Comparative analysis of vascular bulldog clamps used in laparoscopic liver resection

Abstract

To compare the clinical effect of Bulldog clamps with traditional Pringle for vascular occlusion during laparoscopic hepatectomy.One hundred ten patients were retrospectively investigated in this research from December 2014 to January 2019 in the second hospital of Anhui Medical University, who underwent laparoscopic liver resection using Bulldog (modified group, n = 54) and cotton tourniquet (traditional group, n = 56) for blocking the liver inflow-blood. Intraoperative blood loss, duration of the operation time, clamping time, postoperative outcomes were analyzed.All the operations were accomplished successfully without conversion to laparotomy, perioperative period clinical date was calculated. Intraoperative operative time, blood loss and resection sections had no statistical significance, but the clamping time (36.2 ± 5.6 vs 277.3 ± 88.4 s, P
