    Abstract:
    OBJECTIVE: A comprehensive meta-analysis was performed to evaluate the efficacy and safety of endoscopic ultrasound-guided gastroenterostomy (EUS-GE) for benign and malignant gastric outlet obstruction (GOO). MATERIAL AND METHODS: PubMed, Embase, Web of Science and Cochrane Library were searched to identify relevant studies. The primary outcomes evaluated technical success, clinical success, and adverse events (AEs). RESULTS: Twenty‑six studies with 1493 patients were included in this meta-analysis. The pooled rates of technical success, clinical success, and overall AEs of EUS-GE were 94.0%, 89.9%, and 13.1%, respectively. Eight studies were included in the subgroup meta-analysis for comparative evaluation of EUS-GE and surgical gastroenterostomy (SGE), while seven studies were for EUS-GE and enteral stenting (ES). Compared with SGE, the pooled odds ratios (ORs) of technical success, clinical success, and overall AEs of EUS-GE were 0.17 (p = .003), 1.42 (p = .40), and 0.15 (p < .00001), respectively. When compared with ES, the above corresponding pooled ORs were 0.55 (p = .11), 2.64 (p < .0001), and 0.41 (p = .01), respectively. CONCLUSION: Although it is technically challenging, this largest meta-analysis indicates that EUS‑GE has comparable and high technical and clinical success rates and hence a very effective minimally invasive procedure for GOO.
