Laparoscopic Colorectal Surgery Using Low-pressure Combined With Warm and Humidified Carbon Dioxide Insufflation

This study is testing whether using warm, humidified carbon dioxide gas at low pressure during laparoscopic (keyhole) colorectal surgery reduces pain, preserves body temperature, and speeds recovery compared to standard cold, dry gas at higher pressure. **You may be eligible if...** - You are 18 or older - You are scheduled for laparoscopic or robot-assisted colorectal surgery for a cancerous or benign condition - Your surgery does not require a stoma (colostomy bag) - You can consent to participate and are affiliated with a social security system **You may NOT be eligible if...** - Your surgery requires an open (non-laparoscopic) approach - You need a total or subtotal colectomy or transverse colectomy - You need a proctectomy with stoma or total coloproctectomy - You already have or are likely to need a stoma - Your procedure involves additional complex surgeries beyond the colorectal operation Talk to your doctor to see if this trial is right for you.
