Successful endoscopic treatment of giant multiple choledocholithiasis using oral transpapillary cholangioscopy and intraductal contact lithotripsy

Abstract

The paper presents a clinical case of successful staged endoscopic treatment for giant multiple choledocholithiasis . Conventional surgery was contraindicated in the patient due to significant comorbidities and high anaesthetic risk . Contact lithotripsy was the basic minimally invasive treatment method . It was combined with balloon dilatation of the endoscopic papillosphincterotomy area and mechanical intraductal lithotripsy . Contact lithotripsy in oral transpapillary cholangioscopy , in combination with other modern methods for endoscopic treatment of choledocholithiasis , has a good technical and clinical effect even with giant calculi .
