After percutaneous transhepatic gallbladder drainage, due to the presence of surgical risk factors, we opted to perform gallstone removal through percutaneous transhepatic cholangioscopy instead of cholecystectomy. ICPN, which was accidentally detected after the removal of the gallbladder stones, was also endoscopically removed. After 4\u2009years, the patient came back to the hospital with a large gallbladder mass.
