BACKGROUND: Although significant advances have been made in laparoscopic liver resection (LLR), most techniques still rely on multiple energy devices and staplers, which increase operative costs. The aim of this study was to report the initial results of a new multifunctional energy device for hepatic parenchymal transection. METHODS: Fourteen patients who underwent LLR using this new device were compared to 20 patients who had LLR using current laparoscopic techniques (CL). Data were collected prospectively. RESULTS: The groups were similar demographics and tumor type and size. Although the type of resection was similar between the groups, the parenchymal transection time was less in the Caiman group (32 ± 5 vs. 63 ± 4 min, respectively, p = 0.0001). The operative time was similar (194 ± 21 vs. 233 ± 16 min, respectively, p = 0.158). There was reduction of the number of advanced instrumentation used in the Caiman group, including the staplers. Estimated blood loss, size of surgical margin, and hospital stay were similar. There was no mortality, and morbidity was 7 % in the Caiman and 20 % in the CL group. CONCLUSIONS: This initial study shows that the new device is safe and efficient for LLR. Its main advantage is shortening of hepatic parenchymal transection time. This has implications for increasing efficiency and cost saving in LLR.
