Abstract

Background Endoscopic submucosal dissection (ESD) is now considered the standard treatment for early gastric cancer (EGC). However, the widespread adoption of ESD in western countries has been slow. We performed a systematic review to evaluate short-term outcomes of ESD for EGC in non-Asian countries. Methods We searched 3 electronic databases from inception until October 26, 2022. Primary outcomes were en bloc, R0 and curative resections rate by region. Secondary outcomes were overall complications, bleeding, and perforation rate by region. The proportion of each outcome, with the 95% confidence interval (CI), was pooled using a random-effects model with the Freeman-Tukey double arcsine transformation. Results Twenty-seven studies from Europe (n=14), South America (n=11) and North America (n=2) were included, involving 1875 gastric lesions. Overall, en bloc, R0, and curative resection rates were achieved in 96% (95%CI 94-98%), 85% (95%CI 81-89%), and 77% (95%CI 73-81%) of cases, respectively. Considering only information from lesions with adenocarcinoma, the overall curative resection was 75% (95CI 70-80%). Bleeding and perforation were observed in 5% (95%CI 4-7%) and 2% (95%CI 1-4%) of cases, respectively. Conclusion Our results suggest that short-term outcomes of ESD for the treatment of EGC are acceptable in non-Asian countries.
