Background Gastric schwannomas (Gs) are rare mesenchymal neoplasms of the gastrointestinal tract. Diagnosis is commonly achieved by pathological examination of resected specimen. In most cases surgical resection of submucosal gastric lesions is performed with wide margins. New minimally invasive techniques are described in an increasing number of cases. Methods A Pubmed, Cochrane and Embase systematic review of the literature has been performed. Original papers, review articles, case reports published between 1988 and 2019 were considered eligible. Only papers written in English with full text available have been included. Articles reporting a follow up period, the type of treatment of the primary tumor and the appearance of local or distant recurrence were compared and analysed. Statistical analysis of data has been performed using GraphPad Prism 7 software. Results 328 articles were found and a total of 102 were included in the analysis. Fifty-three papers reported the follow-up information, ranging from 1-417 months across different studies. Among them, 31 patients underwent endoscopic removal of the gastric lesions, 140 patients local surgery, including wedge resection or partial gastrectomy and 148 patients underwent subtotal or total gastrectomy. The median follow-up was of 27-38-33 months respectively. No recurrence or distant metastasis were detected in endoscopic group. Among local surgery group, liver metastasis was reported in one case; in extended surgery group one patient died for multiple liver metastases. Conclusions In comparison with endoscopic group, local or more extended surgery involved a larger cohort of patients and reported satisfactory long-term results. Surgical approach in absence of a definite pre-operative diagnosis is considered the gold standard treatment for resectable Gs due to the excellent long-term outcome. Further studies are warranted to define the role of endoscopic treatment. Keywords : Schwannoma, neurinoma, gastric neurinoma, gastric schwannoma.
