One of the most relevant technologic advancements in laparoscopic liver resection (LLR) is owing to the improved ability to safely secure and divide vascular and biliary structures and the liver parenchyma by the use of endostaplers. We compared, retrospectively, 35 LLRs with the Tri-Staple technology versus 57 LLRs without, during a 14-month period. Colorectal liver metastases were overall the main indication for LLR. Neither major hepatectomy nor left lateral sectionectomy was done in the nonstapled group. Mean surgical time and blood loss were similar, whereas the tumor number and size were significantly larger in the stapled group (P ≤ 0.01). The conversion rate was 0% and 3.5% (n = 2); and the morbidity rate was 9% (n = 3) and 12% (n = 7), respectively, in the stapled and nonstapled group (P = 0.8). No overall 3-month mortality was recorded. Endo GIA Reloads with Tri-Staple technology allow a proper division of the intrahepatic vessels and biliary structure. These devices in LLRs are safe and feasible, allowing major hepatectomy and complex cases as 2-staged procedures and laparoscopic living donor liver resections.
