The pocket-creation method for gastric tumors matches conventional techniques in safety and effectiveness, with fewer subsequent surgeries.

• Adverse event rates: 14.3% for pocket-creation vs. 12.9% for conventional.
• Significantly lower need for further surgery in pocket-creation group (2.9% vs. 12.9%, p=0.028).

Consider using the pocket-creation method to reduce follow-up interventions while achieving comparable resection rates.

• Procedure times are similar: 56.8 min for pocket-creation vs. 59.7 min for conventional.
