Which technique is used to verify intraperitoneal placement before insufflation by aspirating with syringe?

• A. Percussion of the abdomen after insufflation
• B. Saline drop test
• C. Connecting insufflation at low flow
• D. Aspiration with syringe

Answer: (D)

Verifying placement before creating pneumoperitoneum relies on confirming the needle tip is in the peritoneal cavity. Attaching a small syringe to the Veress needle and aspirating uses a quick, direct check: if you can withdraw gas or clear serous fluid into the syringe, that indicates intraperitoneal placement. If there’s little or no aspirate, or you see blood or tissue, the needle may be in the abdominal wall or a non-peritoneal space, signaling the need to reposition before insufflation. This method is performed before any CO2 is introduced, making it the appropriate technique for confirming intraperitoneal placement. Other options describe assessments done after insufflation or use different verification methods, not the syringe aspiration test.
