We have used a single articulated catheter to obviate the need for multiple catheters in patients with complex biliary strictures or strictures associated with small or immature tracts. Two- and three-arm articulated drains (8-14 Fr) made from segments of biliary catheters were placed in 16 patients. Nine were placed transhepatically, 6 transperitoneally through existing T-tube tracts, and 1 through a cystic duct fistula. Six malignant and 10 benign strictures were stented with various catheter configurations through a single tract. Fifteen patients had two catheter components with one articulation and 1 patient had three catheter components with two articulations. The average duration of catheter drainage was 7.0 +/- 4.2 months. Routine catheter exchanges were performed; two spontaneous occlusions occurred. In patients where internal stenting may be difficult or undesirable, articulated catheters allow satisfactory external and internal drainage of complex benign and malignant strictures through a single tract, avoiding the need for multiple transhepatic catheters.
我们使用了一种单关节导管，以避免在患有复杂胆管狭窄或与细小或不成熟管道相关的狭窄的患者中使用多个导管。由胆管导管段制成的双臂和三臂关节引流管（8-14 Fr）被放置在16例患者中。9例经肝放置，6例经现有T管通道经腹腔放置，1例经胆囊管瘘放置。通过单一通道用各种导管配置对6例恶性狭窄和10例良性狭窄进行了支架置入。15例患者有两个带有一个关节的导管组件，1例患者有三个带有两个关节的导管组件。导管引流的平均持续时间为7.0±4.2个月。进行了常规导管更换；发生了两例自发堵塞。在内部支架置入可能困难或不理想的患者中，关节导管可通过单一通道对复杂的良性和恶性狭窄进行令人满意的外部和内部引流，避免了使用多个经肝导管的需要。
