Secondary sentinel lymph node tracing technique: a new method for tracing lymph nodes in radical gastrectomy for advanced gastric cancer.

Objective: To explore the feasibility and clinical value of secondary sentinel lymph node (SSLN) tracing technique in radical gastrectomy for advanced gastric cancer (AGC).

Methods: From January 2009 to June 2011, 247 patients who suffered from gastric angle cancer with metastasis in No. 3 group lymph nodes were divided randomly into groups A and B.

[New method of lymph node tracing in gastrectomy for advanced gastric carcinoma].

Objective: To develop a new method of lymph node tracing in gastrectomy for advanced gastric carcinoma (AGC).

Methods: Forty-six patients with gastric angle carcinoma with metastasis in the third group lymph nodes underwent radical operation. During the operation methylene blue was injected inside or around the border of the metastatic third group lymph nodes.
