A kit of parts for perihepatic packing includes a sac, at least one securing device, and a first inflation/deflation device. The sac has front and back walls, and a periphery. The front and back walls are joined together along the periphery to define an enclosure. The periphery has top and bottom edges, and the sac is foldable to a folded configuration in which the top and bottom edges are brought towards each other. The top edge has a notch extending inwardly towards the bottom edge. The sac has first and second side portions on first and second sides of the notch. At least a portion of the sac is translucent. The securing device facilitates securing of the sac in the folded configuration. The first inflation/deflation device adds a fluid to the enclosure to inflate the sac or removes the fluid from the enclosure to deflate the sac.
