Why is the left lateral decubitus preferred over the right lateral decubitus abdomen for an acute abdomen series?

Question

Quizplus · Accepted Answer

The left lateral decubitus position is preferred over the right lateral decubitus position for an acute abdomen series because in the left position, any intraperitoneal air will be visualized along the lower liver margin. This is because the liver is higher on the right side of the body, and gas within the peritoneal cavity will rise to the highest point. By placing the patient in the left lateral decubitus position, any gas in the peritoneal cavity will migrate to the left side, allowing the lower liver margin to be better visualized. This can aid in detecting abnormalities such as free air or fluid within the peritoneal cavity.
