Fluoroscopic “Candy Sign” of the Metallic Stent in Endoscopic Ultrasound-Guided Transmural Drainage

Abstract

Endoscopic ultrasound-guided intervention is the emerging procedure for many pancreatico-biliary disorders. It is considered now as the standard line of drainage of pancreatic and peri-pancreatic fluid collections. It is also considered the first option for biliary decompression in patients with distal malignant biliary obstruction as a salvage method for failed or unsuitable Endoscopic Retrograde Chola ngio-pancr eatog raphy (ERCP). Here, we present two cases: the first is a case of endoscopic ultrasound (EUS)-guided cystogastrostomy and the second is an EUS-guided chole docho duode nosto my (CDS), both showed a unique sign called the Candy signs, which has several explanations
