Summarizing the clinical features of children with intussusception secondary to small bowel tumours and enhancing awareness of the disease. Retrospective summary of children with intussusception admitted to our emergency department from January 2016 to January 2022, who underwent surgery and were diagnosed with small bowel tumours. Summarize the types of tumours, clinical presentation, treatment, and prognosis. Thirty-one patients were included in our study, 24 males and 7 females, with an age of onset ranging from 1 m to 11y 5 m. Post-operative pathology revealed 4 types of small intestinal tumour, 17 lymphomas, 10 adenomas, 4 inflammatory myofibroblastomas and 1 lipoma. The majority of tumours in the small bowel occur in the ileum (83.9%, 26/31). Abdominal pain, vomiting and bloody stools were the most common clinical signs. Operative findings indicated that the small bowel (54.8%, 17/31) and ileocolic gut were the main sites of intussusception. Two types of procedure were applied: segmental bowel resection (28 cases) and wedge resection of mass in bowel wall (3 cases). All patients recovered well postoperatively, with no surgical complications observed. However, the primary diseases leading to intussusception showed slight differences in long-term prognosis due to variations in tumor types. Lymphoma is the most common cause of intussusception in pediatric patients with small bowel tumours, followed by adenoma. Small bowel tumours in children tend to occur in the ileum. Therefore, the treatment of SBT patients not only requires surgeons to address symptoms through surgery and obtain tissue samples but also relies heavily on the expertise of pathologists for accurate diagnosis. This has a significant impact on the overall prognosis of these patients.

小肠肿瘤继发小儿肠套叠31例临床特点回顾性研究

总结小肠肿瘤继发小儿肠套叠的临床特点，提高对该病的认识。 2016年1月至2022年1月我院急诊科收治的肠套叠患儿接受手术并诊断为小肠肿瘤的回顾性总结。总结肿瘤的类型、临床表现、治疗和预后。我们的研究共纳入 31 例患者，其中男性 24 例，女性 7 例，发病年龄为 1 m 至 11 岁 5 m。术后病理显示小肠肿瘤4例、淋巴瘤17例、腺瘤10例、炎性肌纤维母细胞瘤4例、脂肪瘤1例。小肠肿瘤大部分发生在回肠（83.9%，26/31）。腹痛、呕吐和血便是最常见的临床症状。手术结果显示，小肠（54.8%，17/31）和回结肠是肠套叠的主要部位。采用两种手术方式：节段性肠切除术（28例）和肠壁肿块楔形切除术（3例）。所有患者术后均恢复良好，未出现手术并发症。然而，由于肿瘤类型的差异，导致肠套叠的原发疾病在长期预后方面略有差异。淋巴瘤是小肠肿瘤儿科患者肠套叠的最常见原因，其次是腺瘤。儿童小肠肿瘤往往发生在回肠。因此，SBT患者的治疗不仅需要外科医生通过手术解决症状并获取组织样本，而且很大程度上依赖于病理学家的专业知识来进行准确的诊断。这对这些患者的总体预后有重大影响。
