Background Port-site metastasis is a critical problem in laparoscopic cancer surgery; the pathogenesis and means of prevention are still unclear. The aim of this study was to clarify by scanning electron microscopy the initial morphologic changes in the development of portsite metastasis. Methods Fifteen nude mice were injected with human gastric cancer (MKN 45) cells. Mice were killed on days 0,...
Background Although there have been studies of the effects of pneumoperitoneum on the peritoneal cavity, we still do not know whether the morphologic changes to the peritoneum are different for pneumoperitoneum vs laparotomy. Using scanning electron microscopy, we examined the murine peritoneum after pneumoperitoneum vs laparotomy and compared the changes. Methods Forty-five mice were anesthetized...
