早期胃癌双镜联合前哨淋巴结导航手术多学科临床诊疗实践专家共识（2025版）

Expert consensus on the multidisciplinary clinical practice of laparoscopic‑endoscopic cooperative surgery combined with sentinel lymph node navigation surgery for early gastric cancer (2025 edition)

摘要:

随着手术技术的进步与早期胃癌诊疗水平的提升，微创化与功能保留已成为患者和医师的共同目标。双镜联合前哨淋巴结导航手术（laparoscopic‑endoscopic cooperative surgery combined sentinel lymph node navigation surgery，LECS‑SNNS）因兼具微创和功能保留的双重优势而备受关注，但目前尚缺乏充分的循证医学证据来指导其临床实践。经系统梳理LECS‑SNNS在早期胃癌临床应用方面的相关研究证据，结合专家意见，最终形成20条推荐意见。内容涵盖术前评估、外科手术操作、术中内镜操作、病理诊断、术后处理及随访等关键环节。共识旨在为LECS‑SNNS的规范应用和推广提供全面的指导建议，以期推动早期胃癌的精准化、微创化与保功能治疗。

Abstract:

With the advancement of surgical techniques and the improvement of the diagnosis and treatment of early gastric cancer, minimally invasive and function-preserving approaches have become the common goal of both patients and physicians. Laparoscopic-endoscopic cooperative surgery combined with sentinel lymph node navigation surgery (LECS-SNNS) has attracted much attention due to its dual advantages of minimal invasion and functional preservation, but there is still a lack of sufficient evidence-based medical evidence to guide its clinical practice at present. Therefore, this consensus systematically reviewed the relevant research evidence on the clinical application of LECS-SNNS for early gastric cancer, and combined with expert opinions, ultimately formulated 20 recommendations, including preoperative assessment, surgical procedure, intraoperative endoscopic procedure, pathological diagnosis, postoperative management, and follow‑up. This consensus is aimed to provide comprehensive guidance and suggestions for standardized application and promotion of LECS‑SNNS, with the goal of promoting precise, minimally invasive and function-preserving treatment for early gastric cancer.
