In pediatric patients, recurrent complications such as intussusception often result in frequent surgeries. This study aimed to identify clinical risk factors for small bowel polyp recurrence in children with PJS.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We retrospectively analyzed 64 pediatric PJS patients who had at least two follow\u2010up visits. Clinical data, including demographics, clinical features, and endoscopic findings, were collected. The primary outcome was recurrence of small bowel polyps, defined as polyps with a maximum diameter\u2009\u2265\u200915\u2009mm. Kaplan\u2013Meier survival curves and Cox proportional hazards models were used to assess risk factors.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The cohort's median age was 8.0 years, with a male\u2010to\u2010female ratio of 1.78:1. The median time to recurrence of small bowel polyps was 36.4 months. The estimated recurrence rates at 12, 24, and 36 months were 19.8% (95% confidence interval [CI]: 9.0%\u201329.3%), 33.2% (95%CI: 18.9%\u201344.9%), and 46.2% (95%CI: 28.0%\u201359.7%), respectively. Patients with a higher number of polyps (\u226510) and larger polyp size (\u22652\u2009cm in diameter) exhibited a more rapid recurrence. Multivariate Cox regression analysis identified that the number of small bowel polyps (\u226510) (hazard ratio [HR] 5.61, 95%CI: 1.65\u201319.09) and polyp size (HR 1.20, 95%CI: 1.01\u20131.42) were significantly associated with an increased risk of recurrence.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Greater polyp number (\u226510) and larger polyp diameter are independent risk factors for recurrence.
