THE VALUATIONS OF COMPUTED TOMOGRAPHY IN NON TRAUMATIC ACUTE ABDOMINAL PAIN AT HUE UNIVERSITY OF MEDICINE AND PHARMACY HOSPITAL

Abstract

Background: Acute abdominal pain (AAB) accounts for 4-10% of hospitalizations at the emergency department. Diagnostic imagings, especially computed tomography (CT) plays an important role for etiological diagnosis and management, improve the accuracy from 71% to 93%. The increasing of indications and wide availability of the method increases ionizing radiation exposure. Purposes: Emphasing the importance of CT for AAB and evaluating the diagnosed value of portal single phase CT which aims at reducing radiation exposure. Materials and methods: A study on 90 patients with non traumatic AAB admitted to Hue University of Pharmacy and Medicine Hospital from July 2019 to March 2020. The CT results were correlated with surgical or final diagnosis. Results: Frequent diagnoses were acute appendicitis (20%), diverticulitis (17.8%), urinary stones (17.8%) and small or large bowel obstructions (14.4%). The sensitivity and specificity of multiphasic CT are 96.4% and 100%; the sensitivity and specificity of ultrasound and portal single phase CT combination are 97.6% and 100. The diagnostic match of the two protocols achieved a high value of 98.9%. DLP redution is 67%. Conclusions: CT has a high sensitivity and specificity in AAP etiological diagnosic. Combination of ultrasound and portal single phase CT is useful in diagnosis some AAP cases.
