What Is The Veress Needle Used For? — A Versatile Tool Across Gynecology, General Surgery, And Urology

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

Although the basic principle of the Veress needle is identical in all specialties, each discipline emphasizes different nuances in its application and technique. Understanding these differences provides a more complete picture of its clinical value.

Gynecology: The Veress Needle's Traditional Home

Gynecology was the first specialty to adopt the Veress needle for laparoscopy. As early as 1947, French gynecologist Raoul Palmer​ reported using it to establish pneumoperitoneum for diagnostic laparoscopy.

Today, in gynecologic surgery the Veress needle is routinely used to create the pneumoperitoneum for:

Infertility evaluation

Ovarian cystectomy

Myomectomy

Total laparoscopic hysterectomy

Gynecologic patients often have relatively thin abdominal walls and a widened pelvic inlet, contributing to high success and low complication rates. In patients with a history of lower abdominal surgery, gynecologists frequently select Palmer's point​ (left upper quadrant, lateral to the rectus) as an alternate entry site to avoid adherent bowel.

General Surgery: The Workhorse for Cholecystectomy and Appendectomy

In general surgery, the Veress needle is most commonly used to establish pneumoperitoneum for:

Laparoscopic cholecystectomy

Laparoscopic appendectomy

The standard entry site is the umbilicus. General surgery patients show wide variation in body habitus-from cachectic to morbidly obese.

In obese patients, longer needles (150–160 mm) are required, and insertion should be strictly perpendicular to the abdominal wall to avoid subcutaneous tunneling.

In inguinal hernia repair, the Veress needle may be introduced at a site remote from the hernia sac to prevent inadvertent injury to herniated contents.

Urology: Special Considerations for Retroperitoneal Access

In urology, laparoscopic procedures such as:

Renal cyst decortication

Radical or partial nephrectomy

Adrenalectomy

…may be performed via a transperitoneal or retroperitoneal approach.

When the retroperitoneal route is chosen, the Veress needle is used not to enter the peritoneal cavity but to insufflate the retroperitoneal space, typically via a puncture site below the 12th rib and above the iliac crest.

This demands precise anatomic orientation to avoid injury to the kidney, ureter, or major retroperitoneal vessels-with the spring-loaded blunt stylet providing the same protective benefit as in intraperitoneal use.

Bariatric (Weight-Loss) Surgery: Meeting the Challenge of the Thick Abdominal Wall

In bariatric procedures (sleeve gastrectomy, Roux-en-Y gastric bypass), patients often have abdominal wall thickness several times that of average individuals.

A lengthened Veress needle (≥150 mm)​ is mandatory.

Insertion technique must be especially controlled.

Some surgeons opt for an optical trocar or Hasson open technique, but the Veress needle remains the preferred first choice among many experienced bariatric surgeons due to its speed and minimal invasiveness.

In Summary

What is the Veress needle used for?​

It is the universal pneumoperitoneum-established instrument​ across multiple surgical specialties-gynecology, general surgery, urology, and bariatric surgery alike. Its role is consistent: to safely create the initial operative space-but the precise technique and entry strategy adapt flexibly to patient anatomy and surgical approach.
