肝门部胆管癌术中淋巴结清扫的研究现状

Current status of intraoperative lymph node dissection for hilar cholangiocarcinoma

摘要:

淋巴结转移是严重影响肝门部胆管癌(HCCA)患者手术预后的独立因素。淋巴结清扫是肝门胆管癌根治性切除术的重要内容,但关于术中淋巴结清扫的定义、范围及清扫数目仍存在较多争议。针对以上问题近年来国内外有较多研究,也有不少新观点。现有观点认为,术中常规对肝十二指肠韧带内、肝总动脉旁和胰头十二指肠后方的淋巴结(第12、8、13组)进行骨骼化清扫能够为HCCA患者带来明显的生存获益,但术中清扫腹腔干、腹主动脉及下腔静脉等周围淋巴结是否能为患者带来生存获益尚不明确;术中适当增加淋巴结清扫数目,不仅能够明显改善N0期患者的生存预后,还可提高阳性淋巴结的检出率,为疾病的分期获得足够的信息,但过度增加淋巴结清扫数目在实际操作中不仅难以实现,还可能导致术后并发症的发生率增加。因此,肝门部胆管癌术中淋巴结清扫相关问题尚需进一步研究。

Lymphatic metastasis is an independent prognostic factor for surgical prognosis of patients with hilar cholangiocarcinoma (HCCA) . Lymph node dissection is an important content of radical resection of HCCA, but there are still many disputes about the definition, scope and dissection numbers of intraoperative lymph node dissection. There has been a lot of research being done at home and abroad in recent years focusing on the above problems, and novel insights have also been proposed.According to the current view, routine skeletal dissection of lymph nodes in the duodenum ligament of liver, the common hepatic artery, and the posterior part of the duodenum of pancreas head (the 12 th group, the 8 th group and the 13 th group) during operation can bring significant survival benefits to patients with HCCA. However, it is still not clear whether the dissection of peripheral lymph node in truncus coeliacus, aorta abdominalis, and venae cava inferior during operation can bring survival benefits to HCCA patients during operation. Properly increasing the number of lymph node dissection during operation can not only significantly improve the survival prognosis of the patients of HCCA with stage N0, but also improve the detection rate of positive lymph nodes and obtain enough information for the stage of the disease. However, the excessive increase of total lymph node count is not only difficult to achieve in practice, but may also lead to an increase in the incidence of postoperative complications. Therefore, further investigation is needed in intraoperative lymph node dissection of HCCA.
