胰腺癌恶性程度高,预后不良,淋巴结转移是影响其预后的重要因素,报道胰头癌的淋巴结转移率可达73%[1]。理论上,手术切除有肿瘤转移的淋巴结是最直接有效的方法,但由于胰腺癌淋巴结转移发生早,且发生率高,使得手术根治时难以确定清扫范围和程度。一味扩大手术清扫范围势必增加手术创伤,并不能提高疗效。如何在术中示踪淋巴结转移范围,对开展精确、有效、合理的淋巴结清扫意义重大,是目前胰腺外科手术领域研究的难点和热点。本文就目前 Malignant pancreatic cancer, poor prognosis, lymph node metastasis is an important factor affecting its prognosis, reported pancreatic cancer of the lymph node metastasis rate of up to 73% [1]. In theory, surgical removal of lymph node metastases is the most direct and effective method, but because of pancreatic cancer, lymph node metastasis occurred early, and the high incidence of making it difficult to determine the scope of surgery and degree of radical surgery. Simply expand the scope of surgical cleaning is bound to increase the surgical trauma, and can not improve the curative effect. How to tracing the range of lymph node metastasis during operation is of great significance for carrying out accurate, effective and reasonable lymphadenectomy, which is a difficult and hot issue in the field of pancreatic surgery.
