功能保留性胃切除术，尤其是保留幽门及迷走神经胃部分切除术（PPG）可以提高胃癌患者术后的生活质量，得到了学术界的广泛认可。随着外科技术和设备的发展，保留神经已成为"精准医疗"时代的新要求，但在胃癌手术中，对迷走神经腹腔支的保留一直存在争议。目前的研究已经表明，保留迷走神经的腹腔支在早期胃癌患者中是安全可行的。保留腹腔支在胃癌手术中的价值虽有争议，但在预防胆结石、调节胃排空、减少倾倒综合征、缓解慢性腹泻、减少胃食管反流及抑制胆汁反流方面可能发挥一定作用。随着外科手术进入个体化精准治疗时代，迷走神经腹腔支在胃癌手术中的意义值得在未来进一步关注和探索，以推动功能保留性胃切除术的发展，提高患者的生活质量。

Function-preserving gastrectomy, especially pylorus-preserving gastrectomy (PPG), can improve the quality of life and has been widely recognized. With the development of surgical techniques and equipment, nerve preservation has become a new requirement in the era of "precision medicine", but the preservation of celiac branch of the vagal nerve remains controversial in gastric cancer surgery. Current researches have shown that the preservation of celiac branch of the vagal nerve is safe and feasible in patients with early gastric cancer. Although controversial, nerve preservation may play a role in preventing gallstones, regulating gastric emptying, reducing dumping syndrome, alleviating chronic diarrhea, reducing gastroesophageal reflux, and inhibiting bile reflux. The significance of the celiac branch of the vagal nerve in gastric cancer surgery is worth further attention and exploration to promote the development of function-preserving gastrectomy and improve the quality of life of patients.
