Background: Surgical resection remains the treatment of choice for primary and secondary liver cancer. Complications are mainly related to blood loss. Radiofrequency-assisted liver resection (RF-R) has been proposed for parenchymal division as an alternative to clamp crushing in order to reduce blood loss. Methods: Fifty patients (median age 62 (range 30-82) years) undergoing hepatectomy were randomized to RF-R (24 patients) or the clamp-crushing method (26). In the RF-R group the resection plane was precoagulated by multiple insertion of a planar triple-cooled radiofrequency ablation needle, and then the parenchyma was sectioned using a scalpel. Results: The two groups were well matched in terms of age, sex, liver disease and type of resection. There were no deaths. Eight in the RF-R group developed complications (abscess in six, biliary fistula in three and biliary stenosis in one) compared with none of those who had resection by the crush method (P < 0.001). Two patients with cirrhosis in each group developed decompensation. Blood transfusion was required in eight of 24 patients in the RF-R group and 13 of 26 in the clamp-crushing group (P = 0.079). Conclusion: RF-R allows parenchymal resection in a clean surgical field but is associated with a higher rate of postoperative complications than the clamp-crushing technique.

Abstract

Background: Surgical resection remains the treatment of choice for primary and secondary liver cancer. Complications are mainly related to blood loss. Radiofrequency-assisted liver resection (RF-R) has been proposed for parenchymal division as an alternative to clamp crushing in order to reduce blood loss. Methods: Fifty patients (median age 62 (range 30-82) years) undergoing hepatectomy were randomized to RF-R (24 patients) or the clamp-crushing method (26). In the RF-R group the resection plane was precoagulated by multiple insertion of a planar triple-cooled radiofrequency ablation needle, and then the parenchyma was sectioned using a scalpel. Results: The two groups were well matched in terms of age, sex, liver disease and type of resection. There were no deaths. Eight in the RF-R group developed complications (abscess in six, biliary fistula in three and biliary stenosis in one) compared with none of those who had resection by the crush method (P < 0.001). Two patients with cirrhosis in each group developed decompensation. Blood transfusion was required in eight of 24 patients in the RF-R group and 13 of 26 in the clamp-crushing group (P = 0.079). Conclusion: RF-R allows parenchymal resection in a clean surgical field but is associated with a higher rate of postoperative complications than the clamp-crushing technique.
