作者采用Ｂ超引导下经皮胃壁穿刺注墨的方法，对２７例胃癌病人术前穿刺注墨，术中观察淋巴结墨染情况，作淋巴结清除术。并与同期３１例未穿刺注墨组作对照。结果显示：注墨组平均每例清除淋巴结３６个，转移率６７％，转移度１３％。对照组平均每例清除淋巴结２３个，转移率７１％，转移度１９％。其中ｎ３、ｎ４站淋巴结清除率，注墨组５９％，对照组２３％（Ｐ＜０．０１）。同内镜下胃壁穿刺注墨比较，Ｂ超引导下胃壁穿刺注墨具有指示准确、穿刺成功率高（８９％）、病人易接受等优点。
The authors used the method of B-ultrasound-guided percutaneous gastric wall puncture and ink injection to puncture and inject ink before surgery in 27 cases of gastric cancer patients. During operation, lymph node ink staining was performed and lymph node dissection was performed. And compared with the same period of 31 cases without puncture ink group as a control. The results showed that the average number of lymph nodes in each group was 36, and the metastasis rate was 67%. The degree of metastasis was 13%. In the control group, 23 cases of lymph nodes were removed, with a metastasis rate of 71% and a degree of metastasis of 19%. Among them, n3 and n4 lymph node clearance rates were 59% in the ink injection group and 23% in the control group (P<0.01). Compared with endoscopic puncture and injecting ink under the endoscope, B-ultrasound guided puncture and injection of ink on the stomach wall has the advantages of accurate indication, high puncture success rate (89%), and easy patient acceptance.
