Background: Liver metastasis is present in a wide range of malignancies, with colorectal cancer as the most common site. Several minimally invasive treatments have been suggested for managing hepatic metastases, and cryoablation is among them, yet not widely used. In this systematic review, we aimed to assess the effectiveness of percutaneous cryoablation in all types of liver metastases.
Methods: A systematic search was performed in international databases, including PubMed, Scopus, Embase, and Web of Science, to find relevant studies reporting outcomes for percutaneous cryoablation in liver metastasis patients. In addition to baseline features such as mean age, gender, metastasis origin, and procedure details, procedure outcomes, including overall survival, local recurrence, quality of life (QoL), and complications, were extracted from the studies. Random-effect meta-analysis was performed to calculate the mean difference (MD) and 95% confidence interval for comparison of QoL.
Results: We screened 2131 articles. Fifteen studies on 692 patients were included. Mean overall survival ranged from 14.5-29 months. The rate of local recurrence in the included studies ranged from 9.4% to 78%, and local control progression-free survival ranged from 1 to 31 months. The total QoL decreased one week after the cryoablation procedure (-3.08 [95% Confidence interval: -4.65, -1.50], p-value <0.01) but increased one month (5.69 [3.99, 7.39], p-value <0.01) and three months (3.75 [2.25, 5.24], p-value <0.01) after the procedure.
Conclusion: Cryoablation is an effective procedure for the treatment of liver metastases, especially in cases that are poor candidates for liver resection. It could significantly improve QoL with favorable local recurrence.

Objectives: To evaluate the at-risk organs that require protection during percutaneous cryoablation (PCA) of renal tumours and the correlation with patient and target lesion characteristics, type of protective measure used and postoperative outcomes.
Materials And Methods: Single-centre retrospective review of patients with renal tumours who underwent PCA between 2008 and 2020. Final analysis included 374 tumours.

Objective: To assess tumour factors that reduce primary technical efficacy (PTE) from CT-guided renal cryoablation.
Methods: Patients were taken from the EuRECA registry between December 2014 and November 2020. To focus on tumour factors rather than individual technique, this study was limited to cases using CT and excluded procedures using cone beam, US, MRI, or laparoscopy.

Purpose: Abdominal wall endometriosis consists of endometrial tissue between the peritoneum and the abdominal wall. The established treatment involves amenorrheic drugs-not always successful and tolerated-or invasive surgery. In this scenario, minimally invasive techniques such as cryoablation are a potential option.

Over the last two decades the development of small probes has enabled percutaneous use of cryotherapy. Cryotherapy, also known as cryoablation, enables the treatment of much larger lesions than other thermal ablation techniques, particularly when using multiple evenly spaced probes. Using rapid cooling to as low as -200 degrees Celsius (at the tip of the probe), reliable, and predictable necrosis can be induced.

Purpose: The incidence of renal cell carcinoma has been steadily increasing over the past two decades, raising the need for minimally invasive approaches. We sought to present the methodology of the percutaneous cryoablation (PCA) procedure developed based on one year of experience with 81 PCA procedures.
Material And Methods: The percutaneous cryoablation programme at Wroclaw Medical University Hospital has been successfully operating for a year.
