What is the primary use of the Verres needle in surgical procedures?

The primary use of the Verres needle in surgical procedures is to create a pneumoperitoneum. This is a crucial step in laparoscopic surgeries, where the abdomen needs to be inflated with carbon dioxide gas to create a working space for the surgeon. By inserting the Verres needle into the abdominal cavity, gas is introduced safely and efficiently, allowing the surgeon to visualize and access internal structures through small incisions.

The creation of pneumoperitoneum is essential because it lifts the abdominal wall away from the organs, reducing the risk of injury and enhancing visibility during laparoscopic procedures. This technique is commonly used in various abdominal surgeries, such as cholecystectomy and appendectomy, where minimally invasive approaches are preferred.

Other options do not accurately reflect the primary function of the Verres needle in surgical practice. Grasping tissues is more typically done with forceps or scissors, while suturing is accomplished with needle holders and sutures. Dilation refers to expanding structures typically addressed using different instruments, such as dilators or bougies. Therefore, the focus remains on the Verres needle's important role in establishing a pneumoperitoneum as a vital step in laparoscopic surgery.
