Laparoscopic colorectal surgery with warm and humidified CO2

Randomized Trial Comparing Low Pressure in Laparoscopic Colorectal Resection With Warm and Humidified Carbon Dioxide Pneumoperitoneum Versus Low Pressure Pneumoperitoneum Alone

Not applicable Interventional Bordeaux Colorectal Institute Academy · NCT05934981

This study is testing if using warm and humidified carbon dioxide during laparoscopic colorectal surgery can help patients recover with less pain and fewer pain medications compared to the usual cold and dry method.

What this trial studies

This clinical trial aims to enhance post-operative recovery for patients undergoing laparoscopic colorectal surgery by utilizing a medical device that combines low-pressure pneumoperitoneum with heated and humidified carbon dioxide insufflation. The study is designed as a double-blind, prospective, randomized, controlled trial to compare the effects of this innovative approach against traditional cold and dry insufflation. The primary focus is to assess post-operative pain levels at 24 hours without opioid use, with the goal of improving patient outcomes and reducing analgesic consumption. Previous studies have indicated that low-pressure laparoscopic techniques can lead to shorter hospital stays and decreased pain.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 and older who are scheduled for laparoscopic colorectal surgery for benign or malignant conditions without the need for a stoma.

Not a fit: Patients who may not benefit from this study include those requiring laparotomy procedures, those with a history of severe obesity or significant comorbidities, and individuals with certain gastrointestinal diseases.

Why it matters

Potential benefit: If successful, this approach could significantly reduce post-operative pain and improve recovery times for patients undergoing colorectal surgery.

How similar studies have performed: Previous studies have shown promising results with low-pressure laparoscopic techniques, indicating that this approach may build on established findings.
