VALUE OF MULTI-DETECTOR COMPUTED TOMOGRAPHY IN THE DIAGNOSIS OF INTESTINAL OBSTRUCTION AT HAI PHONG INTERNATIONAL HOSPITAL, 2020-2022
Main Article Content
Abstract
Objectives: to describe the role of multi-detector computed tomography in diagnosing mechanical intestinal obstruction in patients treated at Haiphong International Hospital, 2020-2022. Subjects and methods: Cross-sectional descriptive study, all patients were diagnosed with mechanical intestinal obstruction, had multi-detector CT scan with contrast agent and had surgery at the Haiphong International Hospital from January 2020 to August 2022. Results and conclusion: Sensitivity (Se), specificity (Sp), positive predictive value (PPV), negative predictive value (NPV) in diagnosing the cause of intestinal obstruction due to tumor were 90%, 100%, respectively. 100% and 97.8%, due to ligaments were 78.3%, 93.7%, 90%, 85.7% and due to adhesions were 59.1%, 84.8%, 72.2% and 76.6%. For causes due to food residue, internal hernia, and torsion, the negative predictive value was high, ranging from 93.8% to 100%. Diagnosis of portal venous air and abdominal free air with high Se, Sp, PPV and NPV were all 100%. Thus, CT scan is a highly valuable technique in diagnosing intestinal obstruction, diagnosing the cause and the complications of this disease.
