CURATIVE TREATMENT OF COLORECTAL CANCER SOLITARY METASTASIS TO LIVER SUBCAPSULE BY PERCUTANEOUS US GUIDED RADIOFREQUENCY ABLATION USING HYDRODISSECTION (CASE REPORT).

Case report presents the successful treatment of solitary liver metastasis in a patient with resected colon cancer. A 39-year-old male underwent left hemicolectomy with colostomy formation followed by chemotherapy for a moderately differentiated adenocarcinoma of the colon. Two years later, a liver metastatic lesion was detected. Patient received chemotherapy; the mass remained stable in size, measuring up to 3 cm in diameter. Low-invasive percutaneous curative treatment by Radiofrequency ablation was conducted using hydrodissection by dielectric fluid intraperitoneal introduction for hydrodissection. The follow-up imaging showed the complete response to treatment. The ablation technique including peritoneal hydrodissection, described in paper avoids capsular breach and appears safe and technically effective in subcapsular lesions treatment.
