Summary
For metachronous early gastric cancer (EGC), endoscopic submucosal dissection (ESD) offers higher complete resection rates than endoscopic mucosal resection (EMR). ESD and surgery show similar outcomes for EGC resection.
Area of Science:
- Gastroenterology
- Surgical Oncology
- Endoscopy
Background:
- Early gastric cancer (EGC) management involves endoscopic submucosal dissection (ESD), endoscopic mucosal resection (EMR), and surgery.
- Optimal resection techniques for metachronous EGC after prior treatment remain unclear.
Conclusions:
- Endoscopic submucosal dissection (ESD) or surgery is preferred over endoscopic mucosal resection (EMR) for metachronous EGC.
- Choice of technique depends on local expertise and patient preference, primarily due to EMR's higher incomplete resection risk.
