- Effectiveness of ultrasound screening in right upper quadrant pain: A comparative study in a basic emergency servicePublication . Miravent, Sérgio; Lobo, Manuel; Figueiredo, Teresa; Jiménez, Carmen; Almeida, RuiBackground and Aims: The use of ultrasound screening is primarily facilitated by point‐of‐care ultrasound (POCUS) and its integration into healthcare systems is a result of the versatility of this imaging technique. This study intends to compare the accuracy and pertinence of sonographic findings obtained by a sonographer in a Basic Emergency Service (BES) with that of radiologists at referral hospital (RH) in Portugal. Methods: Twenty patients with right upper quadrant (RUQ) pain and suspected cholecystitis or biliary pathology underwent sonography screening using POCUS in the BES. They were then forwarded to the RH where a radiologist performed a conventional ultrasound exam on the same patients. The results of both exams were compared to determine if the findings obtained in the BES were confirmed by the radiologist in the RH. Results: In our sample, 60% of cases were related to biliary pathology, 20% were liver‐related, 10% had hepatopancreatic biliary etiology, and 10% had unknown etiology. A strong association between the sonographic findings in the BES and the RH was found in the variables “Sonographic Murphy sign” (V = 0.859; p = 0.001), “Cholelithiasis/Gallbladder sludge” (V = 0.840; p = 0.001), and “Intrahepatic biliary tract dilatation” (V = 0.717; p = 0.006). Adequate measures of agreement between the findings of the radiographer and radiologist were obtained for the “Sonographic Murphy sign” (k = 0.664; p = 0.001) and the presence of “Cholelithiasis/Gallbladder sludge” (k = 0.712; p = 0.000). Conclusion: Major biliary abnormalities were detected in patients with RUQ pain in BES using sonography. The correlation between the sonographic findings obtained by the sonographers at BES and those obtained by radiologists at the RH in Portugal was strong, showing that POCUS screening could be extended to other similar settings; however, more studies are needed.
- Pre-hospital ultrasonography screening for biliary disease in remote settingsPublication . Miravent, Sérgio; Jimenez, Cármen; Lobo, Manuel; Figueiredo, Teresa; Almeida, RuiScreening ultrasound, including Point of Care Ultrasonography (POCUS), is widely utilized for rapid clinical guidance in diverse healthcare settings. In this case report, a 34-year-old male with recurrent biliary colic symptoms underwent a Basic Emergency Service ultrasound, revealing a 13 mm gallbladder calculus and signs of inflammation, and was promptly referred to the hospital for further evaluation and treatment. Medical specialist confirmation at the hospital underscored the significance of early detection through POCUS. Despite inconclusive laboratory results, the detailed ultrasound assessment provided a comprehensive understanding, emphasizing the tool's value in averting complications. Thus, screening ultrasound played a pivotal role in justifying the hospital referral, showcasing its vital role in healthcare, especially in resource-limited settings. The judicious use of POCUS can lead to superior outcomes, avoiding unnecessary referrals for non-emergent cases.
