We compared the risk of anastomotic leakage across commonly used circular stapler platforms using advanced confounding control methods.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This pre\u2010planned post hoc analysis pooled individual patient data from the published iCral\u20102 and iCral\u20103 studies and from the iCral\u20104 study, whose primary results are currently under peer review. Adults undergoing elective left colectomy or high anterior resection with standardized end\u2010to\u2010end circular stapled anastomosis were included. Five circular stapler platforms were compared. Confounding was addressed using generalized boosted model\u2013based propensity score weighting targeting the average treatment effect on the treated, with doubly robust outcome modelling. The primary endpoint was overall anastomotic leakage at 60\u2009days.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Among 3,653 patients, overall anastomotic leakage occurred in 2.7% of patients receiving the reference 3\u2010row platform. After weighting, Platforms 3 and 4 were associated with a significantly increased risk of overall anastomotic leakage (odds ratios &gt;2), whereas no statistically significant differences were observed for Platforms 2 or 5. Because the effective sample size after weighting was substantially reduced for Platform 3 owing to limited covariate overlap, the corresponding effect estimate should be interpreted with appropriate caution.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Selected circular stapler platforms were associated with an increased risk of overall anastomotic leakage.
