N2 - BACKGROUND: Complete endoscopic clearance of bile duct stones is unsuccessful in up to 30% of patients at the first attempt, necessitating further endoscopic procedures. A novel transnasal approach for extraction of these residual stones using Seldinger technique and a nasobiliary drain was evaluated. METHODS: Twenty-one patients with residual biliary stones after ERCP underwent transnasal extraction under fluoroscopy without sedation. A 0.035-inch guidewire was inserted though the previously placed nasobiliary drain into the intrahepatic ducts. The nasobiliary drain was removed, leaving the guidewire in place. A double-lumen extraction balloon was inserted over the guidewire. Multiple withdrawal maneuvers of the inflated balloon were performed to clear the bile duct. RESULTS: Residual stones were present in the extrahepatic and intrahepatic ducts in, respectively, 18 and 3 patients. The mean largest stone diameter was 5.9 mm (range, 3-12 mm). Seventeen patients had a single stone. Complete duct clearance was achieved in 17 patients (81%). The procedure was unsuccessful because of guidewire dislodgement in 3 patients and inability to pass the guidewire through the nasobiliary drain in 1 patient. There was no procedure-related complication. CONCLUSIONS: Transnasal extraction of residual biliary stones after ERCP with the Seldinger technique is safe and feasible with reasonable success and can avoid the inconvenience and cost of a repeat ERCP.
