  schema:description "Two ways of removing the piece of liver the gallbladder sits on during a gallbladder cancer operation: a wedge of about two centimetres around the gallbladder bed, or the whole of the two anatomical liver segments (IVb and V) that touch it. The larger operation clears more tissue but carries more complications, and the evidence does not clearly favour either."@en ;
