Small sphincterotomy combined with endoscopic papillary large balloon dilation vs sphincterotomy alone for removal of common bile duct stones

Figure 1 Fluoroscopic view of large-balloon dilatation following limited sphincterotomy. A: Cholangiogram demonstrating two large stones within the dilated bile duct; B: A large balloon inflated across the papilla over the guidewire; C: The cholangiogram following complete stone removal showed no residual filling defect in the bile duct; D: The placement of a nasobiliary drainage tube.

Figure 2 Endoscopic view of large-balloon dilation following limited sphincterotomy. A: Endoscopic small sphincterotomy; B: A large balloon inflated across the papilla; C: Markedly dilated papilla following large-balloon dilation; D: A large stone extracted using a retrieval balloon catheter through the dilated papilla.
