Endoscopic Application of Modified Gianturco Z Biliary Stent / 대한소화기내시경학회지

Palliative treatment of malignant biliary obstructions represent the principal indications of endoscopic or percutaneous transhepatic implantation of endoprostheses. Many kinds of biliary stents have been used to maintain patency of the bile ducts obstructed by benign or malignant strictures. However, the biliary stent in current use, has a tendency to become blocked. In order to maintain a long-term stent patency before clogging, biliary stents with large diameters are needed and some kinds of expandable metal stents are proposed. The Hanaro stent (Sooho medi-tech Co. LTD, Seoul, Korea) is a modified Gianturco Z biliary stent, made of 0,01-inch stainless steel wire with a zigzag pattern. It has a spiral, cylindrical configuration and is 10 mm in expanded diameter. It hes been used only with the percutaneous transhepatic technique. In this article, we describe a new method for endoscopic retrograde placement of a modified Gianturco Z biliary stent. This report describes our experience on endoscopic application of a modified Gianturco Z biliary stent in a patient with malignant obstruction of the distal common bile duct.

A Case of Plummer - Vinson Syndrome Treated with Endoscopic Balloon Dilatation / 대한소화기내시경학회지

Plummer-Vinson syndrome is characterized by dysphagia associated with anemia, glossitis and esophageal web. The cause of this syndrome is still not clear, but the most important one is thought to be the iron deficiency. The patient with small sized ageal web is treated by administration of iron but large sized web with dyspha gia requires breakage of web. In the following case report, we describe a patient with Plummer-Vinson syndrome who showed clinical improvement after treatmeat with endoscopic balloon dilatation of upper esophageal web with a review of literatures.

A Case of Duodenal Perforation following Endoscopic Biliary Drainage (EBD) / 대한소화기내시경학회지

Placement of an endoprosthesis for palliative decompression of biliary obstruction has been advocated as an effective alternative for interanl-external drainage catheters, of which the care and psychological impact of the external segment protruded through the skin has been a difficult problem.
