Summary
This case report details the successful treatment of a solitary liver metastasis from colon cancer using radiofrequency ablation with hydrodissection. This minimally invasive technique proved safe and effective for subcapsular lesions, achieving a complete response.
Area of Science:
- Oncology
- Minimally Invasive Surgery
- Interventional Radiology
Background:
- Colon cancer frequently metastasizes to the liver, necessitating effective treatment strategies.
- Solitary liver metastases can be challenging to treat, especially when located near the liver capsule.
- Radiofrequency ablation (RFA) is an established technique for liver tumor ablation.
Observation:
- A 39-year-old male with resected colon cancer developed a solitary, 3 cm liver metastasis.
- Chemotherapy stabilized the lesion, but curative treatment was pursued.
- The patient underwent percutaneous RFA with intraperitoneal dielectric fluid for hydrodissection.
Findings:
- The RFA procedure with hydrodissection was technically successful.
- The technique prevented capsular breach, a known complication in subcapsular liver lesion ablation.
- Follow-up imaging confirmed a complete response, indicating successful eradication of the metastasis.
Implications:
- Peritoneal hydrodissection during RFA is a safe and effective method for treating subcapsular liver metastases.
- This technique offers a minimally invasive, curative option for select patients with colorectal cancer recurrence.
- Further research may explore broader applications of hydrodissection in liver ablation procedures.
