Background: Choledocholithiasis complicates 10–15% of patients undergoing cholecystectomy. While endoscopic retrograde cholangiopancreatography (ERCP) followed by cholecystectomy is common, access to ERCP is inconsistent in rural and military hospitals, highlighting the role for single-stage laparoscopic common bile duct exploration (LCBDE). Methods: We describe a technical approach for fluoroscopy-guided, wire-based transcystic LCBDE using standardized endovascular tools, the “Biliary Endovascular Toolkit”. We performed a retrospective review of five patients undergoing cholecystectomy and transcystic LCBDE at our military hospital between May 2024 and October 2025. The operative technique employed percutaneous micropuncture sheath access, fluoroscopy-guided transcystic wire cannulation of the ampulla, and balloon dilation with sphincteroplasty for stone clearance. Results: Five patients (mean age 35.4 years) underwent single-stage cholecystectomy with transcystic LCBDE. Transcystic cannulation, duodenal wire access, and ductal clearance were successful in all cases (100%), without conversion or postoperative ERCP (0%). Mean operative time was 208 min (range 161–275). No patient experienced postoperative pancreatitis, pleural complications, or other 30-day adverse events. Conclusions: The Biliary Endovascular Toolkit offers a standardized, wire-guided workflow for transcystic LCBDE using off-the-shelf equipment. This technical note provides a practical framework for general surgeons managing choledocholithiasis, particularly in resource-limited settings.
