Cystic intestinal duplication-induced secondary intussusception with associated incidental Meckel’s diverticulum in an infant: a case report with literature review

In pediatric patients with secondary intussusception caused by enteric duplication, meticulous intraoperative evaluation following successful reduction is critical to identify concurrent intestinal anomalies, including inverted Meckel's diverticulum-a potential lead point for secondary intussusception. This case highlights the incidental discovery of a coexisting Meckel's diverticulum, which was prophylactically excised despite lacking immediate pathological relevance. Systematic exploration combined with tailored resection strategies ensures definitive resolution of intussusception and long-term complication prevention in such rare dual-pathology presentations.
