Therapeutic endoscopic retrograde cholan-giopancreatography using balloon enteroscopy has been shown to be feasible and effective in patients with such strictures. However, when a benign anas-tomotic stricture is severe, a dilation catheter cannot pass through the stricture despite successful insertion of the guidewire. We report on the usefulness of the Soehendra Stent Retriever over a guidewire for dilating a severe bilioenteric or pancreatoenteric anastomotic stricture under short double-balloon enteroscopy, in two patients with surgically altered anatomies.展开更多
An 85-year-old man with HCV infection and diabetes mellitus was diagnosed as having hepatocellular carcinoma （HCC, 13 cm in diameter） based on high serum alpha-fetoprotein （AFP）, AFP-L3, and des-y-carboxy prothrom...An 85-year-old man with HCV infection and diabetes mellitus was diagnosed as having hepatocellular carcinoma （HCC, 13 cm in diameter） based on high serum alpha-fetoprotein （AFP）, AFP-L3, and des-y-carboxy prothrombin levels as well as typical enhancement pattern on contrast-enhanced CT. The patient did not receive any interventional treatments because of advanced age and the advanced stage of HCC. He chose to take vitamin K, which was reported to suppress the growth of HCC in vitro. Three months after starting vitamin K, all three tumor markers were normalized and HCC was markedly regressed, showing no enhancement in the early arterial phase on CT. Here we present the report describing the regression of HCC during the administration of vitamin K.展开更多

She underwent left upper lobectomy with mediastinal lymph node dissection and concomitant resection of the left phrenic nerve, vagus nerve and pericardium. She received adjuvant chemotherapy, but had tumor recurrence. We then performed left completion pneumonectomy, but could not remove the tumor completely because of rapid tumor invasion to the left atrium. Urgent surgery should be considered for recurrent resectable PPC.展开更多
