Abstract Background and aims Gastric schwannoma (GS) is not well clinically recognized and surgical resection (SR) remains the mainstay of treatment. Recently, endoscopic resection (ER) appears to be a safe and effective alternative. However, its comparative outcomes with SR is lacking. Our aim was to first compare clinical outcomes and costs between ER and SR in the management of GSs. Methods A total of 46 consecutive patients with GSs who underwent ER (n = 16) or SR (n = 30) in our large tertiary center between July 2007 and Oct 2018 were included. Clinicopathologic features, clinical outcomes, medical costs and follow-up were retrospectively reviewed and compared between two groups. Results Baseline characteristics are comparable except for a smaller tumor size in ER group (22.9 vs 41.0 mm, p = 0.002). Complete resection was achieved in 87.5% of patients with ER and 100% of patients with SR (p = 0.116). The ER group had a significant shorter operative time (91.6 vs 128.2 min), less blood loss (16.9 vs 62.7 mL) and lower operation cost (21,054.4 vs 30,843.4 RMB) than SR group (all p
