Image-guided percutaneous cholecystostomy: challenging the norms.

Image-guided percutaneous cholecystostomy (IGPC) is a widely recognized and regularly employed procedure in numerous institutions, serving as an indispensable cornerstone in the management of patients with acute cholecystitis. The most up-to-date literature has found that the transperitoneal route is at least as safe as the transhepatic route and that both the trocar and Seldinger techniques are equally safe and effective. The above novel insights may offer reassurance and alleviate concerns among operators performing IGPC by dispelling the fixation on previously established beliefs and thus providing flexibility, which lightens the load on the operator.
