Accuracy and reliability of preoperative CT in perforated diverticulitis: Post hoc secondary analysis from the SCANDIV trial

In this selected cohort of patients with suspected perforated diverticulitis, re-evaluation of CT scans proved unreliable for detecting malignancies and fecal contamination. This suggests that preoperative CT cannot replace follow-up colonoscopy or colonography following laparoscopic lavage.
