通过ERCP（endoscopic retrograde cholangiopancreatography），当ERCP失败时，经皮经肝路径植入支撑架进入12指肠。支撑架进入12指肠可能引起并发症，如支撑架嵌塞（stent impaction）、穿透或穿孔相关的瘘或脓肿【1-6】。
After percutaneous access of the intrahepatic biliary duct was achieved, a long 10Fr sheath was positioned in the common bile duct over an 0.035” guidewire with a second 0.018” guidewire positioned to gain access into the plastic stent.
