Photodynamic therapy (PDT) for a postoperative recurrent tumor. A 76-year-old man was referred to our hospital with jaundice. He had undergone Whipple's operation due to a hilar cholangiocarcinoma 1 year ago. (A) Magnetic resonance imaging shows a contrast enhanced hilar mass with an obstructing anastomosis site. (B) A choledochoscopy shows mucosal nodularity and neovascularization at the anastomosis site. Biopsy specimens revealed adenocarcinoma. (C) Two days after PDT, a choledochoscopy shows circumferential coagulation necrosis at the PDT-treated lesion. (D) A recannalized anastomotic site and small papillary changes with no abnormal vessels can be seen on cholangioscopy 1 year after PDT. Choledochoscopic biopsy specimens revealed chronic nonspecific inflammation.
