Compare Veress needle entry and open (Hasson) entry for establishing pneumoperitoneum.

Compare Veress needle entry and open (Hasson) entry for establishing pneumoperitoneum.

• A. Hasson uses a blunt trocar with an open entry.
• B. Veress uses a blunt trocar with an open entry.
• C. Veress uses a needle to insufflate after insertion; Hasson uses a blunt trocar with an open entry; choice depends on patient factors and surgeon safety.
• D. Veress is always safer than Hasson.

Answer: (C)

The key idea is how pneumoperitoneum is created with two different entry techniques. The Veress approach uses a fine needle that is inserted through the abdominal wall into the peritoneal cavity, and CO2 is insufflated through that needle to establish pneumoperitoneum before any larger access is made. In contrast, the open (Hasson) technique involves making a small skin and fascia incision, opening the peritoneum under direct vision, and placing a blunt cannula or trocar into the abdomen to admit CO2. The choice between these methods depends on patient factors and surgeon safety: in patients with prior abdominal surgeries or suspected adhesions, the open approach can reduce the risk of blind injury and is often favored; in stable patients without high risk of adhesions, the Veress method can be quicker and less invasive. Neither method is universally safer; effectiveness and safety hinge on anatomy, prior history, and the surgeon’s experience.
