A systematic review and meta-analysis were performed to compare the outcomes of LAMS alone and LAMS with coaxial DPPS placement in the management of PFCs.Methods: A systematic review was conducted to identify studies comparing LAMS and LAMS\/DPPS for PFC drainage. Primary outcomes included the rate of clinical success, overall adverse events (AEs), bleeding, infection, occlusion, and stent migration. The pooled effect size was summarized using a random-effects model and compared between LAMS and LAMS\/DPPS by calculating odds ratios (ORs).Results: Nine studies involving 709 patients were identified (338 on LAMS and 371 on LAMS\/DPPS). LAMS\/DPPS was associated with a reduced risk of stent obstruction (OR, 0.59; p=0.004) and infection (OR, 0.55; p=0.001). No significant differences were observed in clinical success (OR, 0.96; p=0.440), overall AEs (OR, 0.57; p=0.060), bleeding (OR, 0.61; p=0.120), or stent migration (OR, 1.03; p=0.480).Conclusions: Coaxial DPPS for LAMS drainage of PFCs is associated with a reduced risk of stent occlusion and infection; however, no difference was observed in the overall AE rates or bleeding.<\/jats:p>","DOI":"10.5946\/ce.2023.297","type":"journal-article","created":{"date-parts":[[2024,7,24]],"date-time":"2024-07-24T07:44:25Z","timestamp":1721807065000},"page":"595-603","update-policy":"https:\/\/doi.org\/10.5946\/crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Coaxial
