Abstract
Introduction/Purpose Ultrasound is the first-line imaging modality for suspected acute cholecystitis. This can be radiology-performed ultrasound or point-of-care ultrasound (POCUS). POCUS can potentially streamline patient assessment in the emergency department (ED). The primary objective was to evaluate the literature for the diagnostic accuracy of POCUS performed for acute cholecystitis in the ED. Secondary objectives were to assess the effect of POCUS operator training on diagnostic accuracy for acute cholecystitis, utility of POCUS measurement of the common bile duct and POCUS impact on resource utilisation. Methods A systematic scoping review of articles was conducted using Medline, Embase, CENTRAL and CINAHL. Original studies of adults with POCUS performed for the diagnosis of acute cholecystitis in the ED were included. The study was reported using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews checklist (PRISMA-ScR). Results A total of 1090 publications were identified. Forty-six met the eligibility criteria. Studies were thematically grouped into categories according to specified objectives. Point-of-care ultrasound was of acceptable but variable accuracy, contributed to by the absence of a consistent reference standard and uniform training requirements. It may positively impact ED resource utilisation through reduced ED length of stay and radiology-performed imaging, whilst improving patient experience. Conclusion This review highlights the heterogeneity of existing research, emphasising the need for standardisation of training and reference standards in order to precisely define the utility of POCUS for acute cholecystitis in the ED and its benefits on ED resource utilisation.

Role of point-of-care ultrasound in critical care and emergency medicine: update and future perspective. Clin Exp Emerg Med 2023; 10:363-381. [PMID: 38225778 PMCID: PMC10790072 DOI: 10.15441/ceem.23.101] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/29/2023] [Revised: 10/01/2023] [Accepted: 10/05/2023] [Indexed: 01/17/2024] Open
Abstract
Point-of-care ultrasound (POCUS) is a rapidly developing technology that has the potential to revolutionize emergency and critical care medicine. The use of POCUS can improve patient care by providing real-time clinical information. However, appropriate usage and proper training are crucial to ensure patient safety and reliability. This article discusses the various applications of POCUS in emergency and critical care medicine, the importance of training and education, and the future of POCUS in medicine.

Abstract
Abdominal pain is a common presenting complaint in the emergency department, and utilization of diagnostic imaging is often a key tool in determining its etiology. Plain radiography has limited utility in this population. Computed tomography (CT) is the imaging modality of choice for undifferentiated abdominal pain. Ultrasound and magnetic resonance imaging may be helpful in specific scenarios, primarily in pediatrics and pregnancy, and offer the benefit of eliminating ionizing radiation risk of CT. Guidance for imaging selection is determined by location of pain, special patient considerations, and specific suspected etiologies. Expert guidance is offered by the American College of Radiology Appropriateness Criteria® which outlines imaging options based on location of pain.

The Utility of Hepatobiliary Scintigraphy Scans in the Tokyo Guidelines Era for Acute Cholecystitis. J Surg Res 2021; 268:667-672. [PMID: 34481220 DOI: 10.1016/j.jss.2021.08.009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/06/2021] [Revised: 07/27/2021] [Accepted: 08/04/2021] [Indexed: 12/07/2022]
Abstract
BACKGROUND Hepatobiliary Scintigraphy (HIDA) aids the diagnosis of acute cholecystitis (AC) but has limitations. We sought to design a model based on the Tokyo Guidelines 2018 (TG18) to predict HIDA results. METHODS A retrospective review of patients who underwent a HIDA scan during the evaluation of AC was performed. Using logistic regression techniques incorporating the TG18 criterion and additional readily available patient characteristics, a prediction model was created to identify patients likely to test negative for acute cholecystitis by HIDA scan. RESULTS In 235 patients with suspected AC, a HIDA scan was performed. Variables associated with positive HIDA results were male gender (RR 2.0 (CI 1.33-2.99), age (OR 1.02 (CI 1.01-1.04), right upper quadrant tenderness (RR 1.7 (CI 1.1-2.8)), clinical Murphy's sign (RR 2.2 (CI 1.5-3.4)), ultrasound findings suggestive of AC by any of its components (RR 3.2 (CI 1.6-6.5)), gallbladder wall thickening (RR 2.0 (CI 1.3-3.1)), and gallbladder distention (RR 1.9 (CI 1.3-2.9)). These variables allowed for creation of a model to predict HIDA results. The model predicted HIDA results in 36.9% of patients with an area under the curve of 0.81. CONCLUSIONS In the era of TG18, HIDA is probably over utilized. We developed an accurate, simple model based on TG18 that identifies a group of patients for whom a HIDA scan is unnecessary to establish the diagnosis of AC.

Abstract
BACKGROUND In 2008 the Council of Emergency Medicine Residency Directors delineated consensus recommendations for training in biliary ultrasound for the "detection of biliary pathology". OBJECTIVES While studies have looked at the accuracy of emergency provider performed clinical ultrasound (ECUS), we sought to evaluated if ECUS could be diagnostic for acute cholecystitis and thus obviate the need for follow-up imaging. METHOD We reviewed all ECUS performed between 2012 and 2017 that had a matching radiology performed ultrasound (RADUS) and a discharge diagnosis. 332 studies were identified. The sensitivity and specificity of both ECUS and RADUS were compared to the patient's discharge diagnosis. The agreement between the ECUS and RADUS was assessed using an unweighted Cohen's Kappa. The time from patient arrival to diagnosis by ECUS and RADUS was also compared. RESULTS Using discharge diagnosis as the gold standard ECUS was 67% (56-78%) sensitive, 88% (84-92%) specific, NPV 90% (87-95%), PPV 60% (50-71%), +LR 5.6 (3.9-8.2), -LR 0.37 (0.27-0.52) for acute cholecystitis. RADUS was 76% (66-87%) sensitive, 97% (95-99%) specific, NPV 95% (092-97%), PPV 86% (76-95%), +LR 25.6 (12.8-51.4), and -LR 0.24 (0.15-0.38). ECUS was able to detect gallstones with 93% (89-96%) sensitivity and 94% (90-98%) specificity leading to a NPV 90% (85-95%), PPV of 95% (92-98%), +LR 14.5 (7.7-27.4), -LR 0.08 (0.05-0.13). The unweighted kappa between ECUS and RADUS was 0.57. The median time between obtaining ECUS vs. RADUS diagnosis was 124 min. CONCLUSIONS ECUS can be beneficial in ruling out acute cholecystitis, but lacks the test characteristics to be diagnostic for acute cholecystitis.

Surgeon-performed point-of-care ultrasound for acute cholecystitis: indications and limitations: a European Society for Trauma and Emergency Surgery (ESTES) consensus statement. Eur J Trauma Emerg Surg 2019; 46:173-183. [PMID: 31435701 DOI: 10.1007/s00068-019-01197-z] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2019] [Accepted: 07/26/2019] [Indexed: 02/07/2023]
Abstract
BACKGROUND Acute cholecystitis (AC), frequently responsible for presentation to the emergency department, requires expedient diagnosis and definitive treatment by a general surgeon. Ultrasonography, usually performed by radiology technicians and reported by radiologists, is the first-line imaging study for the assessment of AC. Targeted point-of-care ultrasound (POCUS), particularly in the hands of the treating surgeon, may represent an evolution in surgical decision-making and may expedite care, reducing morbidity and cost. METHODS This consensus guideline was written under the auspices of the European Society of Trauma and Emergency Surgery (ESTES) by the POCUS working group. A systematic literature search identified relevant papers on the diagnosis and treatment of AC. Literature was critically-appraised according to the GRADE evidence-based guideline development method. Following a consensus conference at the European Congress of Trauma & Emergency Surgery (Valencia, Spain, May 2018), final recommendations were approved by the working group, using a modified e-Delphi process, and taking into account the level of evidence of the conclusion. RECOMMENDATIONS We strongly recommend the use of ultrasound as the first-line imaging investigation for the diagnosis of AC; specifically, we recommend that POCUS may be adopted as the primary imaging adjunct to surgeon-performed assessment of the patient with suspected AC. In line with the Tokyo guidelines, we strongly recommend Murphy's sign, in conjunction with the presence of gallstones and/or wall thickening as diagnostic of AC in the correct clinical context. We conditionally recommend US as a preoperative predictor of difficulty of cholecystectomy. There is insufficient evidence to recommend contrast-enhanced ultrasound or Doppler ultrasonography in the diagnosis of AC. We conditionally recommend the use of ultrasound to guide percutaneous cholecystostomy placement by appropriately-trained practitioners. CONCLUSIONS Surgeons have recently embraced POCUS to expedite diagnosis of AC and provide rapid decision-making and early treatment, streamlining the patient pathway and thereby reducing costs and morbidity.

Abstract
BACKGROUND Acute cholecystitis (AC) is a common differential for patients presenting to the emergency department (ED) with abdominal pain. The diagnostic accuracy of history, physical examination, and bedside laboratory tests for AC have not been quantitatively described. OBJECTIVES We performed a systematic review to determine the utility of history and physical examination (H&P), laboratory studies, and ultrasonography (US) in diagnosing AC in the ED. METHODS We searched medical literature from January 1965 to March 2016 in PubMed, Embase, and SCOPUS using a strategy derived from the following formulation of our clinical question: patients-ED patients suspected of AC; interventions-H&P, laboratory studies, and US findings commonly used to diagnose AC; comparator-surgical pathology or definitive diagnostic radiologic study confirming AC; and outcome-the operating characteristics of the investigations in diagnosing AC were calculated. Sensitivity, specificity, and likelihood ratios (LRs) were calculated using Meta-DiSc with a random-effects model (95% CI). Study quality and risks for bias were assessed using the Quality Assessment Tool for Diagnostic Accuracy Studies. RESULTS Separate PubMed, Embase, and SCOPUS searches retrieved studies for H&P (n = 734), laboratory findings (n = 74), and US (n = 492). Three H&P studies met inclusion/exclusion criteria with AC prevalence of 7%-64%. Fever had sensitivity ranging from 31% to 62% and specificity from 37% to 74%; positive LR [LR+] was 0.71-1.24, and negative LR [LR-] was 0.76-1.49. Jaundice sensitivity ranged from 11% to 14%, and specificity from 86% to 99%; LR+ was 0.80-13.81, and LR- was 0.87-1.03. Murphy's sign sensitivity was 62% (range = 53%-71%), and specificity was 96% (range = 95%-97%); LR+ was 15.64 (range = 11.48-21.31), and LR- was 0.40 (range = 0.32-0.50). Right upper quadrant pain had sensitivity ranging from 56% to 93% and specificity of 0% to 96%; LR+ ranged from 0.92 to 14.02, and LR- from 0.46 to 7.86. One laboratory study met criteria with a 26% prevalence of AC. Elevated bilirubin had a sensitivity of 40% (range = 12%-74%) and specificity of 93% (range = 77%-99%); LR+ was 5.80 (range = 1.25-26.99), and LR- was 0.64 (range = 0.39-1.08). Five US studies with a prevalence of AC of between 10% and 46%. US sensitivity was 86% (range = 78%-94%) and specificity was 71% (range = 66%-76%); LR+ was 3.23 (range = 1.74-6.00), and LR- was 0.18 (range = 0.10-0.33). CONCLUSION Variable disease prevalence, coupled with limited sample sizes, increases the risk of selection bias. Individually, none of these investigations reliably rule out AC. Development of a clinical decision rule to include evaluation of H&P, laboratory data, and US are more likely to achieve a correct diagnosis of AC.

Abstract
Point-of-care ultrasonography (POCUS) is a useful imaging technique for the emergency medicine (EM) physician. Because of its growing use in EM, this article will summarize the historical development, the scope of practice, and some evidence supporting the current applications of POCUS in the adult emergency department. Bedside ultrasonography in the emergency department shares clinical applications with critical care ultrasonography, including goal-directed echocardiography, echocardiography during cardiac arrest, thoracic ultrasonography, evaluation for deep vein thrombosis and pulmonary embolism, screening abdominal ultrasonography, ultrasonography in trauma, and guidance of procedures with ultrasonography. Some applications of POCUS unique to the emergency department include abdominal ultrasonography of the right upper quadrant and appendix, obstetric, testicular, soft tissue/musculoskeletal, and ocular ultrasonography. Ultrasonography has become an integral part of EM over the past two decades, and it is an important skill which positively influences patient outcomes.

Abstract
OBJECTIVE To investigate the feasibility and significance of the clinical application of ultrasound score in assessing the clinical severity of acute cholecystitis in the elderly. METHODS Pre-surgery ultrasonography was performed on 72 elderly patients with acute cholecystitis who were scheduled for cholecystectomy to determine the score based on ultrasonic imaging features to reflect clinical severity. Prior to operation, the cases were classified as mild, moderate, and severe according to clinical manifestation. The significance of ultrasonography for the prediction of the severity of acute cholecystitis and its pre-surgery guidance were evaluated based on intraoperative findings and postoperative pathology. RESULT In the aspect of clinical severity, of the 72 cases, 36 were mild, 21 were moderate, and 15 were severe. The cases that showed enlarged gallbladders, thickened gallbladder walls, double-layer images, gallbladder stones, incarcerated gall-stones, echoes in gallbladder fluid, peri-gallbladder effusions, or adherences were mostly moderate and severe cases. The difference in these cases with the mild cases exhibited statistical significance (P < 0.05). Of the 28 cases that scored ≤5, 26 (92.68 %) were mild cases. The 26 cases that scored between 6 and 9 mainly consisted of 15 moderate cases (57.7 %). The 18 cases that scored ≥10 mainly consisted of 13 severe cases (72.2 %). Significant differences were found in the cholecystostomy cases among the three groups (P < 0.05). CONCLUSION Prior to cholecystectomy, ultrasound score could accurately determine the severity of acute cholecystitis in the elderly and may be used as a reference for surgical intervention timing and mode selection to guide clinical therapy.

Abstract
Simulation training in sonography has been shown be an effective method of teaching and assessing user competency in image acquisition/interpretation and performance of procedures. Gallbladder simulation models that are currently commercially available are entire torso section phantoms, are generally expensive to obtain, and require maintenance. We have developed a sonographic gallbladder simulation model constructed using readily available and inexpensive materials. Models were created of normal gallbladder anatomy as well as various gallbladder pathologies such as cholelithiasis, biliary sludge, and thickening of the gallbladder wall. This model can be used to train users both to obtain and interpret sonographic images of the gallbladder.

Abstract
Hepatobiliary scintigraphy is a mature imaging technique for evaluation of patients with acute cholecystitis (AC). It is effective in calculous and acalculous forms of AC. The test is used in contemporary medical practice as the arbiter when the findings from screening abdominal ultrasound do not fit a clinical picture. It is also performed in severely ill patients who have AC suspected on other testing, but whose frail condition and high operative risk demand the highest level of certainty. This review, therefore, examines all technique variations of hepatobiliary scintigraphy, offering an approach that may best fit a variety of clinical situations and philosophies on AC.
