From: Remote-controlled cholangiography injection device: first clinical study in China
Results of remote-controlled cholangiography. a Normal biliary system. The common bile duct, intrahepatic bile duct and part of the intestinal mucosa are exhibited. b Right hemihepatectomy. The common bile duct and left hepatic duct are well visualized. c Hilar cholangiocarcinoma. The left and right hepatic ducts and their branches can be fully visualized through PTCD. The common hepatic duct, common bile duct and duodenum are not visualized. d Multiple biliary calculus. Multiple filling defects of the biliary system are displayed. Dilation and filling defects of the right hepatic duct can be seen. e Magnetic compressing biliary-intestinal anastomosis. The bile duct was connected to the intestine by a pair of magnets. The biliary system and intestinal mucosa can be clearly seen. f Postorthotopic liver transplantation. The biliary system is visualized well, and the anastomosis of the common bile duct is unobstructed
