Background: Minimally invasive techniques are increasingly applied to children with
malignant tumors. We showed previously that CO 2 used for pneumoperitoneum modulates …

Background The response of mesothelial cells to surgical trauma and bacterial
contamination is poorly defined. We have recently shown that CO 2 pneumoperitoneum …

Background. Port-site recurrences have often been reported after laparoscopic surgery for
malignant disease, and the pathogenesis is unknown. Whether different gases used to …

Purpose: It has been reported that CO 2 gas, used to establish a pneumoperitoneum during
laparoscopy, affects the behavior of tumor cells. The proto-oncogenes c-myc and HMGB-1 …

Background Experimental and clinical studies, have suggested that the CO 2
pneumoperitoneum influences the development of intraabdominal tumor dissemination and …

Background CO 2 pneumoperitoneum provides a new surgical environment to treat
malignant disease. The purpose of this study was to investigate the influence of CO 2 …

Objective: The aim of the study was to examine the effect of helium (group 2), carbon dioxide
(group 3), and heated carbon dioxide (group 4) pneumoperitoneum on survival in case of …

Background: The validity of using carbon dioxide (CO 2) pneumoperitoneum in laparoscopic
tumor surgery has not been investigated thoroughly. The oncologic effects of a gasless …

Background: The pathogenesis of port site recurrences after laparoscopic surgery for
malignant disease is still unknown. Whether different gases used to establish …

Background: The recent results of several experimental studies have suggested that tumour
implantation after laparoscopic surgery for intra‐abdominal malignancy may be partly …
