Computed tomography versus ultrasound for the diagnosis of acute cholecystitis: a systematic review and meta-analysis. Eur Radiol 2024:10.1007/s00330-024-10783-8. [PMID: 38758253 DOI: 10.1007/s00330-024-10783-8] [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: 01/18/2024] [Revised: 04/03/2024] [Accepted: 04/13/2024] [Indexed: 05/18/2024]
Abstract
OBJECTIVES Some patients undergo both computed tomography (CT) and ultrasound (US) sequentially as part of the same evaluation for acute cholecystitis (AC). Our goal was to perform a systematic review and meta-analysis comparing the diagnostic performance of US and CT in the diagnosis of AC. MATERIALS AND METHODS Databases were searched for relevant published studies through November 2023. The primary objective was to compare the head-to-head performance of US and CT using surgical intervention or clinical follow-up as the reference standard. For the secondary analysis, all individual US and CT studies were analyzed. The pooled sensitivities, specificities, and areas under the curve (AUCs) were determined along with 95% confidence intervals (CIs). The prevalence of imaging findings was also evaluated. RESULTS Sixty-four studies met the inclusion criteria. In the primary analysis of head-to-head studies (n = 5), CT had a pooled sensitivity of 83.9% (95% CI, 78.4-88.2%) versus 79.0% (95% CI, 68.8-86.6%) of US (p = 0.44). The pooled specificity of CT was 94% (95% CI, 82.0-98.0%) versus 93.6% (95% CI, 79.4-98.2%) of US (p = 0.85). The concordance of positive or negative test between both modalities was 82.3% (95% CI, 72.1-89.4%). US and CT led to a positive change in management in only 4 to 8% of cases, respectively, when ordered sequentially after the other test. CONCLUSION The diagnostic performance of CT is comparable to US for the diagnosis of acute cholecystitis, with a high rate of concordance between the two modalities. CLINICAL RELEVANCE STATEMENT A subsequent US after a positive or negative CT for suspected acute cholecystitis may be unnecessary in most cases. KEY POINTS When there is clinical suspicion of acute cholecystitis, patients will often undergo both CT and US. CT has similar sensitivity and specificity compared to US for the diagnosis of acute cholecystitis. The concordance rate between CT and US for the diagnosis of acute cholecystitis is 82.3%.

[PMID: 38714552 DOI: 10.1007/s00059-024-05249-y] [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: 10/07/2023] [Revised: 01/31/2024] [Accepted: 04/03/2024] [Indexed: 05/10/2024]
Abstract
Roemheld syndrome (RS) is a condition that triggers cardiac symptoms due to gastrointestinal compression of the heart. It is often misdiagnosed as other types of cardiac or digestive disorders, leading to unnecessary treatments and reduced quality of life. Here, we provide a thorough review of RS, covering its pathogenesis, etiology, diagnosis, treatment, and outcome. We found that a number of conditions, including gallstones, hiatal hernia, excessive gas, and gastroesophageal reflux syndrome, can cause RS. The symptoms of RS can include chest pain, palpitations, shortness of breath, nausea, vomiting, bloating, and abdominal pain. Clinical history, physical examination, electrocardiograms, and improvement in symptoms following gastrointestinal therapy can all be used to identify RS. We also propose a set of criteria, the IKMAIR criteria, to improve the diagnostic approach for this condition. Dietary changes, lifestyle adjustments, pharmaceutical therapies, and surgical procedures can all be used to control RS. Depending on the underlying etiology and the outcome of treatment, RS has a varying prognosis. We conclude that RS is a complicated and understudied disorder that needs more attention from researchers and patients as well as from medical professionals. We recommend the inclusion of RS in the differential diagnosis for individuals with gastrointestinal problems and unexplained cardiac symptoms. Additionally, we advise treating RS holistically by attending to its cardiac and gastrointestinal components.

Abstract
BACKGROUND An updated overview of ultrasound (US) for diagnosis of acute cholecystitis (AC) remains lacking. This systematic review was conducted to evaluate the diagnostic performance of US for AC. METHODS A systematic review was conducted following PRISMA guidelines. We meticulously screened articles from MEDLINE, Embase, and the Cochrane Library, spanning from inception to August 2023. We employed the search strategy combining the keywords "bedside US", "emergency US" or "point-of-care US" with "AC". Two reviewers independently screened the titles and abstracts of the retrieved articles to identify suitable studies. The inclusion criteria encompassed articles investigating the diagnostic performance of US for AC. Data regarding diagnostic performance, sonographers, and sonographic findings including the presence of gallstone, gallbladder (GB) wall thickness, peri-GB fluid, or sonographic Murphy sign were extracted, and a meta-analysis was executed. Case reports, editorials, and review articles were excluded, as well as studies focused on acalculous cholecystitis. The study quality was assessed with the Quality Assessment of Diagnostic Accuracy Studies-2 (QUADAS-2) tool. RESULTS Forty studies with 8,652 patients were included. The majority of studies had a low risk of bias and applicability concerns. US had a pooled sensitivity of 71% (95% CI, 69-72%), a specificity of 85% (95% CI, 84-86%), and an accuracy of 0.83 (95% CI, 0.82-0.83) for the diagnosis of AC. The pooled sensitivity and specificity were 71% (95% CI, 67-74%) and 92% (95% CI, 90-93%) performed by emergency physicians (EPs), 79% (95% CI, 71-85%) and 76% (95% CI, 69-81%) performed by surgeons, and 68% (95% CI 66-71%) and 87% (95% CI, 86-88%) performed by radiologists, respectively. There were no statistically significant differences among the three groups. CONCLUSION US is a good imaging modality for the diagnosis of AC. EP-performed US has a similar diagnostic performance to radiologist-performed US. Further investigations would be needed to investigate the impact of US on expediting the management process and improving patient-centered outcomes.

Abstract
The files of patients with acute cholecystitis from two large university hospitals from the years 1978–1985 were employed to find the cases with acute gallbladder perforation for this study. Only those patients (n=9) were selected for the analysis of sonographic signs of acute gallbladder perforation who had less than 48 hours of symptoms before sonography, and were operated upon within 24 hours of the sonography. Patients (n=10) with non-complicated acute cholecystitis and identical in regard to the duration of the symptoms and the timing of the sonography and the operation formed a control group. The sonographic findings in patients with gallbladder perforation were pericholecystic fluid collections, free peritoneal fluid, disappearance of the gallbladder wall echoes, focal highly echogenic areas with acoustic shadows in the gallbladder, and an inhomogeneous, generally echo-poor gallbladder wall.

Abstract
PURPOSE To update previously summarized estimates of diagnostic accuracy for acute cholecystitis and to obtain summary estimates for more recently introduced modalities. MATERIALS AND METHODS A systematic search was performed in MEDLINE, EMBASE, Cochrane Library, and CINAHL databases up to March 2011 to identify studies about evaluation of imaging modalities in patients who were suspected of having acute cholecystitis. Inclusion criteria were explicit criteria for a positive test result, surgery and/or follow-up as the reference standard, and sufficient data to construct a 2 × 2 table. Studies about evaluation of predominantly acalculous cholecystitis in intensive care unit patients were excluded. Bivariate random-effects modeling was used to obtain summary estimates of sensitivity and specificity. RESULTS Fifty-seven studies were included, with evaluation of 5859 patients. Sensitivity of cholescintigraphy (96%; 95% confidence interval [CI]: 94%, 97%) was significantly higher than sensitivity of ultrasonography (US) (81%; 95% CI: 75%, 87%) and magnetic resonance (MR) imaging (85%; 95% CI: 66%, 95%). There were no significant differences in specificity among cholescintigraphy (90%; 95% CI: 86%, 93%), US (83%; 95% CI: 74%, 89%) and MR imaging (81%; 95% CI: 69%, 90%). Only one study about evaluation of computed tomography (CT) met the inclusion criteria; the reported sensitivity was 94% (95% CI: 73%, 99%) at a specificity of 59% (95% CI: 42%, 74%). CONCLUSION Cholescintigraphy has the highest diagnostic accuracy of all imaging modalities in detection of acute cholecystitis. The diagnostic accuracy of US has a substantial margin of error, comparable to that of MR imaging, while CT is still underevaluated.

Abstract
Cholelithiasis is a prevalent condition in Western populations. Most cases are asymptomatic but complications can occur. Acute cholangitis, cholecystitis, and gallstone pancreatitis are the most common biliary tract emergencies and are usually caused by biliary calculi. Whenever possible, acute cholecystitis should be treated with early LC. AAC is an uncommon condition usually affecting patients with significant comorbidities. Treatment is usually with percutaneous cholecystostomy, which often is also the only required therapy. Endoscopic drainage is the preferred form of biliary decompression in acute cholangitis and these patients should subsequently undergo elective LC unless unfit for surgery. Effective and optimal management of biliary tract emergencies relies on close cooperation between gastroenterologist, surgeon, and radiologist.

Abstract
Experience in the treatment of acute cholecystitis with percutaneous cholecystostomy in 29 high-risk and elderly patients is reported. The treatment group included 14 men and 15 women, 21 of whom were over 70 years of age. The suspected clinical diagnosis of acute cholecystitis was confirmed in all cases by ultrasonography (accuracy: 95.6%). The percutaneous cholecystostomy was successful in 27 of 29 cases and these patients had a sudden improvement in their clinical condition; failure of the procedure was due in one patient to dislodgement of the catheter and in another patient to the guide-wire slipping out of the gallbladder. Six patients complained of pain radiating to the right shoulder which disappeared within 30-60 minutes after the procedure. Twenty-three of the 27 patients subsequently underwent elective cholecystectomy. In 22 patients the ultrasonographic findings were compared with the histology; thus enabling us to establish an ultrasonographic staging of acute cholecystitis related to the seriousness of the disease. Percutaneous cholecystostomy is the treatment of choice in high-risk patients, in the elderly, as well as in young patients with impending perforation.

Abstract
99mTc-HMPAO labeled leukocyte scanning was performed on 38 patients with clinically suspected acute cholecystitis (AC) to evaluate its diagnostic value. The typical finding was an increasing accumulation of the tracer in the gallbladder wall in a 4 hour series of scintigrams. Leukocyte scan was positive in 16 of 17 patients with surgically and histologically confirmed AC. There were no false-positive findings. The sensitivity, specificity, and accuracy of scintigraphy were 94, 100, and 96%, respectively. In 2 patients with acute acalculous cholecystitis true-positive findings were observed. Scintigraphy with 99mTc-HMPAO labeled leukocytes is a valuable new imaging method in AC.

Abstract
Acute cholecystitis is a frequent consideration in patients presenting to the emergency department with the challenging complaint of upper abdominal pain. It is estimated that 20% of American adults have gallstones, and of these a large percentage (about one-third) will at some point develop acute cholecystitis. The epidemiology and associated risk factors of acute cholecystitis are briefly reviewed along with the pathogenesis and clinical presentation of the disease. Finally, an approach to the diagnosis in the emergency department and suggested management is discussed including a comparison of the strengths and weaknesses of ultrasonography and hepatobilary scintigraphy.
