Children with liver tumors often need surgery to remove the tumor safely. Before surgery, doctors use imaging scans like CT or MRI to see how big the liver and tumor are. But these scans may not show the full picture because the liver is tightly packed inside the rib cage and may look smaller or more compressed than it actually is. During surgery, when the liver is freed and moved out of its tight space, it can expand, making the tumor easier to remove than originally thought. This study aims to find out how much the liver’s size and volume actually change from the scans to real-time during surgery.

The goal of this study is to measure and compare liver size before and during surgery in children with liver tumors. It also aims to see if these changes affect the surgical plan like how much of the liver needs to be removed and whether these differences help achieve better outcomes. The study will also use ultrasound during surgery to see the tumor’s location and relationship with nearby blood vessels more accurately.

By understanding these changes, the research hopes to help surgeons plan safer and more effective operations. This can reduce the removal of healthy liver tissue, lower the risk of complications, and improve recovery in young patients.
