总结吸引器在机器人"3+2"辅助胃癌根治术中的应用体会。

回顾性分析2018年1~8月期间，甘肃省人民医院普外临床医学中心21例行机器人胃癌根治术患者的临床和手术资料。

本组患者平均年龄57.5岁，体质量指数22.4 kg/m²。术中，第二助手持肠钳进行手术视野大体的牵拉显露、第一助手持吸引器进行局部手术视野清理，协助手术进程。术前准备时间30~50 min，平均38.7 min；手术时间120~260 min，平均186.7 min；术中出血量30~120 ml，平均62.2 ml；淋巴结清扫数目562枚，平均26.7枚；术中损伤脾脏1例，是脾脏被膜撕裂，压迫止血，未切除脾脏，术中无严重并发症发生。

达芬奇机器人胃癌根治术中，尤其对于肥胖和进展期胃癌患者，达芬奇机器人"3+2"辅助是安全和实用的，利于新开展机器人胃癌手术的医师，可减轻开展的阻力，助手熟练使用吸引器可以提供良好的手术视野，降低手术难度，减少手术时间，更好的临床带教。

To summarize the application experience of aspirator in robot "3+ 2" assisted radical gastrectomy.

Retrospective analysis of clinical and surgical data of 21 patients with robotic radical gastrectomy in our department from Jan. to Aug. 2018.

The average age of this group of patients was 57.5 years old, and the body mass index was 22.4 kg/m². During the operation, the second assisted hand-held forceps were used to expose the surgical field, and the first assited hand-held suction device was used for local visual field cleaning to assist the operation process. The preoperative time was 30-50 minutes, with an average of 38.7 minutes; the operation time was 120-260 minutes, with an average of 186.7 minutes; the intraoperative blood loss was 30-120 ml, with an average of 62.2 ml; the number of lymph node dissection was 562, with an average of 26.7; One case of spleen injury was caused by tearing of the spleen capsule, compression and hemostasis, and no spleen was removed. No serious complications occurred during the operation.

The da Vinci robot radical gastrectomy, especially for obese and advanced gastric cancer patients, the "3+ 2" model is safe and practical. It is conducive to the new surgeons who develop robotic gastric cancer, which can reduce the resistance. The assistants can use the aspirator to provide good surgical field, reduce the difficulty of surgery, reduce the operation time, and better clinical teaching.
