3D Printed Tumor Models Enhance Surgery Precision

At Southampton University Hospital, surgeons are turning to the power of 3D printing to craft highly detailed tumor models, generated from CT and MRI scans. This initiative aims to enhance the precision of intricate cancer surgeries, focusing mainly on patients suffering from hilar cholangiocarcinoma—a complex, challenging form of bile duct cancer. This mirrors recent trends of leveraging 3D printing within the medical industry, as an increasing number of healthcare professionals are recognizing its transformative potential in improving patient wellbeing.

Hilar cholangiocarcinoma, a cancer that starts in the bile ducts connecting the liver to the gallbladder, presents a unique set of obstacles for medical professionals. Although surgeons have access to CT and MRI scanning to help determine the severity of the tumor, the lack of clear preoperative visibility can result in significant invasive measures being taken.

Indeed, due to the complicated nature of this cancer, surgeons frequently encounter unforeseen challenges during surgery for which they couldn’t adequately prepare for beforehand. This in turn makes it difficult for surgeons to determine the feasibility of a complete tumor removal until the surgery is already well underway. This can lead to irreversible decisions during the operation with long-term adverse outcomes for patients. Enter 3D printing.
