One patient had a walled-off necrotic collection from necrotizing pancreatitis; the other developed a postoperative abscess following appendectomy for perforated appendicitis. In each case, tract dilation was performed to accommodate the large-bore aspiration catheter, and follow-up CT imaging was used to assess treatment response.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>In both cases, the FlowTriever Aspiration Catheter enabled high-flow aspiration of solid and purulent material, with successful placement of large-bore drainage catheters. Follow-up imaging demonstrated marked reduction or near-complete collapse of the abscess cavities. No procedure-related complications were observed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Large-bore mechanical aspiration with the FlowTriever Aspiration Catheter may offer an effective adjunct or alternative to catheter upsizing and fibrinolytic therapy in patients with complex intra-abdominal abscesses, particularly when standard drainage techniques are unsuccessful. This approach may reduce the need for repeat interventions or surgical debridement in appropriately selected patients.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1007\/s00261-025-05178-2","type":"journal-article","created":{"date-parts":[[2025,8,23]],"date-time":"2025-08-23T06:28:40Z","timestamp":1755930520000},"page":"2148-2152","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Large-bore aspiration of complex intra-abdominal abscesses using a mechanical aspiration device"],"prefix":"10.1007","volume":"51","author":[{"given":"Gavin","family":"Wu","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Matthew","family":"Abad-Santos","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"David S.","family":"Shin","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eric J.","family":"Monroe","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jeffrey Forris Beecham","family":"Chick","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mina S.","family":"Makary","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2025,8,23]]},"reference":[{"issue":"3","key":"5178_CR1","doi-asserted-by":"publisher","first-page":"384","DOI":"10.1007\/s00270-021-03005-x","volume":"45","author":"M Abad-Santos","year":"2022","unstructured":"Abad-Santos M, Shin DS, Monroe EJ, Patel A, Gui SX, Chick JFB.
