Basic Information

Recruitment status	Recruiting
Health condition(s) or Problem(s) studied	gastric tumor
Date of first enrollment	08/10/2025
Target sample size	30
Countries of recruitment
Study type	Interventional
Intervention(s)	The procedure will be performed using the E-LOC method, which involves closure with standard clips, a 2 cm ring-shaped surgical suture, and an O-ring typically used for hemostasis of esophageal varices. Closure with clips will be considered complete when no cavity formation is observed and the wound is entirely covered (i.e., complete closure as defined).

Outcome(s)

Primary Outcome	Complete closure rate after gastric ESD
