PTGBDルートからのランデブー法で経乳頭的処置を完遂できた2症例

抄録

We reported the cases of 2 patients who we successfully treated using the rendezvous method from the percutaneous transhepatic gallbladder drainage (PTGBD) route. In case 1, a 69-year-old male with cholangiocarcinoma, we performed PTGBD because bile duct cannulation and percutaneous transhepatic bile drainage (PTBD) were difficult. Later, we successfully placed a metal stent using the rendezvous method via the PTGBD route. In case 2, an 81-year-old female with choledocholithiasis, we performed PTGBD because cholangiography and PTBD were difficult as a result of parapapillary diverticulum. Later, we successfully completed choledocholithotomy by the rendezvous method via the PTGBD route. These cases suggested that the rendezvous method via the PTGBD route should be considered when the transpapillary approach is difficult.
