绒毛型涤纶人造血管用作动脉替代物时,纤维组织可以通过其间隙增生,作为一种支架,使上皮在其内表面再生。本文报告用它作狗总胆管成形术的实验结果。材料和方法:20条体重9～15公斤狗,分三组:第1组10条狗在总胆管前壁剪一个8～10×2～3 mm的缺口,通过缺口插入一个直径1×1.5mm近侧端有多个侧孔的聚乙烯管,远端下达十二指肠第二段,在十二指肠前壁戳孔经腹壁抽出,侧孔段
When villi-type polyester artificial blood vessels are used as arterial substitutes, fibrous tissue can proliferate through its interstices as a scaffold to regenerate the epithelium on its inner surface. This article reports its use as an experimental result of dog choledocholipinoplasty. MATERIALS AND METHODS: Twenty dogs weighing 9 to 15 kg were divided into three groups: Group 1: 10 dogs were cut an 8-10 × 2-3 mm gap in the anterior wall of the common bile duct, and a 1 × 1.5 mm The proximal end of the polyethylene tube having a plurality of side holes, the distal duodenal second segment, punctured in the anterior wall of the duodenum through the abdominal wall, the side hole segment
