Esohophageal stents are often used in treating malignant stricture. But, when stents are placed across the esophagogastric junction, they may lead to esophagogastric reflux. We report a case of successfully treated esophagogastric strictures using the new stent with anti-reflux mechanism (long cover type Niti-S™ esophageal stent). A 78-year-old man(More)

Following additional examinations, we diagnosed the patient with hepatocellular carcinoma and ascites with liver cirrhosis. Due to renal dysfunction, he could not undergo treatment with transcatheter arterial chemoembolization(TACE)or(More)

We treated an 80-year-old woman with gallbladder cancer. Because of her advanced age, chemotherapy was performed, but obstructive jaundice and duodenal stenosis were caused by invasion of the tumor. We inserted a metallic stent into the common bile duct and duodenum 3 times. As a result, she could eat and live at home with good quality of life.
We treated a 73-year-old woman with adenocarcinoma of the duodenum. She complained of poor appetite and weight loss. Upon close inspection, we diagnosed duodenal cancer with obstructive jaundice. Curative resection could not be performed because of swelling of the para-aortic lymph nodes. Chemotherapy using mFOLFOX6 was performed, and she survived.
