Randomized trial comparing low-pressure versus standard-pressure pneumoperitoneum in laparoscopic colectomy: PAROS...

Area of Science:

• Colorectal Surgery
• Minimally Invasive Surgery
• Surgical Innovation

Background:

• Laparoscopic surgery offers benefits like reduced pain and shorter hospital stays.
• Optimizing intra-abdominal pressure is key to enhancing laparoscopic colorectal surgery outcomes.
• The PAROS trial investigates the impact of reduced insufflation pressure.

Purpose of the Study:

• To evaluate if a lower intra-abdominal pressure (7 mmHg) in laparoscopic colorectal surgery reduces post-operative pain, analgesic use, and length of hospital stay compared to standard pressure (12 mmHg).
• To assess the impact of low-pressure pneumoperitoneum on patient morbidity, surgical quality, and recovery parameters.

Main Methods:

• Phase III, double-blind, randomized controlled trial (PAROS trial) involving 138 patients undergoing laparoscopic colectomy.
• Patients are randomized to either a low-pressure (7 mmHg) or standard-pressure (12 mmHg) group.
• Primary outcome: length of hospital stay; Secondary outcomes: pain, analgesic consumption, morbidity, surgical quality, and recovery metrics.

Main Results:

• Data collection and analysis are ongoing for the PAROS trial.
• The study aims to provide statistically significant comparisons between the low-pressure and standard-pressure groups.

Conclusions:

• The PAROS trial will determine if reduced intra-abdominal pressure during laparoscopic colorectal surgery enhances patient recovery and reduces hospital stay.
• Findings are expected to inform best practices for laparoscopic colorectal surgery, potentially leading to improved patient outcomes and resource utilization.
