The major limitations of biliary extracorporeal shock wave lithotripsy (ESWL) relate to adequate stone fragmentation and clearance of the stone fragments. We hypothesized the removal of small fragments with concomitant catheter cholecystostomy during ESWL would improve its efficacy. ESWL with aspiration or flushing through three different cholecystostomy catheters was performed on pigs with surgically implanted gallstones. Twenty-two percent and 46% of the pre-ESWL stone weight were aspirated through the 10 and 12 French catheters respectively. The clearance, size, and visualization of fragments was not significantly different between any of the groups. No significant post-mortem tissue or catheter damage was found. Catheter aspiration is a safe and effective method of removing gallstone fragments during biliary ESWL, but it does not improve stone fragmentation, stone clearance, or visualization of other fragments.
胆道体外冲击波碎石术（ESWL）的主要局限性与结石的充分碎裂以及碎石片的清除有关。我们推测在ESWL期间通过伴随的导管胆囊造口术清除小碎片会提高其疗效。对 surgically implanted 有胆结石的猪进行了通过三种不同胆囊造口术导管进行抽吸或冲洗的ESWL。分别通过10和12法式导管吸出了ESWL术前结石重量的22%和46%。各组之间碎片的清除、大小和可视化没有显著差异。未发现明显的死后组织或导管损伤。导管抽吸是在胆道ESWL期间清除胆结石碎片的一种安全有效的方法，但它并不能改善结石碎裂、结石清除或其他碎片的可视化。 （注：“surgically implanted”这里可能表述有误，推测是“手术植入的”意思，但原词不太准确）
