Analysis of Wire-Guided Hemostasis Introducer for Percutaneous Therapy of Bile Duct Stones.
Digestion 2018
BACKGROUND: Bile duct stones (BDS) are usually removed via endoscopic retrograde cholangiopancreatography (ERCP) or, if ERCP remains unsuccessful, percutaneous transhepatic cholangiodrainage (PTCD). However, PTCD provides limited access to large BDSs. We analyzed a modified approach of PTCD for percutaneous therapy of BDS.
METHODS: We used a modified approach of PTCD with a 13-french (Fr) hemostasis introducer for transhepatic access to BDS. Short-wired balloon or basket catheter were applied for safe removal of BDS. Patient characteristics, effectiveness, and complications were analyzed.
RESULTS: We identified 11 patients who underwent PTCD with hemostasis introducer. BDSs were either pushed forward to the duodenum (36%) or both partly pushed and extracted via hemostasis introducer (64%). In some cases, mechanical lithotripsy was necessary (45%). Complete removal of BDS was initially achieved in 36% of patients, 45% received additional PTCD, and in 19% stent implantation was performed. Finally, all BDSs could be removed. Laboratory analysis revealed significant reduction of alkaline phosphatase (p = 0.03) and C reactive protein (p = 0.03). Complications occurred only in 1 patient with post-interventional cholangitis.
CONCLUSION: Our study showed feasibility and safety of a modified PTCD with hemostasis introducer. In addition, protection of liver tissue from sharp-edged catheters and stones was achieved. Therefore, our modification revealed an innovational approach for transhepatic removal of BDS.
