  • A solitary fibrous tumor (SFT) is a mesenchymal fibroblastic tumor inside the pleura, for which complete surgical resection is the standard treatment. For large SFTs, preoperative identification of tumor-feeding vessels using angiography is important for achieving complete resection without unexpected operative bleeding. Extensive adhesions can make resection difficult in a limited operative window, and pulmonary resection may be required to achieve complete SFT resection. Herein, we report successful resection of a large pleural SFT in a 39-year-old man without any complications using a 2-stage approach, in which ligation of the feeding vessels through small another operative window was the first step.

  • Extracellular matrix(ECM) is composed of the ground materials(proteoglycan) and nano size diameter fibrous proteins(ex. collagens) that together form a composite-like structure. In this study, fibrous scaffold with biomimetic architecture based on collagen nanofibers interpenetrated in PLGA/chitosan microfibrous matrix. Chitosan was selected for its structure similarity to glycosaminoglycan and neutralizing capacity for PLGA acidic metabolite. Collagen nanofiber were prepared by electrospinning. (omitted)

  • 담도폐쇄증은 원인은 알 수 없으나 간외 담도의 섬유화로 내강이 막히면서 간문부에 '섬유성 담도잔유물'의 형태로 남아있는 질환이다. 'Triangular cord' (이하 TC) sign은 간문부에 남아있는 섬유성 담도잔여물을 초음파 검사에서 나타내는 소견이다. 본 종설에서는 담도폐쇄증의 수술 및 초음파 소견의 비교, TC sign의 정의, 객관적인 진단기준, 진단의 정확도 및 감별진단에 대하여 기술하고자 한다.
