Table 2 Operative characteristics of patients subjected to liver resection with Intrahepatic (IHD) and Extrahepatic (EHD) hilar division.

From: Association between biliary complications and technique of hilar division (extrahepatic vs. intrahepatic) in major liver resections

  IHD group (n = 100) EHD group (n = 50)
1. Type of liver resection n°(%):   
a. right hepatectomy 60 (60%) 30 (60%)
b. left hepatectomy 20 (20%) 12 (24%)
c. extended right hepatectomy 12 (12%) 5 (10%)
d. extended left hepatectomy 8 (8%) 3 (6%)
2. Parenchymal transection technique (%):   
a. clamp crushing 18 (18%) 14 (28%) (p < 0.05)
b. sharp transection 82 (82%) 36 (72%)
3. Vascular control technique   
a.TVC* 6 (6%) 3 (6%)
b. Pringle maneuver 23 (23%) 10 (20%)
c. SHVE+ 71(71%) 29(58%)
d. without vascular control 0 (0%) 8 (16%) (p < 0,05)
4. Operative time (minutes, mean ± SD) 214 ± 38 245 ± 50 (p < 0.05)
5. Ischemic time (minutes, mean ± SD) 40 ± 6 38 ± 8
6. Blood loss (ml, median-range) 540 (150–2600) 680 (150–3000)
6. Ischemic preconditioning no (%) 65(59%) 25(50%)
  1. * TVC: Total Vascular Control
  2. + SHVE: Selective Hepatic Vascular Exclusion
