AbstractThe morbidity and mortality of cholecystectomy can increase to 10% in high surgical risk patients. The technique for percutaneous cholecystolithotomy consists of 3 steps: (1) percutaneous cholecystostomy, (2) tract dilation and cholecystolithotomy, and (3) tract evaluation and catheter removal. Cholecystoscopy is critical in guiding the lithotripsy probe for fragmentation of large stones and is useful for locating small stone fragments not seen in cholangiography. Cholecystoscopy is also useful for assessing ambiguous lesions and in distinguishing between stone vs debris or mass. Technical success rate of percutaneous cholecystolithotomy using cholecystoscopy ranges from 93% to 100%. Procedure related complication rate has been reported as 4%-15%. The most common complication is bile leak during the procedure or after catheter removal. Although recurrence rate of gallstones has been reported up to 40%, the symptom recurrence rate is much lower. Therefore, percutaneous cholecystolithotomy using cholecystoscopy can be an alternative to cholecystectomy in high surgical risk patients with symptomatic gallstones.Copyright © 2019 Elsevier Inc.
