¹Number of surgically altered anatomy (SAA) patients with malignant biliary obstruction per total number of patients in the series;

²Number of patients with attempted stent placement (ITT), followed by number of metal stents in parentheses;

³Transmural variants of HG (hepatico-esophagostomy/jejunostomy) following intrahepatic access, except when stated otherwise;

⁴Number of successful cases or complications per number of SAA patients with malignant biliary obstruction;

⁵Initial plastic stent replaced at follow-up. Only final stent tallied in the total count;

⁶Additional hepato-esophageal plastic stent combined with AG metal stent in recurrent gastric cancer after RYG. Not tallied in the total count;

⁷Choledochoduodenostomy after palliative gastrojejunostomy. SAA: Surgically altered anatomy; ESCP: Endosonographic cholangiopancreatography; RYG: Roux-en-Y gastrectomy; RYHJ: Roux-en-Y hepatico-jejunostomy; PD: Pancreatico-duodenectomy; Gast: Gastric; Panc: Pancreatic; RV: Rendezvous; AG: Antegrade; HG: Hepatico-gastrostomy; ITT: Intention-to-treat; Sn: Successful cases; Cn: Complications.
