Anterior-approach-Leberresektionen mit dem Liver-hanging-Manöver. Technik und Indikationen
Anterior approach liver resection with the liver hanging maneuver. Technique and indications
The anterior approach liver resection has advantages compared to conventional liver resection. Mobilization during conventional liver resection may cause local pressure on the tumor which could lead to tumor cell dissemination or even to tumor rupture. Furthermore, hemodynamic parameters tend to deteriorate during mobilization due to compression or twisting of the inferior vena cava. In addition, the left liver lobe often is compressed which can lead to tissue damage of the residual parenchyma. The risk of these complications can be reduced by the anterior approach technique which is facilitated by the so-called liver hanging maneuver. Appropriate indications for this technique are large tumors of the right liver lobe, tumors with infiltration of the right hepatic vein and infiltration of the vena cava from the right side, tumors with infiltration of the diaphragm and tumors of the right lobe after previous resections of the right lobe.
