纳米碳标记在全腹腔镜远端胃癌根治术delta吻合中的应用

目的 研究纳米碳标记在早期胃癌全腹腔镜远端胃癌根治术delta吻合中的应用。方法 选取早期拟行远端胃癌根治术患者40例，术前行胃镜及腹部增强CT确认。随机分为纳米碳标记组20例，对照组为常规组20例，不行标记。两组患者均拟行全腹腔镜下远端胃癌根治delta吻合术，对于术中因定位不明确不能行delta吻合的中转为腹腔镜辅助胃癌根治术。统计两组行全腹腔delta吻合例数及腹腔镜辅助的例数，并对两组中转率数据进行统计学分析。结果 纳米碳标记在全腹腔镜远端胃癌根治术delta吻合术中有很好的标记作用，标记组行全腹腔镜胃癌根治术中转率明显低于对照组（P<0.05）。结论 纳米碳标记对于早期胃癌全腹腔镜下胃癌根治术delta吻合定位有重要的临床意义。

Application of Carbon Nano Label in Delta Anastomosis of Total Laparoscopic Radical Gastrectomy for Distal Gastric Cancer

Objective To investigate the application of carbon nano label in delta anastomosis of laparoscopic radical gastrectomy for early distal gastric cancer. Methods We selected 40 patients with distal gastric cancer who underwent gastroscopy and abdominal enhanced CT before surgery. They were randomly divided into carbon-labeled group (n=20) and control group (n=20). All patients underwent delta anastomosis of total laparoscopic radical gastrectomy with was coverted to Laparoscopy-assisted radical gastrectomy the patients with unclear tumor location. The number of abdominal delta anastomosis cases and laparoscopy-assisted cases in two groups were statistically analyzed, and the conversion rates of two groups were statistically analyzed. Results Carbon nano label had good labeling effect in delta anastomosis of total laparoscopic radical gastrectomy for distal gastric cancer, and the conversion rate of laparoscopic radical gastrectomy was significantly lower in carbon-labeled group than that in the control group (P<0.05). Conclusion Carbon nano label has important clinical significance for delta anastomosis in laparoscopic radical gastrectomy for early gastric cancer.
