Fig 1. Patient Selection and Analysis.

Fig 1

A schematic detailing patient selection and analysis is displayed. As eligibility for LPD generally centered around the absence of borderline resectable disease, open cohorts were dichotomized based on these criteria. Borderline resectable disease was anatomically defined by current NCCN criteria that include: involvement of the SMV or PV with distortion, narrowing or occlusion that can be reconstructed or abutment of the SMA not exceeding 180 degrees of the circumference.16 LPD, laparoscopic pancreaticoduodenectomy; BMI, body mass index; SMV, superior mesenteric vein; PV, portal vein; SMA, superior mesenteric artery.
