Background: Reports of port site tumor recurrences after laparoscopic-assisted resection of
colon tumors have raised concerns about the safety of laparoscopic cancer surgery. Tumor …

Background The influence of surgical manipulation and carbon dioxide pneumoperitoneum
on intraperitoneal tumour growth and port-site metastasis during laparoscopic colon …

Background: A variety of mechanisms have been proposed to explain tumor growth in port
sites following laparoscopic cancer surgery. We devised two experimental models to …

Purpose The addition of 4% O 2 and 10% N 2 O to the CO 2 pneumoperitoneum (PP),
together with slight cooling and humidification (conditioning), contributes to reducing …

Background The purpose of this study was to evaluate the effects of carbon dioxide (CO 2)
pneumoperitoneum and wound closure technique on port site tumor implantation. Methods …

BACKGROUND: Numerous anecdotal reports have documented the spread of colon cancer
to trocar sites after laparoscopic-assisted colectomy. We hypothesized that the …

Background Recent work has shown that intraoperative hypothermia is a significant source
of surgical trauma, with wide-ranging physiological and immunological sequelae. The aim of …

Background: The application of laparoscopic‐assisted surgery to gastrointestinal
malignancy has lead to the recurrence of malignancy in wounds created during these …

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

Background: Our laboratory has previously shown that tumors are established more easily
and grow larger after laparotomy than after laparoscopy. To characterize these differences in …
