What is the recommended positioning for diagnostic laparoscopy for suspected appendicitis?

• A. Stand on the right; Trendelenburg with right tilt
• B. Prone
• C. Tuck left arm; surgeon and assistant to left; Trendelenberg with left tilt
• D. Supine with arms extended

Answer: (C)

Maximizing exposure of the right lower quadrant while keeping the patient safe and enabling ergonomic instrument use is the key idea. Placing the patient in Trendelenburg with a left tilt uses gravity to move the abdominal viscera away from the right lower quadrant, making the cecum and appendix more accessible and visible during diagnostic laparoscopy. Having the surgeon and assistant on the left side supports proper instrument triangulation and port orientation for appendiceal assessment, and tucking the left arm protects the patient from nerve or tissue injury and frees space for instruments. Other positions would hinder exposure or ergonomics: standing on the right complicates access to the right lower quadrant; a prone position is not conducive to anterior abdominal work; and a supine position with arms extended increases the risk of arm injury and offers less optimal visualization and instrument maneuverability.
