In liver ultrasound performed by an experienced radiologist accompanying the surgery, previously unseen additional lesions can be detected in up to 30% of patients. This is important for achieving thorough cleanliness.In addition to investigating additional lesions, ultrasound contributes significantly to confirming existing lesions, determining the boundaries of the lesion to ensure effective surgery, and reviewing the structures that need to be preserved during lesion removal.

Finally, in lesions where surgical removal is not appropriate, interventional radiologists can contribute to eliminating cancer by applying ablation (burning) techniques using radiofrequency or microwave techniques. While the lesion to be ablated is visualized with an ultrasound probe, the ablation needle is advanced into the lesion to perform the procedure. Liver ultrasound is essential for the application of the ablation technique.

Intraoperative ultrasound is mostly performed with the open method and can also be performed laparoscopically in centers with suitable infrastructure and sufficient experience. In the open surgical technique, after dissecting the liver’s surrounding structures, the liver is brought to the surface from deep using sterile towels. The interventional radiologist examines the liver tissue by placing the sterile-wrapped ultrasound probe directly on the liver. If necessary, they apply the ablation method under the same conditions.

In conclusion, it is recommended to perform liver ultrasound during surgery to increase the success of liver metastasectomy in all cases where it will be performed.
