超声引导下生理盐水灌肠治疗小儿急性肠套叠复位后短期复发的临床特征及超声影像表现

Short-term recurrence after reduction of pediatric acute intussusception in children treated with ultrasound-guided normal saline enema: clinical features and ultrasonic manifestations

目的分析超声引导下生理盐水灌肠治疗小儿急性肠套叠复位后短期复发的临床特征及超声影像表现。方法回顾性分析2015年6月至2021年2月深圳市宝安区妇幼保健院收治的762例生理盐水灌肠治疗小儿急性肠套叠复发患者的临床及超声资料。将患儿分为短期复发组78例和非短期复发组684例,比较两组患儿一般资料、临床特点、超声影像学特征和随访的病理结果。结果短期复发组患儿"套筒征"的平均长度为(5.69±0.83) cm,明显长于非短期复发组(4.33±0.64) cm;平均体质量为(13.53±3.14) kg,明显重于非短期复发组(10.85±2.96) kg,差异均具有统计学意义(P<0.05);此外,随访病理结果提示,两组患儿继发性因素比较差异也具有统计学意义(P<0.01),而性别、年龄、"靶环征"的平均直径、"套叠鞘部"的平均厚度、其他临床症状及特征比较差异均无统计学意义(P>0.05)。结论超声引导下生理盐水灌肠能够为治疗小儿急性肠套叠复位后短期复发的原因提供一定价值的临床特征及影像学信息。

Objective To analyze clinical characteristics and ultrasonic manifestations of short-term recurrence after reduction of acute intussusception in children treated by ultrasound-guided saline enema. Methods Clinical and ultrasound data of 762 patients with recurrence of acute intussusception in children treated by ultrasound-guided saline enema and received by Shenzhen Bao’an Maternal & Child Care Health Hospital from June 2015 to February 2021 were retrospectively analyzed. The children were divided into the short-term recurrence group(78 cases) and the non-short-term recurrence group(684 cases). The general data, clinical features, ultrasonic manifestations, and follow-up pathological results of the two groups were analyzed. Results The average length of the "sleeve sign" of children in the short-term recurrence group was(5.69±0.83) cm, which was significantly bigger than(4.33±0.64) cm of the non-short-term recurrence group;the average body mass was(13.53±3.14) kg, which was significantly bigger than(10.85±2.96) kg of the non-short-term recurrence group;the differences were statistically significant(P<0.05). In addition, follow-up pathological results showed that there was also a statistically significant difference between the two groups(P<0.01). The differences of gender, age, the average diameter of "target-ring sign", the average thickness of "intussusception", and other clinical symptoms and characteristics had no statistically significant difference(P>0.05). Conclusion The ultrasound-guided saline enema could provide valuable clinical characteristics and imaging information for the cause of the short-term recurrence after reduction of acute intussusception in children.
