Adverse events in endoscopic ultrasound-guided choledochoduodenostomy with lumen-apposing metal stents: A systematic review and meta-analysis

Jia-Su Li et al. J Gastroenterol Hepatol. 2024 Sep.

Abstract

Background and aim: Several meta-analyses have analyzed the technical and clinical success of endoscopic ultrasound-guided choledochoduodenostomy (EUS-CDS) by using lumen-apposing metal stents (LAMS) in malignant biliary obstruction, but those concerning adverse events (AEs) are scarce. The current systematic review and meta-analysis was conducted to evaluate the AEs after EUS-CDS with LAMS.

Methods: A comprehensive literature search of PubMed, Embase, Scopus, Web of Science, and the Cochrane Library was conducted for studies reporting the outcomes of EUS-CDS with LAMS. The main endpoints were the incidence of overall and specific AEs. Moreover, the stent dysfunction, and reintervention rates were evaluated independently.

Results: A total of 21 studies (n = 1438) were included in the final meta-analysis. The pooled rate of technical and clinical success was 93.5% (95% confidence interval [CI]: 91.3-95.1) and 88.0% (95% CI: 83.9-91.1), respectively. After EUS-CDS with LAMS, the pooled incidence of overall AEs was 20.1% (95% CI: 16.0-24.9). The estimated rate of early AEs was 10.6% (95% CI: 7.9-14.2), and late AEs was 11.2% (95% CI: 8.2-15.2). Infection/cholangitis was the commonest AE, with a pooled incidence of 6.1% (95% CI: 3.7-10.1). The estimated incidence of stent dysfunction and reintervention was 10.5% (95% CI: 7.5-14.4), and 12.1% (95% CI: 9.3-15.7), respectively.

Conclusion: Despite with a high technical and clinical success rate, EUS-CDS with LAMS may be associated with overall AEs and stent dysfunction in one-fifth and one-tenth of cases, respectively. Further efforts are required to optimize its safety and long-term stent patency.
