Study Description

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.

Detailed Description: Laparoscopy is the gold standard in colorectal surgery with many benefits in term of morbidity, post-operative pain and analgesic consumption. However, the pneumoperitoneum created for the laparoscopy has several negatives impact and limits (specific pain following abdominal distension, visibility, physiological repercussion). To improve recovery after colorectal laparoscopic surgery it was realized a first study (PAROS 1) which showed that low-pressure laparoscopic colectomy for benign or malign disease was feasible and safe with shorter length of stay (3 vs. 4 days; p=0.001), and decrease post-operative pain (VAS ≤ 3 à H8: 87% vs. 72% ; p=0.039) with reduction of analgesic consumption (step II analgesics: 73% vs. 88% ; p=0.032 and step 3 analgesics: (10% vs.23% ; p=0.042) (Br J Surg. 2021 Aug 19;108(8):998-1005) Simultaneously, the development of humidification medical device, referring to the administration of heated and humidified CO2 during laparoscopic surgery, aims to reduce the effects of cell drying and evaporative heat loss when the body is exposed to cold CO2. and dry during laparoscopic surgery. The state of the CO2 traditionally used during laparoscopic surgery and the ambient air during open surgery is very different from that of the human body, as it directly extracts heat and humidity from the already fragile patient. The introduction of heated and humidified CO2 provides an environment that reflects the physiological state of the peritoneum. Added to the benefits of low pressure, the advantages of surgical humidification seem very positive. During surgery, surgical humidification would reduce the incidence of perioperative hypothermia, improve local tissue oxygenation and local tissue perfusion. After surgery, it would improve core body temperature, reduce local peritoneal inflammation, surgical site infection rate and recovery time. The benefits of a warmed and humidified CO2 also seem very positive in terms of reducing postoperative pain and analgesic consumption. In the long term, it would reduce adhesion formation, tumor burden, metastases, and economic cost. The aim of the study is to assess the impact of low-pressure pneumoperitoneum with warm and humidified CO2 insufflation on post-operative pain without taking opioids, compared with low-pressure laparoscopy with cold and dry gas insufflation.
