Background Gastric cancer management remains fraught with high morbidity and mortality rates owing to surgical interventions. Postoperative complications and extended hospitalisation profoundly affect patient survival, with elderly and medically compromised patients facing greater risks. We hypothesised that regional anaesthesia may reduce the surgical stress response and thus mortality. Hence, this study was aimed at investigating whether adjunctive application of regional anaesthesia during gastric cancer surgery attenuates the stress response to surgery, thereby improving postoperative survival outcomes.

超越疼痛控制：探索区域麻醉提高胃癌手术存活率的潜力：一项回顾性队列研究

背景由于手术干预，胃癌治疗仍然充满高发病率和死亡率。术后并发症和延长住院时间严重影响患者的生存，老年和病情严重的患者面临更大的风险。我们假设局部麻醉可能会降低手术应激反应，从而降低死亡率。因此，本研究旨在调查胃癌手术期间辅助使用区域麻醉是否可以减轻手术应激反应，从而改善术后生存结果。
