纳入标准:

1.诊断明确:临床及超声诊断肠套叠。
2.患儿年龄:0-14岁;
3.资料完整:1)临床资料完整:性别、年龄以及病情转归记录临床资料完整,对于持续型肠套叠患儿,有灌肠复位或手术复位的临床记录。2)超声资料完整:对于套筒的直径、长度、部位、套筒周围肠系膜淋巴结情况有超声记录,对于一过型肠套叠患儿,有1小时内超声复查佐证肠套叠消失的影像学资料。

Inclusion criteria

1.Clear Diagnosis??: Clinically and ultrasonographically diagnosed intussusception; 2.Age: 0-14 years; 3.??Complete Data??: ??Clinical Data??: Complete records including gender, age, and disease outcome. For persistent intussusception cases, there should be clinical documentation of enema reduction or surgical reduction. ??Ultrasound Data??: Complete ultrasound records, including the diameter, length, and location of the intussusceptum, as well as the condition of the surrounding mesenteric lymph nodes. For transient intussusception cases, there should be follow-up ultrasound imaging within 1 hour confirming the resolution of intussusception.

排除标准:

1.资料缺失;
2.合并其他严重疾病:患有严重的先天性肠道畸形、恶性肿瘤等可能影响肠套叠病情转归或超声表现的其他严重疾病。
3.未行灌肠复位或手术复位,且未进行短期超声复查;

Exclusion criteria:

1.Incomplete Data??: Missing clinical or ultrasound records; 2.Severe Comorbidities??: Presence of other severe diseases such as congenital intestinal malformations, malignant tumors, or other conditions that may affect the outcome or ultrasound presentation of intussusception; 3.Lack of Follow-up??: Cases where neither enema reduction nor surgical reduction was performed, and no short-term ultrasound follow-up was conducted.

Target condition (The target condition is a particular disease or disease stage that the index test will be intended to identify. Please specify the characteristics in detail; the population should has a complete spectrum and good representative):

Children with ultrasonographically diagnosed intussusception at Wuhan Children's Hospital from July 2021 to July2022.

容易混淆的疾病人群(即与目标疾病不易区分的一种或多种不同疾病,应避免采用正常人群对照的病例-对照设计):

肠扭转或美克尔憩室内翻患儿

例数:

Sample size:
