%X purpose: to evaluate the influence of carbon dioxide pneumoperitoneum on abdominal wall wound healing in rats. methods: eighty rats underwent laparotomy, segmental left colon resection, and anastomosis. the animals were divided into three experimental groups and one control group: ei = pneumoperitoneum for 30 minutes before laparotomy (n=20); eii = pneumoperitoneum for 30 minutes after abdominal closure (n=20); eiii = pneumoperitoneum for 30 minutes before laparotomy and 30 minutes after abdominal closure (n=20); c = control group, without pneumoperitoneum (n=20). in each group, 10 animals were killed 7 days and 10 animals 14 days postoperatively. a segment of the abdominal wall was resected and subjected to tensile strength testing. another segment of abdominal muscle was used for histopathological analysis; the specimens were fixed in formalin and stained with hematoxylin and eosin. results: there were no differences in histopathology and tensile strength values among animals in the experimental and control groups 7 or 14 days after surgery. conclusion: under the present experimental conditions, carbon dioxide pneumoperitoneum did not interfere with abdominal wall wound healing.
