“…The overall accuracy was high, 94% for offline reading and 96% for bedside reading. These results fit well into findings from other comparative studies of grayscale ultrasound imaging where the non-perfect agreement is attributed to the technical limitations of ultrasound imaging (14,15). We could not find any significant difference in the diagnostic performance between the immediate reading of the performing radiologist and the offline reading of a blinded radiologist, thereby showing that ultrasound scans can be evaluated reliably by a non-performing reader.…”

“…Acute abdominal pain can be either surgical or medical, in origin, so effective treatment is dependent upon correct diagnosis. The acute abdomen has a broad spectrum of causes ranging from benign selflimiting conditions to diseases with high morbidity and mortality [2,3]. Therefore, early diagnosis and treatment are important.…”

Our aim was to assess the effects of initial ultrasonography (US) evaluation on the diagnosis and management of non-traumatic acute abdominal pain in the emergency department. Three hundred patients with the complaint of non-traumatic acute abdominal pain who were sent for US examination with an initial clinical impression were included in the study. Pre-US and post-US surveys were designed for the clinicians who requested US. The percentage concordance of US findings with the discharge diagnosis made by clinical follow-up, imaging modalities and surgery was determined by calculating the confidence interval. The concordance of the initial clinical impression and the US diagnosis with the discharge diagnosis were compared using the McNemar test. US could not detect any pathology in 102 (34%; 95%CI, 28.6-39.3%) of the patients. The US revealed a different diagnosis than the clinical impression in 69 (23%; 95%CI, 18.2-27.7%), and confirmed the diagnosis in 121 (40%; 95%CI, 34.4-45.5%) patients. The US changed the treatment plans in 47% (95%CI, 41.3-52.6%) of the patients. The clinicians stated US helped them "very much" or "moderately" in making a diagnosis in 83% (95%CI, 78.7-87.2%). When US results were compared with the discharge diagnosis, there was concordance in 238 (79.3%; 95%CI, 74.3-83.6%) patients but not in 62 (20.6%; 95%CI, 16-25.1%). Among 121 patients the initial clinical impression agreed with the US diagnosis and there was concordance with the discharge diagnosis in 105 (86.7%; 95%CI, 80-92.7%). The concordance of US findings with the discharge diagnosis was significantly higher than that of the initial clinical impression statistically. In the initial evaluation of the patients with acute abdominal pain, US is considerably helpful in making the correct diagnosis, and that the concordance with the discharge diagnosis is high. When whole abdominal scanning is not performed, targeted US study according to the initial clinical impression decreases the clinical benefit of US.

“…Ultrasonography has been widely used by emergency physicians to accurately diagnose many disease processes at the bedside with high sensitivity and specificity. [15][16][17][18] Improvements in ultrasound technology, and increasing clinical experience with ultrasonography, has led to its common use in situations such as thoracoabdominal trauma, ectopic pregnancy, abdominal aortic aneurysm, pericardial effusion, cardiac arrest, biliary disease, renal tract disease, and small bowel obstruction, and in procedures such as lumbar puncture, arthrocentesis and central venous access. [18][19][20] As a result, the emergency physician is ideally suited for the use of ultrasound technology at the patient's bedside since these physicians are frequently presented with acutely ill or injured patients requiring immediate treatment.…”
