Intraoperative findings of a laparoscopic right hemihepatectomy and CT imaging of the duodenal bulb. A A laparoscopic right hemihepatectomy had been performed for an intrahepatic bile duct cystadenocarcinoma. Medium-large (ML) NAPCs were placed at the cystic duct, right hepatic artery, and the posterior branch of the portal vein. Large NAPCs were placed at the right hepatic duct and at the anterior and posterior branches of the portal vein. A metal clip was placed at the cystic artery. B Reconstructed CT imaging showed two ML NAPCs on the duodenal bulb and one metal clip nearby
