¹18 out of 19 retrograde transpapillary endosonographic cholangiopancrea-tography (ESCP) were carried out via rendezvous;

²None of these four antegrade transpapillary ESCP were “pure” antegrade. Kahaleh et al[23] used a single stent bridging both the papilla and the puncture tract, whereas Püspök et al[14] used dual stenting: a transmural stent together with a transpapillary stent;

³Retrograde cannulation of spontaneous bilio-duodenal fistula developing in the setting of postoperative duct injury, after intrahepatic bile duct injection. Similar to the methylene-blue approach, but using contrast material.
