Morphological changes on the human liver during minimally invasive surgery: Implications for image-guided interventions and surgical navigation
To the best of our knowledge, this is the first published study in humans to analyze the morphological changes of the liver and spleen during pneumoperitoneum. The results show a significant reduction in liver volume and change in shape and position of the liver during such laparoscopy. This deformation from preoperative to intraoperative imaging poses significant challenges for image registration, which is crucial for surgical navigation. These findings highlight the need for updated intraoperative navigation using imaging and registration to ensure accurate surgical planning.
