胃癌保功能手术中双镜联合技术应用价值及评价OA

In the transformation of gastric cancer surgery from traditional radical resection to emphasizing both radicality and function preservation,laparo-endoscopic combined surgery(LECS)has become a core supporting technique for function-preserving gastrectomy in early gastric cancer due to its advantages of precise localization,minimal invasiveness and controllable safety.Endoscopy enables precise lesion localization,boundary marking,mucosal dissection and intraluminal exposure,while laparoscopy achieves safe resection,lymph node evaluation,gastric wall defect repair and intra-abdominal exploration.The synergistic effect of the two modalities effectively resolves the contradictions among lesion localization,resection safety,function preservation and radical guarantee faced by single minimally invasive technique,significantly reduces perioperative complications,accelerates postoperative recovery,and improves long term quality of life.With strict adherence to appropriate indications,standardized procedural protocols,and enhanced multidisciplinary collaboration,it can achieve oncological outcomes comparable to those of standard radical gastrectomy.As the technique continues to be optimized and the clinical evidence matures,combined laparoscopic and endoscopic function-preserving surgery is expected to play an increasingly important role in the management of early gastric cancer,offering patients less surgical trauma and better quality of life.
