Accuracy and efficacy of the endoscopic ultrasound (EUS) in diagnosing focal liver lesion (FLL), obtaining liver sampling and liver abscess drainage; A systematic review and meta-analysis
Bibliographic record
Abstract
Recently, there has been a surge in the clinical utilisation of endoscopic ultrasound (EUS) in hepatology [1]. These applications range from diagnosis to treatment of various liver diseases [2]. Therefore, the current systematic review has summarised the evidence on the diagnostic and therapeutic roles of EUS in liver diseases. PubMed, Medline, Cochrane Library, Web of Science, and Google Scholar databases were extensively scoured for studies until October 2023. The methodological quality of the eligible articles was performed using the Newcastle Ottawa Scale or Cochrane's Risk of Bias tool. In addition, statistical analyses were performed with the Comprehensive Meta-Analysis software. A total of 45 articles (28 evaluating the diagnostic role and 17 evaluating the therapeutic role of EUS) were included. The pooled analysis demonstrated that EUS diagnostic tests have an accuracy of 92.4% for focal liver lesions (FLL) and 96.6% for parenchymal liver diseases [Fig. 1]. In addition, the cumulative analyses showed that EUS-guided liver biopsies (EUS-LB) with either fine needle aspiration (FNA) or fine needle biopsy (FNB) have low complication rates when sampling FLL and parenchymal liver diseases (3.1% and 8.7%, respectively). Furthermore, analysis of data from four studies has shown that EUS-guided liver abscess (EUS-AD) has a high clinical (90.7%) and technical success (90.7%) without significant complications. Similarly, EUS-guided interventions for the treatment of gastric varices (GV) have a high technical success (98%) and GV obliteration rates (84%), with low complications (15%) and rebleeding events (17%) [Fig. 2]. EUS in liver diseases is a promising technique with the potential to be considered as a first-line therapeutic and diagnostic option in selected cases.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
