BN SO50 - The Resurgence of Veress Needle Insufflation: An Evaluation of Efficacy and Safety of One Surgeon’s Practice

Abstract Background Veress needle insufflation has been established as a safe and effective method of establishing pneumoperitoneum for laparoscopic surgery, with comparable risk profile to open methods. However, the blind nature of the procedure with potential complications such as iatrogenic bowel and blood vessel injury has seen this technique fall out of fashion with general surgeons. This study reviews the safety and efficacy of a single surgeon’s practice using Veress needle insufflation for Laparoscopic surgical procedures. Method A retrospective analysis was conducted on minimally invasive procedures performed between January 2019 and June 2024. In our practice, a standard or bariatric Veress needle is placed in a small incision at Palmer’s point. A manometer test is performed with CO2 insufflation at a low flow rate and raising the abdominal wall. If a low pressure is established, then the flow is increased to achieve adequate pneumoperitoneum before introduction of a midline 5mm camera port. Primary outcomes of this study include rate of conversion to open techniques (either Hasson’s or open cut down) and any complications. Results Of the 702 cases reviewed, five patients (0.71%) required conversion to open insufflation techniques. Two (0.28%) had bleeding from the omentum, and one patient (0.14%) experienced inadvertent bowel insufflation which was managed conservatively with no long-term morbidity. Notably there were no port site hernias. Conclusion This study supports the continued use of the Veress needle as a safe and effective method of insufflation in laparoscopic surgery. It offers minimal incision size, easier access in high BMI patients, and an alternative when adhesions and scarring limit access. Furthermore, adopting this technique can be particularly useful for appropriate port placement in robotic surgery, making it a valuable tool for modern surgical practices.
