05）。 结论 电脑遥控灌肠整复仪比简易空气灌肠器更有效、安全。脉冲式空气灌肠能减轻套叠部位的痉挛与水肿，提高肠套叠的整复成功率。
ObjectiveTo study the clinical features,pathogenesis and differential diagnosis,and explore the imaging characteristics of congenital cystic adenomatoid malformation of the lung (CCAM) in children,in order to improve the knowledge of imaging findings of the disease. MethodsWe retrospectively analyzed the clinical data and imaging characteristics of three patients proven to have CCAM of the lung both by surgery and pathology between March 2011 and March 2013.Related literature was also reviewed,and two out of the three patients were followed up for two years. ResultsAll CCAM lesions in this study involved unilateral lower lobe,including two left lung and one right.Two patients had multiple large cysts containing gas,and one had multiple honeycomb-shaped vesicles.Histopathological examination showed that two cases were classified as Stocker type I and one as type Ⅱ,without type Ⅲ cases.Surgeries proved that the malformation was unilateral in all patients without connection with the bronchia.All patients with CCAM got complete cure by operation.The two-year postoperative follow-up showed an excellent recovery in all the patients. ConclusionImaging examination is the main basis for discovery and diagnosis of CCAM.The CT manifestations of CCAM are featured,and according to CT examination,pathological subtypes of the disease can be predicted.Being familiar with these characteristics is helpful for its diagnosis.
