Low Impact Laparoscopy for Colorectal Surgery

Low Impact Laparoscopic in Colorectal Resection: a Randomized Trial Comparing Low Pneumoperitoneum Pressure Plus Microsurgery Versus Low Pneumoperitoneum Alone

Not applicable Interventional University Hospital, Bordeaux · NCT04742881

This study is testing if using special low-pressure tools during colorectal surgery can help patients feel less pain and recover faster compared to standard tools.

What this trial studies

This clinical trial aims to enhance post-operative recovery in colorectal surgery by comparing the effects of low-pressure pneumoperitoneum combined with microlaparoscopic instruments against traditional low-pressure laparoscopy using standard instruments. It is a phase III double-blind, prospective, randomized, controlled, multi-centric trial designed to assess post-operative pain levels at 24 hours post-surgery without opioid use. The study builds on previous findings that suggest low-pressure techniques can reduce pain and length of hospital stay. Participants will undergo various colorectal procedures, and their pain levels will be measured using a visual analog scale.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older scheduled for colectomy due to malignant or benign pathology.

Not a fit: Patients requiring laparotomy procedures or those with specific conditions such as Crohn's disease or electronic implants may not benefit from this study.

Why it matters

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

How similar studies have performed: Previous studies have shown promising results with low-pressure laparoscopic techniques, indicating potential for success in this novel approach.
