探讨并总结经鼻空肠营养管置入技术在全达芬奇机器人胃癌根治术中的应用技巧及体会，以及置管过程中常见问题及解决方法。

收集2019年12月至2021年9月河北医科大学第四医院行全达芬奇机器人胃癌根治术中置入经鼻空肠营养管的192例患者资料，总结操作步骤，记录术中营养管置入时间、术后经管行肠内营养开始时间、首次排气时间、肠内营养并发症等情况。

192例患者中远端胃切除129例（均为毕Ⅱ式+Braun’s吻合），全胃切除39例（均为食管-空肠π式吻合），近端胃切除24例（均为空肠间置吻合），置管满意183例（95.31%），置管耗时（3.65±2.15）min，术后肠内营养开始时间为（16.59±2.43）h，首次排气时间为（3.26±1.52）d；除11例（5.73%）出现喂养不耐受外，181例（94.27%）耐受良好。

全达芬奇机器人下胃癌根治术中经鼻置入空肠营养管安全有效，整体上不影响手术时长，是早期开展肠内营养治疗的基础。

To summarize the application skills, experience, common problems and solutions in the process of naso-jejunal feeding tube placement in total da Vinci robotic radical gastrectomy.

192 cases with gastric cancer undergoing naso-jejunal feeding tube placement during total da Vinci robotic D2 radical gastrectomy in the Fourth Hospital of Hebei Medical University between December 2019 and September 2021 were reviewed. The time of naso-jejunal tube insertion, enteral nutrition through tube after operation, first exhaust, and the enteral nutrition-related complications were recorded.

129 cases underwent distal gastrectomy (Billroth’sⅡ+Braun’s anastomosis), 39 cases underwent total gastrectomy (esophageal jejunal π anastomosis), and 24 cases underwent proximal gastrectomy (jejunal interposition anastomosis). 183 cases were satisfied with catheterization, the average time of tube placement was (3.65±2.15) min, the time of enteral nutrition after operation was (16.59±2.43) h, and the time of first exhaust was (3.26±1.52) d. Except for 11 cases with feeding intolerance, the rest of the patients had good tolerance.

The placement of transnasal jejunal nutrition tube in total da Vinci robotic radical gastrectomy is safe and effective, which does not affect the length of operation as a whole, and is the basis for early enteral nutrition therapy.
