Exposure of the angle of His (AOH) with liver retraction is one of the key processes during laparoscopic sleeve gastrectomy (LSG). A new internal liver retractor, the LiVac (LiVac, Pty Ltd.) has recently been introduced. This study was conducted to evaluate the feasibility of the LiVac in LSG. We applied the LiVac in 20 patients who received LSG. The feasibility was assessed by exposure of the AOH, operation time, complications, and changes of aspartate transaminase and alanine transaminase. In all 20 patients, exposure of the AOH was successful. The mean operation time was 88 minutes. The changes in preoperative and postoperative aspartate transaminase and alanine transaminase levels were 18.6 and 9.1 U/L, respectively. There were no related morbidities. In LSG, exposure of the AOH using the LiVac was technically feasible.
