Despite the rapid proliferation of I-EUS research, a comprehensive bibliometric analysis characterizing the global intellectual architecture of this field is lacking. Methods: A Web of Science Core Collection search identified 4340 records, of which 2237 were included (2001\u20132024), analyzed with R bibliometrix (version 5.0) and VOSviewer (version 1.6.20). Results: Publication output demonstrated three distinct phases with pronounced acceleration from 2017. The United States led global output (n = 625, 27.9%), followed by Japan (n = 435, 19.4%) and Italy (n = 166, 7.42%). At the continental level, Asia collectively produced the largest share of output (n = 884, 39.5% of the total corpus), exceeding the Americas (n = 687, 30.7%) and Europe (n = 492, 22.0%). Gastrointestinal Endoscopy was the most productive journal (n = 173). Tokyo Medical University was the most productive institution (n = 93, 4.16%). Four thematic clusters were identified: EUS-guided biliary and pancreatic ductal drainage; diagnostic, ablative, and injection EUS for pancreatic tumors; LAMS-enabled luminal bypass and gallbladder drainage; and pancreatic fluid collections and necrotizing pancreatitis. Temporal overlay confirmed EUS-guided gastroenterostomy, EUS-guided gallbladder drainage, and EUS-guided radiofrequency ablation as the leading research frontiers. Annual output showed no discernible contraction during the COVID-19 pandemic period (2020\u20132021). Conclusions: The United States led global I-EUS research output with higher rates of international collaboration compared with East Asian nations, although Asia as a continent generated the largest aggregate volume of publications. EUS-guided biliary drainage and pancreatic fluid collection management constitute the established, high-volume core of the field, while EUS-guided gastroenterostomy and novel ablative technologies represent the most dynamic investigative frontiers.<\/jats:p>","DOI":"10.3390\/clinpract16080153","type":"journal-article","created":{"date-parts":[[2026,8,20]],"date-time":"2026-08-20T08:10:20Z","timestamp":1787213420000},"page":"153","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Interventional Endoscopic Ultrasound in Gastroenterology: A Comprehensive Bibliometric Analysis (2001\u20132024)"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8134-8524","authenticated-orcid":false,"given":"Koji","family":"Takahashi","sequence":"first","affiliation":[{"name":"Department of Gastroenterology, Eastern Chiba Medical Center, 3\u20136\u20132 Okayamadai, Togane 283-8686, Japan"},{"name":"Department of General Medical Science, Graduate School of Medicine, Chiba University, 1\u20138\u20131 Inohana, Chiba 260-8670, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Noa","family":"Minami","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology, Eastern Chiba Medical Center, 3\u20136\u20132 Okayamadai, Togane 283-8686, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kohei","family":"Horie","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology, Eastern Chiba Medical Center, 3\u20136\u20132 Okayamadai, Togane 283-8686, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-0938-351X","authenticated-orcid":false,"given":"Taiga","family":"Sudo","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology, Eastern Chiba Medical Center, 3\u20136\u20132 Okayamadai, Togane 283-8686, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nana","family":"Yamada","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology, Eastern Chiba Medical Center, 3\u20136\u20132 Okayamadai, Togane 283-8686, Japan"},{"name":"Department of General Medical Science, Graduate School of Medicine, Chiba University, 1\u20138\u20131 Inohana, Chiba 260-8670, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Terunao","family":"Iwanaga","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology, Eastern Chiba Medical Center, 3\u20136\u20132 Okayamadai, Togane 283-8686, Japan"},{"name":"Department of General Medical Science, Graduate School of Medicine, Chiba University, 1\u20138\u20131 Inohana, Chiba 260-8670, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Takafumi","family":"Sakuma","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology, Eastern Chiba Medical Center, 3\u20136\u20132 Okayamadai, Togane 283-8686, Japan"},{"name":"Department of General Medical Science, Graduate School of Medicine, Chiba University, 1\u20138\u20131 Inohana, Chiba 260-8670, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2238-9558","authenticated-orcid":false,"given":"Hidehiro","family":"Kamezaki","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology, Eastern Chiba Medical Center, 3\u20136\u20132 Okayamadai, Togane 283-8686, Japan"},{"name":"Department of General Medical Science, Graduate School of Medicine, Chiba University, 1\u20138\u20131 Inohana, Chiba 260-8670, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,8,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"898","DOI":"10.1055\/s-2001-17324","article-title":"Endoscopic ultrasound-guided bilioduodenal anastomosis: A new technique for biliary drainage","volume":"33","author":"Giovannini","year":"2001","journal-title":"Endoscopy"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"1209","DOI":"10.1136\/gutjnl-2017-314341","article-title":"Consensus guidelines on the optimal management in interventional EUS procedures: Results from the Asian EUS group RAND\/UCLA expert panel","volume":"67","author":"Teoh","year":"2018","journal-title":"Gut"},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"246","DOI":"10.1067\/mge.2003.85","article-title":"EUS-cholangio-drainage of the bile duct: Report of 4 cases","volume":"57","author":"Burmester","year":"2003","journal-title":"Gastrointest.
