Once the pigtail is visualized to be securely lodged into the gallbladder, the guide wire is removed and a gravity drain is attached to the catheter. The Seldinger technique allows for a smaller needle size, which decreases perforation risk. [9] Trocar technique. The Trocar technique starts with loading an 8 French pigtail catheter over a trocar.
The drainage catheter is then removed over the guidewire and sheath is inserted into the ducts (7 to 8 French size). Contrast is then injected through the sheath to identify any stones or strictures. If a stricture is identified, put in biliary manipulation catheter with guidewire measuring 0.035 inches and commence balloon dilatation (with ...
Although they may not drain any liver parenchyma, they can be a source of a bile leak or biliary peritonitis after cholecystectomy in both adults and children. If an accessory bile duct goes unrecognized at the time of the gallbladder removal, 5–7 days post-operative the patient will develop bile peritonitis, [10] an easily treatable complication with a morbidity rate of 44% if left untreated.
A surgically created passage between the common bile duct and the jejunum in a procedure called a choledochojejunostomy, can be carried out to relieve the symptoms of biliary obstruction as well as allows the bile duct to drain. [5] In infants with biliary atresia, hepatoportoenterostomy is an alternative method of providing bile drainage.
Passive drains rely on gravity or capillary action to remove fluid, whereas active drains rely on a suction/vacuum force, whether that be through connection to wall suction, a portable suction device, or a bulb that has been squeezed to create a vacuum. Open drains are commonly used for superficial wounds and drain into dressings or a stoma bag.
A hepatoportoenterostomy or Kasai portoenterostomy is a surgical treatment performed on infants with Type IVb choledochal cyst and biliary atresia to allow for bile drainage. In these infants, the bile is not able to drain normally from the small bile ducts within the liver into the larger bile ducts that connect to the gall bladder and small ...

The rest of the gallbladder drains into 1-2 small cystic veins which then usually empty into either the hepatic portal vein within the liver, or [1] into tributaries of the hepatic portal venous system that drain either the proximal bile duct or hepatic ducts; [1] [2] rarely, one or more cystic vein(s) drain(s) into the right branch of the ...
