Institutional review board statement: All procedures performed in studies involving human participants were in accordance with the ethical standards of the Chiba University Hospital. Because of the retrospective design, approval of the ethic commission was not always required.
Informed consent statement: Informed consent was obtained from all individual participants as to the percutaneous biliary drainage as part of the treatment for biliary disorders.
Conflict-of-interest statement: We have no potential conflicts of interest to declare.
Data sharing statement: Technical appendix, statistical code, and dataset available from the corresponding author at h-shimizu@faculty.chiba-u.jp. Consent was not obtained from the study participants because the present data are retrospective, de-identified, and anonymized; therefore, the risk of identification is low.

Core Tip

Core tip: Percutaneous transhepatic biliary drainage (PTBD) offers a valuable alternative for access to the biliary system when endoscopic biliary drainage is impossible or infeasible. PTBD is generally performed in jaundiced patients with dilated bile ducts (BDs). However, some patients inevitably require PTBD even in the absence of dilated BD. Achieving needle access to the non-dilated BD is a challenging procedure. The present study reported on detailed technical aspects of peripheral portal vein-oriented BD puncture for PTBD in patients with non-dilated BDs, and also examined the safety and success rates of this procedure.
