AbstractTo 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 < .001) was significantly shorter in the bulldog group. Albumin, alanine aminotransferase, aspartate aminotransferase and serum total bilirubin had no statistical differences in postoperative day (POD) 1and 3, but POD 5 alanine aminotransferase (71.0 ± 46.8vs 105.8 ± 61.7IU/L P = .018) and aspartate aminotransferase (72.8 ± 39.7 vs 100.2 ± 16.7 IU/L P = .028). The postoperative hospital stays (7.02 ± 1.56 vs 8.50 ± 2.35 days P = .026) in bulldog group were lower than cotton group and differences had statistical significance. The C-reactive protein levels were significantly higher in the traditional group than in the modified group on POD 3 (46.3 ± 19.2 vs 57.7 ± 23.9 mg/L P = .019), and POD5 (13.3 ± 4.2 vs 17.5 ± 7.3 mg/L P = .001). There were 8 postoperative complications occurred in cotton group, while there was 5 in Bulldog group, all patients with complications were discharged after adequate drainage and symptomatic treatment.Bulldog is an effectively performed approach for vascular occlusion during laparoscopic hepatectomy than traditional Pringle maneuver.Copyright © 2021 the Author(s).
