Robot-assisted Modified Kasai Portoenterostomy Versus Open Kasai Portoenterostomy for Biliary Atresia

"1. A 1.0 cm incision was made around the umblilicus for the camera port. 1.Firstly, the Exploring hepatic subcapsular spider-like telangiectasis (HSST) sign at the surface of the liver, and indocyanine green (ICG) cholangiography were observed to confirm the BA diagnosis.~2. dissecting forceps and electric scissors were applied to dissociate the atresia bile ducts and lymph nodes in portal hepatis. Exposed the hepatic artery and portal vein. All portal vein tributaries that drain into the fibrous cone were coagulated by bipolar coagulation to expose the portal plate for resection. With electric scissors help, the fibrous plate was horizontally cut from the middle of the portal plate and transected from to the left and to the right sides which was the Glissonian systems enter the liver parenchyma until see the bile outflow by verified by ICG. The opening of microbile ducts and abundant bile outflow were clearly visible under 10× camera of Da Vinci robot."

All portal vein tributaries that drain into the fibrous cone were coagulated by bipolar coagulation to expose the portal plate for resection. With scissors help, the fibrous cone of the hilar region was transected from left to right (the level of transection depends on adequate bile outflow).
