Safer laparoscopic trocar entry: it's all about pressure

Area of Science:

• Surgical Innovation
• Minimally Invasive Surgery
• Laparoscopic Techniques

Background:

• Laparoscopic surgery requires adequate pneumoperitoneum for visualization and instrument manipulation.
• Current insufflation pressures are typically lower, with limited data on higher pressures.
• Assessing safety and feasibility of increased insufflation is crucial for surgical advancement.

Purpose of the Study:

• To evaluate the feasibility and safety of increasing peritoneal insufflation pressure to 25 mmHg for primary trocar insertion during laparoscopy.
• To monitor for any adverse physiological changes associated with higher insufflation pressures.
• To assess the impact on surgical entry complications and anesthetic effects.

Main Methods:

• Prospective observational study design.
• Inclusion of 1150 consecutive diagnostic or operative laparoscopies.
• Utilized Veress needle insufflation to achieve 25 mmHg before primary trocar insertion.
• Continuous monitoring for physiological changes and adverse events.

Main Results:

• Successful insufflation to 25 mmHg was achieved in all cases.
• No surgical entry complications were reported.
• No adverse clinical effects were observed during anesthesia.
• Feasibility of the procedure was confirmed.

Conclusions:

• Increasing peritoneal insufflation pressure to 25 mmHg is a feasible and safe practice for primary trocar insertion in laparoscopy.
• This technique did not lead to complications or adverse anesthetic events in the study cohort.
• Further research may explore the benefits of higher insufflation pressures in specific laparoscopic procedures.
