前哨淋巴结(SN)活检被期望能废除许多不必要的淋巴结清扫术从而减少并发症,已在多种癌的诊治中应用。然而,在胃癌外科中尚未被应用。此研究旨在评估对胃癌患者进行SN活检的可行性和对淋巴结情况预测的准确性。 病人和方法:实施SN活检的胃癌病例分为T1期(n=44)和T2期(n=30)。部腹术后,立即在原发胃癌周围注射吲哚氰绿(ICG)染色剂,接着切除被染色的淋巴结(SN:平均每例2.6±1.7),然后实施根治性胃大部切除手术(根2式)。从切除的标本中得到未被染色的淋
Sentinel lymph node (SN) biopsies are expected to abolish many unnecessary lymph node dissections and reduce complications, and have been used in the diagnosis and treatment of multiple cancers. However, it has not been applied in gastric surgery. The aim of this study was to evaluate the feasibility of SN biopsy of gastric cancer patients and the accuracy of prediction of lymph node status. PATIENTS AND METHODS: Gastric cancer patients undergoing SN biopsy were divided into T1 (n = 44) and T2 (n = 30) days. Immediately after abdominal surgery, indocyanine green (ICG) stains were injected around the primary gastric cancer followed by excision of the stained lymph nodes (SN: 2.6 ± 1.7 cases per case on average) followed by radical gastrectomy 2). Undyed drenches were obtained from excised specimens
