Purpose: Endoscopic drainage is an established treatment modality for adult patients with pancreatic fluid collections (PFCs). Available data regarding the efficacy and safety of endoscopic drainage in pediatric patients are limited. In this systematic review and meta-analysis, we aimed to analyze the outcomes of endoscopic drainage in children with PFCs. Methods: A literature search was performed in Embase, PubMed, and Google Scholar for studies on the outcomes of endoscopic drainage with or without endoscopic ultrasonography (EUS) guidance in pediatric patients with PFCs from inception to May 2021. The study’s primary objective was clinical success, defined as resolution of PFCs. The secondary outcomes included technical success, adverse events, and recurrence rates. Results: Fourteen studies (187 children, 70.3% male) were included in this review. The subtypes of fluid collection included pseudocysts (60.3%) and walled-off necrosis (39.7%). The pooled technical success rates in studies where drainage of PFCs were performed with and without EUS guidance were 95.3% (95% confidence interval [CI], 89.6–98%; I2=0) and 93.9% (95% CI, 82.6–98%; I2=0), respectively. The pooled clinical success after one and two endoscopic interventions were 88.7% (95% CI, 82.7–92.9%; I2=0) and 92.3% (95% CI, 87.4–95.4%; I2=0), respectively. The pooled rate of major adverse events was 6.3% (95% CI, 3.3–11.4%; I2=0). The pooled rate of recurrent PFCs after endoscopic drainage was 10.4% (95% CI, 6.1–17.1%; I2=0). Conclusion: Endoscopic drainage is safe and effective in children with PFCs. However, future studies are required to compare endoscopic and EUS-guided drainage of PFCs in children.
