Endoscopic biliary large-balloon dilation after endoscopic sphincterotomy for the treatment of large common bile duct stones. Case report.
Common bile duct (CBD) stones extraction is usually performed by endoscopic sphincterotomy followed by removal by either a Dormia basket or extraction balloon catheter. However, some stones due to their size are not amenable to these procedures and extracorporeal or mechanical lithotripsy devices need to be used. Mechanical lithotripsy involves usage of a basket that will be inevitably destroyed which increases cost to the patient and endoscopy unit. The use of extracorporeal wave shock lithotripsy is an alternative; however it is not available widely. Reports about the use of hydrostatic large caliber balloon dilator (HLCBD) aiding in the extraction of large caliber CBD stones have concluded that is a safe and feasible therapeutic alternative. We present the case of a 25 mm x 30 mm CBD stone that could not be extracted using conventional methods. CBD dilation using HLCBD was performed after endoscopic sphincterotomy in an attempt to avoid mechanical lithotripsy.
