Difficult Biliary Cannulation

Abstract: Endoscopic retrograde cholangiopancreatography (ERCP) is the most technically challenging procedure routinely performed by endoscopists. ERCP cannulation requires the insertion of a subcentimeter catheter through a tiny orifice at a distance of almost a meter from the operator. Only after successful cannulation of the bile duct can the real "business" of ERCP be performed (eg, sphincterotomy, stone extraction, stent placement). Selective bile duct cannulation is all the more exacting due to the occasional anat… Show more

“…In most cases, however, hematoma occured as the result of a rupture of a small calibre intrahepatic vessel caused by a guide wire. This would also explain the presence of air inside the hematoma and frequent infections, as use of guide wire is not a sterile technique [6]. In one case, the hematoma was a consequence of a traction of the extracting balloon in order to withdraw it from the biliary tree [7].…”

“…One cause could be accidental biliary tree vascular injury from the guide wire used in the procedure leading to hemorrhage. [11] Another theory suggests that during biliary clearance using a balloon, tractional pressures develop leading to rupture of small biliary blood vessels, resulting in intraparenchymal hemorrhage and subcapsular collection due to centrifugal flow of blood. [7] In our case, HSH was diagnosed 1 day after ERCP but it may take up to 10 days to be diagnosed.…”

“…One theory proposes that during biliary clearance using a balloon, tractional pressures develop, causing small biliary blood vessels to rupture, resulting in intraparenchymal hemorrhage and subcapsular collection due to centrifugal flow of blood [ 5 ]. According to another theory, the guidewire used in ERCP might cause injury to small caliber vessels in the biliary tree, resulting in injury and hemorrhage [ 7 ]. This mechanism would also justify the presence of air in the hematoma.…”
