目的:探讨术中分站淋巴结活检在进展期胃癌根治术中的临床意义。方法:选取本院2010年2月至2012年8月收治的进展期胃癌患者97例,通过亚甲蓝对97例患者行术中分站淋巴结活检,观察不同胃癌分期淋巴结活检的准确率和检出率。结果:共有38例患者出现淋巴结转移,占39.17%,其中前哨淋巴结与非前哨淋巴结均有转移患者19例,前哨淋巴结转移患者11例,非前哨淋巴结转移患者8例;T1~T2期检查率、准确率、敏感性(96.61%、98.25%、94.44%)均高于T3期患者(82.41%、78.13%、65.00%),假阴性率(5.56%)低于T3期患者(35.00%),差异均有统计学意义(P<0.05)。结论:术中分站淋巴结活检技术可以准确预测T1~T2期胃癌转移状态,对T3期胃癌患者淋巴结清扫范围选取有一定指导意义。
Objective: To investigate the clinical significance of intraoperative sub-station lymph node biopsy in radical gastrectomy of advanced gastric cancer. Methods: A total of 97 patients with advanced gastric cancer admitted to our hospital from February 2010 to August 2012 were enrolled in this study. 97 patients underwent methylene blue intraoperative lymph node biopsy to observe the accuracy and accuracy of biopsy of different gastric cancer staging lymph nodes Rate out. Results: A total of 38 patients had lymph node metastasis, accounting for 39.17%. Among them, there were 19 cases of sentinel lymph node and non-sentinel lymph node metastasis, 11 cases of sentinel lymph node metastasis and 8 cases of non-sentinel lymph node metastasis. The accuracy and sensitivity were higher in patients with T3 (82.41%, 78.13%, 65.00%) than those in patients with T3, the false negative rate (5.56%) was lower than that in T3 patients (35.00%), All were statistically significant (P <0.05). Conclusion: Intraoperative sub-station lymph node biopsy technique can accurately predict the metastasis status of T1 ~ T2 gastric cancer and provide some guidance for the selection of lymph node dissection scope in patients with T3 gastric cancer.
