Abstract：Objective To implore the value of CT scanning after intraperitoneal air injection in determining the changes of liver position. Methods A total of 36 patients who underwent CT scanning after pneumoperitoneum operation in the Third Medical Center of Chinese PLA General Hospital from June 2019 to June 2022 were selected to observe the changes of liver position in different positions and measure the distance between the liver edge and abdominal wall in different positions. Results After pneumoperitoneography, the liver position of 36 patients showed clear changes. Supine position: the average distance between the leading edge of the liver and the anterior abdominal wall was (4.95±1.28) cm in the intestinal adhesion group and (4.64±1.11) cm in the non-intestinal adhesion group, with no statistical difference between the two groups (t=0.754,P=0.456). Left oblique position: the mean distance between the leading edge of the liver and the right anterior abdominal wall was (5.62±1.05) cm in the intestinal adhesion group and (5.44±0.53) cm in the non-intestinal adhesion group, with no statistical difference between the two groups (t=0.609,P=0.547). Right oblique position: the mean distance between the leading edge of the liver and the left anterior abdominal wall in the intestinal adhesion group was (5.62±1.50) cm, and the mean distance between the leading edge of the liver and the left anterior abdominal wall in the non-intestinal adhesion group was (4.95±0.80) cm, with no statistical difference between the two groups (t=1.578,P=0.124). Prone position: the mean distance between the liver posterior edge and the posterior abdominal wall in the intestinal adhesion group was (4.18±0.89) cm, and the mean distance between the liver posterior edge and the posterior abdominal wall in the non-intestinal adhesion group was (4.03±1.28) cm, with no statistical difference between the two groups (t=0.401,P=0.691). Conclusions After pneumoperitoneum, CT scanning is safe and effective. The position of the liver changes significantly, and the distance from the abdominal wall space becomes larger. In the four positions, the left oblique position and the right oblique position show larger liver movement distance.
