Core Tip

Core tip: Endoscopic submucosal dissection (ESD) has become the preferred approach to remove larger or advanced gastrointestinal lesions in Asian countries. However, there might be regional differences in outcomes since the majority of ESD publications come from the Eastern world. To provide such information we conducted a systematic review and meta-analysis comparing ESD outcomes for different regions of the world. This study found that there are indeed regional differences for ESD outcomes. Eastern countries had better curative, en bloc and R0 resection rate than Western countries as well as less perforation requiring surgery.
