The aim of this study was to compare DFI-EUS with contrast-enhanced EUS (CE-EUS) for the evaluation of vascularization in solid pancreatic lesions.</p><p><strong>Methods: </strong>We included patients who had a pancreatic mass visualized by EUS, with recorded images of their assessment in DFI-EUS and CE-EUS techniques and a histological diagnosis confirmed malignant tumors or a minimum of 1-year follow-up for benign lesions.</p><p><strong>Results: </strong>Of the 107 patients included in this retrospective single-center study, the histological diagnosis revealed 69 cases (64.5%) of pancreatic adenocarcinoma, 18 cases (16.8%) of neuroendocrine tumors (NETs), and 10 cases (9.3%) of metastases from nonpancreatic cancers. A smaller proportion (9.4%) exhibited other lesions. As a result, the incidence of intralesional microvascularization was 43.9% with DFI-EUS and 48.6% with CE-EUS, indicating a positive correlation between the 2 techniques (<i>P</i> = 0.0001). Compared to CE-EUS, DFI-EUS exhibited sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of 88.5%, 98.2%, 97.9%, and 90%, respectively, for the detection of intralesional vessels.</p><p><strong>Conclusions: </strong>The novel technique DFI-EUS demonstrates a remarkable correlation with CE-EUS, exhibiting high sensitivity and specificity for the assessment of microvascularization in solid pancreatic lesions. This method eliminates the need for a contrast agent, thus carrying no risk of adverse effects.</p>","PeriodicalId":11577,"journal":{"name":"Endoscopic Ultrasound","volume":"13 4","pages":"248-252"},"PeriodicalIF":4.4,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11419480/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142343822","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The clinical outcomes of EUS-HGS are not well studied because of variability in procedure technique. We conducted a search of multiple electronic databases and conference proceedings from inception through January 2023. The clinical outcomes studied were pooled technical success, clinical success, and adverse events. Standard meta-analysis methods were used using the random-effects model, and heterogeneity was studied by <i>I</i> ² statistics. We analyzed 44 studies, which included 19 prospective and 25 retrospective studies. The pooled technical success rate of EUS-HGS was 94.4% (confidence interval [CI], 92.4%-95.9%; <i>I</i> ² = 0%), and the pooled clinical success rate was 88.6% (CI, 83.7%-92.2%; <i>I</i> ² = 0%). The pooled adverse outcomes with EUS-HGS were 23.8% (CI, 19.6%-28.5%; <i>I</i> ² = 0%). The mild adverse event rate associated with HGS was 5.8% (4.2%-8.1%; <i>I</i> ² = 0%), moderate adverse event rate was 12.1% (9.1%-15.8%; <i>I</i> ² = 16%), and severe adverse event rate was 4.2% (3.0%-5.7%; <i>I</i> ² = 61%), whereas fatal adverse event rate was 3.2% (1.9%-5.4%; <i>I</i> ² = 62%). On subgroup analysis, the pooled rate of adverse events of EUS-guided hepaticogastrostomy with antegrade stenting was 13.3% (95% CI, 8.2%-21.0%). The pooled technical success with EUS-guided hepaticogastrostomy with antegrade stenting was 89.7% (95% CI, 82.6%-94.2%), and clinical success was 92.5% (95% CI, 77.9%-97.7%). On the basis of our analysis of EUS-HGS, the overall technical success was 94.4%, and the clinical success rate was 88.6%, and the overall adverse events were reported to be 23.8%.
