Introduction: The use of videolaparoscopy in the treatment of digestive diseases, associated with generalized peritonitis, is controverted. Objective: To develop a model of bacterial peritonitis for the evaluation of the treatments through laparotomy and through videolaparoscopy. Methods: Male Wistar rats were submitted to occlusion of the ceacum (CLP) on a rigid mold of 3mm diameter, followed by 14 punctures of the ceacum with a 15 x 10 needle. Six hours after the induction of peritonitis, the animals were treated by laparotomy or videolaparoscopy, while analysing blood cultures and the mortality rates. The treatment involved typhlectomy followed or no by peritoneal lavage with saline solution. Results: The mortality rate in one week, after CLP without treatment, was 90%. The blood cultures were positive in 80 to 100% of the animals after 3 hours, and in 60 to 80% after 24 hours, in the animals when treated with laparotomy without peritoneal lavage and in the animals treated through videolaparoscopy with or without peritoneal lavage. The mortality rate after laparotomy was 20%, whereas after videolaparoscopy it was 80%. Conclusion: The experimental model induced severe peritonitis, and the bactereamia associated with videolaparoscopy has a high mortality rate.
