Brief Summary
To improve post-operative recovery, medical device was developed combining low-pressure pneumoperitoneum and heated and humidified Carbon Dioxide (95˚F \& 95% RH) during laparoscopic surgery to reduce the harmful effects of cold/dry insufflation. A double-blind, prospective, randomized, controlled, monocentric trial is designed in the aim to assess the impact of low-pressure pneumoperitoneum with warm and humidified gaz on post-operative pain at 24 hours without taking opioids. It is compared with low-pressure laparoscopy with cold and dry gaz in patients undergoing colorectal surgeries.

Outcome Measures
Primary Outcomes (1)
Number of patients with pain at 24 hours after the end of the intervention by VAS ≤ 3 without taking opioids (without step 2 and step 3 analgesics).
Pain is evaluated with the Visual Analogue Scale (VAS, from 0 (no pain) to 10 (hurts worst)
At 24 hours after the end of surgery
