经皮胆道引流术的有效率及并发症各家报道不一,在晚期恶性肿瘤病例,有效率达90%左右。从经皮胆道内支架放置术和球囊扩张术是相对安全的,前者报道的并发症在7%～42%,后者成功率为40%～90%,良性病变成功率更高。放置塑料支架要把肝内的通道扩张到14～16F,而金属支架只需7～10F,故前者对机体的损伤大得多。 The efficacy and complications of percutaneous biliary drainage have been reported differently. In advanced cancer cases, the effective rate is about 90%. Percutaneous stent placement and balloon dilatation are relatively safe, the former reported complications ranging from 7% to 42%, and the latter had a success rate of 40% to 90%, with benign disease becoming more powerful. Place the plastic stent to expand the channel in the liver to 14 ~ 16F, while the metal stent only 7 ~ 10F, so the former much more damage to the body.
