Subcutaneous Implantation Metastasis of a Cholangiocarcinoma of the Bile Duct after Percutaneous Transhepatic Biliary Drainage (PTBD) / 대한소화기내시경학회지

Percutaneous transhepatic biliary catheterization (PTC) has not only been increasingly used in the localization of benign and malignant lesions, but it is also considered rapid, safe and effective method to establish internal and external drainage for decompression of biliary obstructions. Infections and granulomas at the catheter entry site can occasionally develop, but are easily managed. However, such technique, when used both for obtaining malignant cells for diagnosis and for percutaneous decompression of the biliary tract can exposure the patient at risk for dissemination of the tumor along the catheter tract. This rare complication has been observed in a patient who underwent percutaneous transhepatic biliary drainage (PTBD) for malignant biliary tract obstruction. Although tumor cell seeding along the catheter tract is a very rare complication, we think that PTBD should be avoided when curative resection is planned.

A Case of Intussusception Induced by Intestinal Tuberculosis / 대한소화기내시경학회지

Although intussusception is primarily a disease of children, about 5 to 10 percent of cases occur in adults. The underlying causes of adult intussusception are tumor, postoperative complication, local bowel ischemia, abnormal motility and rarely intestinal tuberculosis. Recently, we experienced a 62-year-old man with intussusception underlying pulmonary tuberculosis. The postoperative pathologic finding was intestinal tuberculosis. For its rarity, we report this case with review of literatures.
