Abstract: With the widespread adoption of endoscopy and laparoscopy in the treatment of gastric cancer, the pivotal role of endoscopy in ensuring the quality of laparoscopic surgery has grown increasingly significant. Simultaneously, the complementary and collaborative role of laparoscopy in the endoscopic treatment of gastric cancer has garnered attention. The dual-endoscopic treatment model represents an inevitable trend in the evolution of precise and personalized healthcare. Currently, the fusion of endoscopy and laparoscopy manifests in diverse and multifaceted ways. The integration of dual‑endoscopy necessitates transcending the boundaries between internal and surgical disciplines. The collaborative multidisciplinary platform‑the Digestive Disease Center, centered on disease treatment, can streamline the diagnostic and treatment process, making it efficient, safe, and rational. This, in turn, allows dual‑endoscopy to truly realize synergy and cooperation, leading to more precise, minimally invasive procedures, and maximal functional preservation in the treatment of gastric cancer. The authors elucidate the combined strategy of endoscopy and laparoscopy, aiming to establish a more rational dual‑endoscopic diagnostic and treatment model for patients with gastric cancer.
