Abstract
Background:
Ultrasound (US)- or computed tomography-guided drainage for abdominal abscess is currently the first-line options for drainage, but both options have disadvantages. Patients without adequate windows for drainage mostly undergo surgical drainage. However, surgical drainage is invasive and expensive. Endoscopic US (EUS)-guided drainage is a minimally invasive alternative for abdominal abscess, but there is less consensus on its efficacy, safety and complications. This meta-analysis aims to evaluate EUS-guided drainage for abdominal abscess.
Materials and Methods:
We retrieved relevant papers on EUS-guided drainage for abdominal abscess from the PubMed, Cochrane Library, Web of Science and EMBASE databases. Each paper was reviewed, and data were extracted. We used R software version 3.6.3 to perform the meta-analysis. Fixed effects models were used for merging data.
Results:
A total of 11 papers met the inclusion criteria, with a total sample population of 264 patients. The meta-analysis showed that the pooled clinical success rate was 90% (95% confidence interval [CI], 0.85–0.95), the technical success rate was 99% (95% CI, 0.97–1.00) and the recurrence rate was 1% (95% CI, 0.00–0.03). Three studies reported the complications, including perforation, bleeding and stent migration; none of the other eight studies reported complications. There were no significant differences between subgroups. There was no publication bias in either the clinical or the technical success rates.
Conclusions:
This meta-analysis showed that EUS-guided drainage for abdominal abscess was effective and safe, with an excellent technical success rate. In addition, EUS-guided drainage could be used for abscesses with complex anatomy. Nevertheless, complications and stent type should be considered.
