Liver Parenchymal Transection Through Radiofrequency Ablation Using a Radial Probe: Technical Report of a New Modality

Venu Bhargava Mulpuri et al. Cureus. .

Abstract

Various techniques have been reported to reduce blood loss during a parenchymal transection, and the radiofrequency ablation (RFA) technique is one of them. Owing to the charring of the adjacent liver tissue and the inability to use the conventional RFA techniques near major vessels, this study used a radial fiber of RFA. This technical report thus describes a technique to perform parenchymal transection using a radial fiber as well as its advantages and disadvantages. A radial fiber dissipates the energy radially and it has the added advantage of placing along the same and perpendicular axis of the liver parenchyma; it has been used in three patients in this study. The total intraoperative blood loss was 30-50 ml during parenchymal transection, and the intraoperative duration was 120-170 min. Bile leak was noted in one patient, which was then managed using the conventional treatment. Through the present technique, the fiber can be used in the vicinity of major blood vessels and necrosis and charring can be prevented. Although radial fiber has some advantages, it remains in the preliminary stage and requires further validation.

Keywords: liver parenchymal transection; liver parenchymal transection using radiofrequency ablation; liver parenchymal transection with minimal blood loss; liver transection using radial probe; newer technique of liver parenchymal transection; radiofrequency ablation (rfa).
