We conducted a multicenter retrospective study to evaluate the association between postoperative residual ileocolic artery length (RIAL), a surrogate marker of residual mesenteric burden, and endoscopic recurrence (ER) in CD.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This multicenter retrospective study involved patients with CD who underwent ileocolic resection between January 2019 and December 2024. RIAL was measured using postoperative contrast-enhanced computed tomography. The primary outcome was ER at the first endoscopic assessment. Least absolute shrinkage and selection operator (LASSO) logistic regression was used to identify predictors of ER and to construct a nomogram. Kaplan\u2013Meier and Cox regression analyses were applied to evaluate ER outcome within 36\u2009months after surgery.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Among 270 patients, 90 (33.3%) developed ER at the first postoperative endoscopy. LASSO logistic regression and the derived nomogram identified that a longer RIAL was associated with an increased risk of ER. ROC curve analysis identified 32.8\u2009mm as the optimal cutoff of RIAL for predicting ER. Kaplan\u2013Meier curve showed that patients with a RIAL\u2009&amp;lt;\u200932.8\u2009mm had significantly longer ER-free survival (log-rank P\u2009&amp;lt;\u2009.001). Cox analysis identified an RIAL\u2009&amp;lt;\u200932.8\u2009mm and the postoperative use of biologics were independent protective factors for ER-free survival.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Postoperative ER risk was positively correlated with RIAL in CD.
