Objective: To evaluate the efficacy and safety of hepatectomy combined with cryoablation and ethanol injection in patients with unresectable multiple liver metastases from colorectal cancer.
Methods: Clinical data of 23 patients with multiple liver metastases form colorectal cancer in the Affiliated Tumor Hospital of Guangzhou Medical College between January 2005 and December 2010 were analyzed retrospectively. There were 15 males and 8 females with average age of 52.2 years. All the patients underwent hepatectomy combined with ultrasound-guided cryoablation and ethanol injection intraoperatively.
Results: Among 98 lesions in 23 patients, 45 were removed intraoperatively and 53 were treated by cryoablation and ethanol injection. Operative time for liver lesions ranged from 27 to 96 minutes and intraoperative blood loss 50 to 450 ml. One patient developed pleural effusion and 1 myoglobinuria after operation. All the patients were followed up with a median follow-up time of 34 months(8 to 70 months). The 1-, 3-, and 5-year survival rates were 83.2%, 45.5% and 37.6% respectively.
Conclusion: Hepatectomy combined with cryoablation and ethanol injection is an effective and safe treatment option for patients with unresectable multiple liver metastases from colorectal cancer.

Background/objectives: Our aim was to compare the complication rates of different embolization materials (absolute ethanol and gelatin sponges) used for combined transarterial embolization (TAE) and to investigate the impact of tumor size on operative time and cryoneedle use during percutaneous cryoablation (PCA).
Methods: We treated 27 patients (9 women and 18 men; mean age, 74 years) with 28 early-stage (T1a) renal cell carcinoma (RCC) lesions using combined TAE and PCA between September 2018 and January 2021. During TAE, 15 lesions in 14 patients were embolized using mixed absolute ethanol and iodized oil.

Article Synopsis
- Historically, musculoskeletal (MSK) tumors have been treated separately, but the complications from metastases, like pain and fractures, require a team of experts to decide on the best treatments, including surgery, radiation, or chemotherapy.
- * Recently, minimally invasive interventional therapies, particularly image-guided ablation techniques, have gained traction as promising options to effectively treat MSK tumors, offering less invasive alternatives.
- * Imaging methods like CT, which is preferred for its accessibility, guide these interventions, which include techniques like radiofrequency ablation and cryoablation, sometimes combined with other treatments for better tumor control.

Background Advances in imaging technology and the increased use of abdominal imaging have led to a rise in renal cell carcinoma (RCC) detection. While surgery remains the primary treatment for small RCCs, minimally invasive procedures like cryoablation are gaining popularity, particularly for patients with comorbidities or renal dysfunction. CT-guided cryoablation offers advantages, including high spatial resolution and real-time visualization during the procedure.

Background: The cryoablation efficacy of semisolid freezing nitrogen ethanol composite (FNEC) has been demonstrated. We aimed to investigate the feasibility of adjuvant FNEC-assisted cryoablation in different bone cavity types by assessing the perioperative complication rates.
Methods: The medical charts of patients who received intraoperative adjuvant cryoablation using semisolid FNEC for bone tumors from December 2013 to January 2018 were reviewed.
