Tumor Ablation in the Abdomen

Ablation of tumors in abdominal organs is an advanced interventional radiology treatment method designed for the targeted destruction of cancer cells and benign tumors without the need for open surgery. The treatment is based on the use of concentrated energy, such as extreme heat or intense cold, delivered directly to the tumor through a special needle. This procedure is particularly common for treating liver tumors, such as hepatocellular carcinoma and colorectal metastases, as well as small kidney tumors in their early stages. The treatment is suitable for patients with small tumors, usually up to four centimeters, and for those who cannot undergo complex surgical procedures due to poor overall medical condition or the problematic location of the finding within the body.

The procedure is performed in dedicated imaging rooms under the precise guidance of ultrasound or CT, allowing the specialist physician to visualize the tumor and adjacent blood vessels in real time. Before the procedure, the patient undergoes a series of tests including coagulation functions and blood counts, and is required to fast for several hours. Following local anesthesia and deep sedation, the physician inserts the ablation needle through the skin directly into the core of the tumor. There are several methods for delivering energy, including radiofrequency waves that generate heat, microwave technology which allows for the rapid treatment of larger tumors, or controlled freezing known as cryoablation, which uses argon gas to create an ice ball around the tumor. The generated energy causes the destruction of tumor cells, turning them into scar tissue that is absorbed by the body over time while maximizing the preservation of healthy tissue surrounding the treated organ.

A skilled medical team monitors the patient throughout the procedure, which typically lasts between one and two hours. This focused approach allows for highly effective treatment of tumors where access via traditional surgery would have required extensive resection of part of the organ or full abdominal opening. The method enables very high precision thanks to the combination of technological equipment and modern imaging capabilities, which significantly reduces the impact on the overall function of the liver or kidney and allows for the maintenance of the patient's quality of life. After the procedure is completed, the patient is moved to a recovery room for several hours of close observation before being discharged home. This procedure is considered a milestone in modern oncological care, providing high-quality treatment with minimal disruption to daily life.
