Robot–assisted radio frequency ablation of primary and secondary liver tumours: early experience at BIR, Chennai.

Dr Iyengaran H

Abstract :

This study aimed to evaluate the technical success, radiationdose, safety and performance level of liverradiofrequency ablation using a computed tomography (CT)–guidedrobotic navigationsystem . All the procedures were done using MAXIO (Perfint healthcare Pvt Ltd.) machine using 16 slice CT scanners, under local anesthesia or IV sedation (general anesthesia) and aseptic precautions, under the supervision of trained radiologists. After marking the point of entry and target tumor, path of the needle is confirmed on the planning software and the system calculates, coordinates angle & depth and positions the robotic arm. Radiofrequency ablation was successfully completed in 15 patients with 32 lesions and confirmed on multiphasic contrast–enhanced CT. MAXIO helps in precise placement of needle in complex angulated approaches. This method is more patient friendly and ensures maximum safety. Automated planning scores over manual planning in terms of technical difficulty, number of needle passes, time consumed, number of check scans and hence the patient’s radiation dosage. This clinical trial depicts that therobotic–assisted planning and needle placement appears to be safe,with highaccuracy and a comparable radiation dose topatients.Thus making it acceptable for the routine clinical practice.
