Photodynamic therapy for hepatic hilar intraductal papillary neoplasm of the bile duct: a case report
Intraductal papillary neoplasm of the bile duct (IPNB) is a rare disease that is characterized by papillary or villous neoplasm within the lumen of the bile duct.1 IPNB can develop anywhere along the biliary tree.2 In principle, aggressive resection is recommended as the first choice. However, hepatectomy is too aggressive for small localized tumors without significant invasion. Here, we report a case of a small hilar IPNB that was diagnosed using a digital cholangioscope (SpyGlass, Boston Scientific, Marlborough, Mass) and treated by cholangioscopy-guided photodynamic therapy (PDT) (Guoyi Huake, Suzhou, China).Oxygen saturation imaging as a useful tool for visualizing the mode of action of photodynamic therapy for esophageal cancer
Oxygen saturation (OS) imaging is a novel technique that directly measures and visualizes the tissue oxygen saturation at the surface of the GI tract. Our purpose was to evaluate the ability of OS imaging to visualize the action mode of photodynamic therapy (PDT).
