Impact of Peritoneal Gas Drain on Postoperative Pain for Gynaecological Cancer Patients With Minimally Invasive Surgery

The primary objective is to assess the efficacy of active gas aspiration compared to simple manual gas evacuation to reduce the incidence of specific laparoscopic surgery pain.

Secondary objectives of this study include :

• Comparing the evolution of specific pains after laparoscopic surgery, between study groups
• Description of postoperative antalgics consumption in each group
• Evaluating the safety of the evaluated procedure
• Evaluating the impact of the evaluated procedure on hospitalisation duration ( for patients with ambulatory surgery initially planned)
