Figure 3: Small common bile duct stone in the orificium of the papilla of Vater. The stone (3.7 mm, between markers) was detected using longitudinal EUS in a non-dilated common bile duct with hypoechoic luminal content (double head arrows, a). The stone was visible on side-viewing endoscopy in the orificium of the papilla (b). Needle knife precut was performed, leading to flow of dark bile fluid (c). Biliary sphincterotomy was completed in wire-guided standard technique (d) allowing spontaneous passage of the stone (e and f)
