The surveys covered institutional characteristics, surgical case volumes, procedure preferences for early gastric cancer by tumor location, and emerging topics such as robot\u2010assisted surgery and sentinel node navigation surgery. Statistical analysis included Fisher's exact test and residual analysis for changes in procedure selection over time.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The results indicate a marked shift toward laparoscopic and robot\u2010assisted gastrectomy, alongside a rise in function\u2010preserving procedures, particularly proximal gastrectomy and small remnant distal gastrectomy. However, procedures like pylorus\u2010preserving gastrectomy and vagus nerve preservation, and total gastrectomy with jejunal pouch reconstruction remain underutilized due to concerns regarding unclear benefits, technical complexity, and oncological safety.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>This study underscores advancements in minimally invasive and function\u2010preserving gastrectomy procedures in Japan but emphasizes the need for more robust clinical evidence to support the broader adoption of certain procedures. Future research, guided by emerging evaluation tools, is crucial for optimizing surgical outcomes and enhancing QOL for gastric cancer
