Clearance of Cystic Duct Remnant Stones Using a SpyGlass Retrieval Basket during Single-Operator Cholangioscopy at ERCP

Abstract

AbstractExtraction of stones from a cystic duct remnant following cholecystectomy poses a significant therapeutic dilemma. Surgical intervention has historically been required due to difficulty accessing the cystic duct remnant during conventional endoscopic retrograde cholangiopancreatography. Single-operator cholangioscopy can access the cystic duct remnant, enabling electrohydraulic lithotripsy and stone extraction. Method of stone extraction has seldom been described in this developing field. Clearing duct remnant stones using guidewire placement and an extractor balloon have been reported. This is the first reported case of cystic duct remnant stone extraction using a SpyGlass retrieval basket.
