摘要
腹腔镜肿瘤切除术后套管孔转移(PSM)的确切发生率目前仍不清楚,估计为1%~2%,与开腹手术伤口转移发生率一致。其可能的发生机制有多种,包括直接伤口种植、外科操作技巧、CO2气腹的作用及机体的免疫反应等。目前PSM可能的发生机制及预防措施等方面的研究日益增多。现就这些相关因素作一综述。
The incidence of port-site metastases after laparoscopic resection of trmors, which has not clarified yet,is initially thought to be 1% -2%. It is close to the incidence of wound metastases after open surgery. Muhiple etiologic factors are associated with this complication, including direct wound contamination, surgical techniques, effects of carbon dioxide pneumoperitoneum, and changes of host immune response, etc. At present, the studies on possible etiologic mechanisms and preventional measures of PSM are increasing. The related factors mentioned above are reviewed.
