Challenges and outcomes of pancreato-duodenectomy in portal annular pancreas: A single center experience with a systematic review of the literature.

ABSTRACT:

Backgrounds/aims

Portal annular pancreas (PAP) is an anomaly where pancreatic tissue surrounds the portal vein (PV). We present a case series from our institution and a systematic review of PAP patients who underwent pancreatoduodenectomy (PD).
