title: Refined suture techniques to prevent bleeding from accidental slippage of vascular clamps during living donor hepatectomy.
abstract: Accidental slippage of vascular clamps during living donor hepatectomy can induce brisk bleeding and even imperil the donor. After practicing more than 1000 cases of living donor hepatectomy, the investigators realized that specialized suture techniques were important to secure the vascular closure to prevent unnecessary bleeding. For secure division of intrahepatic vein branches, we devised a continuous penetration suture method in which the orders of procedures were changed to clamping-closure-cut sequence. For secure division of the main and accessory hepatic vein branches from the inferior vena cava, we applied stay sutures at each corner and midpoint of the hepatic vein stump so as not to permit its slippage. After application of these methods, we did not experience any episode of accidental clamp slippage. We are sure that these suture techniques are beneficial to prevent unnecessary bleeding during living donor hepatectomy and to make surgeons feel at ease during the living donor operation.
