Methods A national multicenter cohort study was conducted using data from a prospective audit performed in 75 Dutch hospitals. Patients undergoing curative resection for LSOCC (2009–2016) with available CT data on cecal diameter and small-bowel distention were included. Primary outcomes were 90-day postoperative complications and mortality, analyzed by multivariable logistic regression and stratified by treatment strategy (ER vs BTS). Results Of 1,282 patients, 967 underwent ER and 315 BTS. Among ER patients, concurrent cecal dilatation (≥9 cm) and small-bowel distention were independently associated with higher 90-day complications (58.8% vs 42.7%; OR 1.91, 95% CI 1.25–2.93; p= 0.003) and 30-day mortality (7.0% vs 2.7%; p= 0.038). These associations were absent in BTS patients. In this high-risk CT subgroup, BTS yielded fewer complications (37.4% vs 58.8%), lower permanent stoma rates (23.0% vs 52.1%), and higher primary anastomosis rates (85.4% vs 30.6%). In young (<70 years) and healthy patients (ASA I-II) without a dilated coecum or small bowel on CT, no outcome differences were found between ER or BTS. Conclusion Concurrent cecal dilatation and small-bowel distention on CT identify high-risk patients after ER, whereas BTS mitigates these risks. Routine CT-assessment may aid individualized management.</p> 2026-10-05T09:04:08Z Dataset Dataset 10.6084/m9.figshare.34068780.v1 https://figshare.com/articles/dataset/Supplemental_Material_for_Are_a_dilated_cecum_and_small_bowel_distention_on_CT_imaging_associated_with_worse_postoperative_outcomes_in_left-sided_obstructive_colon_cancer_A_population-based_study/34068780 CC BY 4.0
