The Historical Interplay Of The Hasson Technique And The Veress Needle

https://en.wikipedia.org/wiki/Veress_needle

Within the academic lineage of minimally invasive surgery, the Open Hasson Technique​ and the Veress Needle Technique​ represent two distinct yet complementary philosophies for establishing pneumoperitoneum. To understand their profound connection, we must revisit the 20th century. The Veress needle, invented by Hungarian surgeon Dr. János Veress in 1938, was originally intended for the safe drainage of pneumothoraces. However, it was the surgical community's pursuit of "closed entry" that propelled the Veress needle to the forefront of laparoscopic surgery. In contrast, the Hasson technique, introduced in the 1970s, aimed to mitigate the risks of blind vascular or visceral injury by utilizing an open dissection to place the trocar under direct vision.

The dynamic tension between these two techniques has continuously elevated safety standards in laparoscopy. Initially, the Veress needle was the undisputed mainstream. Its spring-loaded stylet mechanism, facilitating a "blunt-sharp-blunt" penetration sequence, was revolutionary. However, as surgical indications expanded-particularly to include obese patients and those with prior abdominal surgery-the limitations of blind entry became apparent. It was within this context that the Hasson technique emerged as a safer alternative for high-risk cohorts.

Yet, the Hasson technique is not without drawbacks; it requires larger incisions, longer operative times, and carries a risk of herniation. Consequently, modern minimally invasive surgery has not abandoned the Veress needle but rather refined it through the lens of the "Hasson spirit"-namely, a meticulous respect for anatomical planes and an unwavering commitment to safety. This refinement is evident in every iteration of needle design: from single distal openings to side-port configurations, from standard stainless steel to high-polish surfaces, and from reliance on tactile feedback alone to the integration of pressure monitoring. Today, the "fusion" of these techniques refers to the adoption of Hassonian rigor when employing the Veress needle-such as utilizing Palmer's Point, employing a two-step insertion technique, and performing stringent negative pressure and aspiration tests prior to insufflation.

This historical evolution teaches us that the Veress needle's enduring relevance stems not from perfection, but from generations of surgeons striving-guided by the Hasson spirit-to minimize risks through technological innovation and procedural optimization. To discuss the Veress needle today is to discuss the art of simulating direct-vision safety under blind conditions through exquisite instrument design and standardized protocols. This art encapsulates a century of minimally invasive progress and forms the bedrock for future advancements.
