Endoscopic submucosal dissection for early gastric cancer: A review of comparative perspectives on treatment outcomes vs gastrectomy

Table 1 Comparison of key perioperative indicators between endoscopic submucosal dissection and conventional gastrectomy

Key performance indicators	ESD group	Conventional gastrectomy group	Statistical results	Conclusion
Overall treatment success rate	92.86%	Slightly lower	χ² = 2.293, P > 0.05	There was no statistically significant difference between the two groups
Incidence of complications	5.56%	13.27%	P < 0.05	The ESD group offers superior safety
Intraoperative blood loss	Less	More	-	The ESD group is superior
Duration of the operation	Shorter	Longer	-	The ESD group is superior
Recovery time after oral administration	2.43 days	Longer	-	The ESD group is superior
