Percutaneous drainage of subphrenic biliary collections using a Ring-McLean sump catheter

This communication reports three consecutive cases of subphrenic biliary collections, resulting from biliary procedures. All were successfully treated percutaneously using a 16 French Ring-McLean sump drainage catheter without the need for secondary surgical intervention. Although percutaneous drainage of fluid collections is now commonplace, this is the first reported use of this drainage catheter for subphrenic biliary collections.
