RETROSPECTIVE EVALUATION THE CONCORDANCE OF IMAGING MODALITIES IN PATIENTS ADMITTED TO THE EMERGENCY DEPARTMENT WITH ABDOMINAL PAIN

: In the present study, we aimed to evaluate concordance of imaging modalities of patients admitted to the emergency department (ED) with abdominal pain. Material and Methods : The study was conducted between the dates 01.06.2014-31.05.2015 after the local ethical committee approval. Patients admitted to the ED, with abdominal pain, whose multiple imaging were done (abdominal ultrasonography; USG and computed tomography; CT) were screened for 1 year retrospectively. Data analysis was performed using SPSS 15.0. Results : The study included a total of 413 patients of which 242 (58.6%) of women. The final diagnosis of the patients, 133 (32.2%) patients had nonspecific abdominal pain, the most commonly seen surgical diagnosis was acute appendicitis. When the sensitivities of USG and CT evaluated regarding the final diagnosis it was 38.9% and 86.1%, respectively for acute appendicitis, 0% and 30.4% respectively for acute pancreatitis, 65.4% and 98.1% respectively for ovarian pathology, 94.9% and 87.2% respectively for acute cholecystitis. There was detected concordance in 63.2% between USG and CT. While this rate was 61.7% among recent diagnosis with USG, for CT recent diagnoses it was found as 87.7%. Conclusion : In conclusion, when final diagnoses are compared with imaging methods in patients with abdominal pain, CT seems superior to USG. Especially in clinics where USG cannot be performed for 24 hours like in our clinic, CT may be preferred as the first imaging method.
