Department of Obstetrics and Gynecology, La Conception University Hospital, 147 Boulevard Baille, 13005, Marseille, France.
Background: The arm of this study was to assess the role of peritoneal closure in the prevention of port site metastasis after carbon dioxide (CO2) CO2 pneumoperitoneum.
Methods: We developed a xenograft ovarian cancer model by intraperitoneal injection of 27 106 IGR-OV1 line cells in nude rats Seven days after the inoculation, the animals underwent a CO2 pneumoperitoneum. At the end of the procedure, port sites were randomly closed either with suture of peritoneum (n = 14, group A) or without suture of peritoneum (n = 12, group B).

Department of Obstetrics and Gynecology, La Conception University Hospital, Marseille, 147 Boulevard Baille, 13385 Cedex 05, France.
Background: The influence on intraperitoneal tumor growth of the choice of gas and pneumoperitoneum pressure during laparoscopy is still unknown. This study compared tumor growth after laparoscopy with different gases and pneumoperitoneum pressures in an immunodeficient model.
Methods: In an initial experiment, 60 nude rats were randomly allocated to undergo laparoscopy at different pneumoperitoneum pressures (gasless, 4 mmHg, or 8 mm Hg.
