The open approach using a small incision with direct visualization to place a device into the peritoneal cavity is known as what technique?

• A. Hasson technique
• B. Veress needle technique
• C. Palmer's technique
• D. Three-port entry

Answer: (A)

Open entry in laparoscopy uses a small incision with direct visualization to access the peritoneal cavity and place a trocar/cannula, establishing pneumoperitoneum. This is the Hasson technique. It differs from the blind Veress needle method, where insufflation begins with a needle inserted percutaneously before any trocar is placed. Palmer's point is another open-entry variant at the left upper quadrant, used in specific situations, but the classic description of entering with direct vision through a small incision points to Hasson. Three-port entry refers to port placement after access, not the initial open entry technique.
