Interim Results of Sentinel Node Biopsy during Laparoscopic Gastrectomy: Possible Role in Function‐Preserving Surgery for Early Cancer

Abstract

Radio-guided SN mapping during laparoscopic gastrectomy is an accurate diagnostic tool for detecting lymph node metastasis in patients with early-stage gastric cancer. Validation of this method requires further studies on technical issues, including indications, tracers, methods of lymph node retrieval, and diagnostic modalities of metastasis.
