Summary
Brief summary (as posted)
The main treatment for early gastric cancer (EGC) include endoscopic submucosal dissection (ESD) and radical gastrectomy. However, appropriate treatment for patients who exceed the absolute indications and noncurative resection of ESD remains unestablished. Sentinel node navigation surgery (SNNS) enables limited lymph node resection, thereby facilitating function-preserving gastrectomy (FPG) and improving quality of life (QoL). SNNS seems to be the promising solution according to previous study, however evidence-based medicine was lacking. It is imperative to establish its safety and efficacy in patients with EGC. However, the optimal implementation of FPG remain unclear. Moreover, objective assessment of postoperative functional outcomes,remains limited.

- description
- Laparoscopic-endoscopic cooperative surgery (LECS) offers a more targeted approach through the integration of the complementary strengths of endoscopy and laparoscopy. LECS enables accurate targeting, optimal resection margins and tissue sparing excision. Consequently, LECS better preserves gastric architecture and function, potentially leading to enhanced postoperative recovery and QoL. Nevertheless, current evidence supporting LECS for SNNS remains limited.

- D2 gastrectomy
- description
- A preoperative contrast-enhanced abdominal CT scan is conducted to assess the lesion's location, tumor dimensions, and lymph node metastasis (LNM). Preoperative endoscopic dye injection or intraoperative endoscopic localization is utilized to accurately identify the tumor site and ensure adequate resection margins. The extent of lymph node dissection (LND) adheres to the Japanese gastric cancer treatment guidelines 2023 (6th edition)\[4\]. Specifically, D2 distal gastrectomy encompasses lymph nodes No. 1, 3, 4sb, 4d, 5, 6, 7, 8a, 9, 11p, and 12a. D2 proximal gastrectomy includes nodes 1, 2, 3a, 4sa, 4sb, 7, 8a, 9, 11p, and 12a, while D2 total gastrectomy involves nodes 1, 2, 3, 4sa, 4sb, 4d, 5, 6, 7, 8a, 9, 11p, 11d, and 12a.
