Abstract：
We report the case of ileo-ileal intussusception secondary to a Peutz-Jeghers syndrome (PJS) hamartomatous polyp in a male infant. The patient presented with non-bilious vomiting and a single episode of passing blood in his stool. An upper gastrointestinal contrast study showed proximal bowel obstruction. At laparotomy, ileo-ileal intussusception was identified with a papillary mass acting as a lead point. The mass was resected, and a primary anastomosis was performed. The patient recovered well and was discharged on postoperative day 5. Histological assessment diagnosed a PJS hamartoma. The patient was well at 1 month follow-up. This case report describes a rare cause of intussusception in an infant that should be considered in the differential diagnosis. The diagnosis of PJS in infancy is uncommon and requires long-term follow-up.
摘要：
我们报告了男性婴儿中继发于Peutz-Jeghers综合征（PJS）错构瘤息肉的回肠回肠肠套叠的病例。患者表现为非胆汁性呕吐和一次粪便中的血液通过。上消化道造影研究显示近端肠梗阻。在剖腹手术中，回肠-回肠肠套叠以乳头状肿块为导点。肿块被切除了，并进行了一次吻合。患者恢复良好，术后第5天出院。组织学评估诊断为PJS错构瘤。患者在1个月随访时情况良好。此病例报告描述了婴儿肠套叠的罕见原因，应在鉴别诊断中予以考虑。婴儿期PJS的诊断并不常见，需要长期随访。
