Because endoscopic ultrasound-guided tissue acquisition (EUS-TA) allows tissue sample obtention from the digestive tract lumen, a biopsy without the intervention of ascites may prevent adverse events (AEs). This study aimed to evaluate the safety of EUS-TA for focal liver lesions in the presence of ascites.<\/jats:p><jats:p>\n            Patients and methods A retrospective study was conducted using medical records of cases in which EUS-TA was performed on focal liver lesions between 2016 and 2022. Study participants were classified into two groups: those with ascites and those without it, and the outcomes were compared. The primary outcome was AEs.<\/jats:p><jats:p>\n            Results We included 109 cases of EUS-TA for focal liver lesions. Ascites was present in 20.1% of cases (22\/109) and absent in 79.8% of cases (87\/109). There were no significant differences between the two groups in clinical backgrounds and EUS-TA procedure, although fine-needle biopsy needles were significantly more frequently used in patients without ascites. In the ascites group, puncture without intervening ascites was successful in 90.9% of cases (20\/22). The incidence of AEs was 4.5% (1\/22) in the ascites group and 1.1% (1\/87) in the non-ascites group, showing no significant difference. The two AEs were mild self-limiting abdominal pain.<\/jats:p><jats:p>\n            Conclusions In focal liver lesions with ascites, EUS-TA allows biopsy without the intervention of ascites in most cases. The incidence of AEs did not differ significantly between patients with and without ascites.<\/jats:p>","DOI":"10.1055\/a-2427-2427","type":"journal-article","created":{"date-parts":[[2024,9,30]],"date-time":"2024-09-30T22:59:03Z","timestamp":1727737143000},"page":"E1309-E1314","source":"Crossref","is-referenced-by-count":2,"title":["Endoscopic ultrasound-guided tissue acquisition for focal liver lesions can be safely performed in patients with ascites"],"prefix":"10.1055","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6803-9460","authenticated-orcid":false,"given":"Yuichi","family":"Takano","sequence":"additional","affiliation":[{"name":"Division of Gastroenterology, Department of Internal Medicine, Showa University Fujigaoka Hospital, Yokohama, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Naoki","family":"Tamai","sequence":"additional","affiliation":[{"name":"Division of Gastroenterology, Department of Internal Medicine, Showa University Fujigaoka Hospital, Yokohama, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Masataka","family":"Yamawaki","sequence":"additional","affiliation":[{"name":"Showa Daigaku Fujigaoka Byoin, Yokohama, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jun","family":"Noda","sequence":"additional","affiliation":[{"name":"Division of Gastroenterology, Department of Internal Medicine, Showa University Fujigaoka Hospital, Yokohama, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tetsushi","family":"Azami","sequence":"additional","affiliation":[{"name":"Division of Gastroenterology, Department of Internal Medicine, Showa University Fujigaoka Hospital, Yokohama, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2248-8655","authenticated-orcid":false,"given":"Fumitaka","family":"Niiya","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Showa University Fujigaoka Hospital, Yokohama, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fumiya","family":"Nishimoto","sequence":"additional","affiliation":[{"name":"Division of Gastroenterology, Department of Internal Medicine, Showa University Fujigaoka Hospital, Yokohama, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Naotaka","family":"Maruoka","sequence":"additional","affiliation":[{"name":"Division of Gastroenterology, Department of Internal Medicine, Showa University Fujigaoka Hospital, Yokohama, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tatsuya","family":"Yamagami","sequence":"additional","affiliation":[{"name":"Showa Daigaku Fujigaoka Byoin, Yokohama, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Masatsugu","family":"Nagahama","sequence":"additional","affiliation":[{"name":"Division of Gastroenterology, Department of Internal Medicine, Showa University Fujigaoka Hospital, Yokohama, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"194","published-online":{"date-parts":[[2024,11,18]]},"reference":[{"key":"ref1","doi-asserted-by":"crossref","first-page":"165","DOI":"10.1016\/S0168-8278(86)80075-7","article-title":"Complications following percutaneous liver biopsy.
