3D腹腔镜联合纳米炭示踪剂在远端胃癌根治术中的应用

目的 探究3D腹腔镜联合纳米炭示踪剂行远端胃癌根治术的疗效。方法 回顾性分析2014年1月至2016年3月潍坊市人民医院为82例病人行纳米炭引导下3D腹腔镜辅助远端胃癌根治术治疗的临床资料,记录围手术期情况,总结其治疗效果。结果 82例病人均顺利完成手术,手术时间(205.3±23.2) min,术中出血量(105.7±22.3) mL,术后排气时间(2.1±0.5)d,术后住院时间(8.5±1.3)d；术后腹腔出血1例,吻合口瘘2例；共检获淋巴结2 567枚,平均(31.3±4.3)枚,黑染淋巴结总数1 930枚,黑染率75.2 %,黑染淋巴结转移个数为737枚,黑染淋巴结转移率38.2 %,未黑染淋巴结转移率13.2 %,淋巴结总转移率32.0 %。结论 纳米炭示踪剂具有良好的淋巴结示踪效果,3D腹腔镜联合纳米炭示踪剂行远端胃癌根治术是安全、有效、可行的。

Application of 3D laparoscopic combined with nanocarbon tracer in distal gastric cancer

Objective To explore the efficacy of 3D laparoscopic combined with nanocarbon tracer in radical distal gastrectomy for gastric cancer.Methods Clinical data of 82 patients who accepted assisted laparoscopic radical distal gastrectomy for gastric cancer guided by nanocarbon tracer form January 2014 to March 2016 were retrospectively analyzed.The perioperative situations were recorded and the treatment outcomes were summarized.Results The operations of 82patients were successfully completed.The average operation time was(205.3±23.2)min and the average amount of bleeding during operation was (105.7±22.3)mL.The time to first postoperative flatus was (2.1±0.5)d and the average postoperative hospital stay was (8.5±1.3)d.There were 1 case of abdominal bleeding and 2 cases of anastomotic fistula.Total of 2 567 lymph nodes were detected,with an average of (31.3±4.3) lymph nodes.There were 1 930 black stained lymph nodes.Black dye rate was 75.2%.The number of black stained lymph node metastasis was 737 and the rate of that was 38.2%.The unstained lymph node metastasis rate was 13.2% and the lymph node total metastasis rate was 32.0%.Conclusion Nanocarbon tracer has good effect on lymph node tracing.3D laparoscopic combined with nanocarbon tracer in radical distal gastrectomy for gastric cancer is safe,effective and feasible.
