Introduction: Periampullary malignancies have poor outcomes. Thus, identifying patients who can benefit from surgery while avoiding risks and possible complications is crucial. This study was designed to determine the accuracy of MDCT in diagnosing resectable tumors. Methodology and results: This retrospective case-control study included 28 randomly selected patients. Patients were divided into group A (preoperative staging via MDCT) and group B (control; staging via laparoscopy and MDCT).MDCT had a 100% sensitivity and accuracy in identifying signs of irresectability. For borderline staging, MDCT had an accuracy of 62.5% and 71% for groups A and B, respectively. MDCT had an overall accuracy of 75%, which decreased to 68.1% for borderline lesions. Laparoscopy was able to identify occult findings missed by radiological imaging. Three cases in group A and one in group B underwent unnecessary laparotomy, resulting in a false-negative rate of 21% and 7%, respectively, with an overall rate of 14.2%. The mean predictive value of CT was 100% and 68.1% in irresectable and resectable cancers, respectively. Conclusion: Although MDCT is highly accurate for high-stage cancers, in potentially resectable tumors, it’s less accurate. We recommend adding other adjuncts to avoid unindicated laparotomies. | ||||
