Abstract

Despite emerging technologies, parenchymal transection still remains challenging in liver resection. The aim of this study is to assess the safety and efficacy of a new articulating vessel sealer for laparoscopic hepatectomy. Our hypothesis was that this new device would facilitate parenchymal transection and reduce intraoperative costs in laparoscopic hepatectomy. Within 18 months, a 5 cm bipolar articulating vessel sealer was used in 32 laparoscopic liver resections (LLR). By excluding 4 patients who underwent concomitant colorectal resections, the outcomes of the remaining 28 patients (group 1) were compared with 28 patients who underwent LLR by the same surgical group using other energy devices (group 2). Tumor type was malignant in 71% of patients (n=20) in group 1 and 89% of the patients (n=25) in group 2 (P=0.360). The number and size of tumors were similar in both groups, as well as the type of resections performed. In group 1, there was a less number of adjunctive devices (ie, energy, clip appliers, staplers) used (median 2) compared with group 2 (median 3, P=0.032). Parenchymal transection time (mean±SEM 28.2±3.5 vs. 55.2±4.1 min, respectively, P<0.001) and total operative time (200.1±13.7 vs. 242.7±14.4 min, respecti...Continue Reading
