¹Number of surgically altered anatomy (SAA) patients with benign biliary obstruction per total number of patients in the series; ²Number of patients with attempted drainage by stent insertion and/or balloon dilation with/without stone removal (ITT); ³Number of patients with attempted stent placement (ITT), followed by number of metal stents in parentheses;

⁴Transmural variants of HG (hepatico-esophagostomy/jejunostomy) following intrahepatic access, except when stated otherwise;

⁵Number of successful cases or complications per number of SAA patients with benign biliary obstruction;

⁶Choledochoduodenostomy with plastic stents used for transmural stone extraction in Billroth I;

⁷Transpapillary AG metal stent placed at follow-up of prior transmural intrahepatic stenting in anastomotic Strx. Tallied in the total count;

⁸AGB prior to AGS in a single case. AGS tallied as main intervention and AGB not tallied in the total count;

⁹AGB with stone removal plus temporary NBD placement in four patients. AGB of anastomotic Strx and normal cholangiogram in one each. SAA: Surgically altered anatomy; ESCP: Endosonographic cholangiopancreatography; RYG: Roux-en-Y gastrectomy; RYGB: Roux-en-Y gastric bypass; RYHJ: Roux-en-Y hepatico-jejunostomy; RV: Rendezvous; AGS: Antegrade stent insertion; AGB: Antegrade balloon dilation; HG: Hepatico-gastrostomy; ITT: Intention-to-treat; Sn: Successful cases; Cn: Complications.
