The purpose of this study is to evaluate the effectiveness and safety of drainage of abdominal abscesses with small-bore (6F and 9F) drains.<\/jats:p><\/jats:sec>Material and methods<\/jats:title>The analysis of a prospectively maintained database included 135 consecutive patients from a single centre with abdominal or pelvic abscesses, who underwent CT-guided drainage. Procedures were performed using a one-step trocar technique with 6F (40 procedures) or 9F (95 procedures) catheters. Technical success was defined as insertion of the drain into the abscess cavity and aspiration of the fluid sample. Clinical success was defined as resolution of infection without surgical intervention or upsizing of the drain.<\/jats:p><\/jats:sec>Results<\/jats:title>The mean size of abscesses was 77.0 \u00b1 28.8 mm (32-220 mm). Thick fluid was aspirated from 129 collections; 6 collections contained thin fluid. Technical success was achieved in 100% of procedures. Clinical success was achieved in 94.8% of patients. Surgical drainage was necessary in 3.7% of patients and upsizing in 1.5% of patients. Complications of Clavien-Dindo grade III were noted in 2.2% of patients without grade IV or V adverse events. The mean radiation dose in terms of Dose Length Product was 617 \u00b1 467 mGy x cm. The mean procedure time was 28.0 \u00b1 11.3 min.<\/jats:p><\/jats:sec>Conclusions<\/jats:title>CT-guided drainage of abdominal abscesses with small- and very small-bore drains is usually sufficient to obtain clinical success with a low complication rate in the case of thick fluid collections.<\/jats:p><\/jats:sec>","DOI":"10.5114\/pjr.2024.136420","type":"journal-article","created":{"date-parts":[[2024,3,22]],"date-time":"2024-03-22T08:14:16Z","timestamp":1711095256000},"page":"156-160","source":"Crossref","is-referenced-by-count":5,"title":["Effectiveness and safety of CT-guided drainage of abdominal abscesses with small and extra-small-bore drains: a\u00a0single-centre observational study"],"prefix":"10.5114","volume":"89","author":[{"given":"Grzegorz","family":"Rosiak","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jakub","family":"Franke","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Krzysztof","family":"Milczarek","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dariusz","family":"Konecki","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Emilia","family":"Wnuk","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"3061","published-online":{"date-parts":[[2024,3,19]]},"reference":[{"key":"ref-1161199","doi-asserted-by":"crossref","first-page":"862","DOI":"10.1177\/000313481107700720","article-title":"Differences in morbidity and mortality with percutaneous versus open surgical drainage of postoperative intra-abdominal infections: a review of 686 cases","volume":"77","author":"Politano AD","year":"2011","unstructured":"Politano AD, Hranjec T, Rosenberger LH, et al.
