- Abstract
Background: There is a significant variability in the reported outcomes following endovascular embolization of arterial pseudoaneurysms in pancreatitis. The objective of this systematic review and meta-analysis is to evaluate the efficacy of endovascular embolization of pancreatitis-related pseudoaneurysms., Methods: Searches of MEDLINE, EMBASE, and SCOPUS databases were performed through July 1, 2019 in accordance with PRISMA guidelines. All studies with ≥10 patients reporting technical success, clinical success, complications, and mortality were included. Generalized linear mixed method with random effects model was used for assessing pooled incidence rates and corresponding 95% confidence intervals (CIs)., Results: A total of 29 studies (n = 840 with 638 pseudoaneurysms) were included. The pooled incidence rates of pseudoaneurysms in acute and chronic pancreatitis were 0.05% and 0.03%, respectively (odds ratio, 0.91, 95% CI-0.24-3.43). The most common site of pseudoaneurysm was splenic artery (37.7%). The most common embolization agent was coil (n = 415). The follow up period was 54.7 months (range, 21 days to 40.5 months). Pooled technical success rate was 97% (95% CI-92-99%, I
2 83%). Clinical success rates at ≤3 months, 3-12 months, and >12 months were 82% (95% CI-70-90%, I2 42%), 86% (95% CI-75-92%, I2 44%), and 88% (95% CI-83-91%, I2 0%), respectively. There was no significant difference in the technical or clinical success between acute and chronic pancreatitis on subgroup analysis. Mortality was lower in chronic pancreatitis (OR 4.27 (95% CI 1.35-13.53, I2 0%)). Splenic infarction was the most common complication (n = 47)., Conclusion: Endovascular embolization is associated with a high technical and clinical success., Competing Interests: Declaration of competing interest None., (Copyright © 2020 IAP and EPC.
