: Prior abdominal surgery is associated with increased complexity of liver transplantation (LT), but this represents a heterogenous cohort. We sought to quantify the intraoperative impact of prior abdominal surgery in LT. : Our prospective LT database (2012-2023) was analysed, comparing patients based on location of prior surgery (re-transplant, hepatobiliary, other abdominal) and method of entry (open, laparoscopic). Primary outcomes were operating time (OT) and transfusion requirements (PC). Statistical analysis included ANOVA and Chi-square tests ( p0.05) or non-RUQ surgery (OT 360.3±117.8; PC 6.02±5.6, p >0.05). : Patients with prior re-transplant, hepatobiliary and open surgery are associated with increased operating time and transfusion, whilst laparoscopic approaches did not worsen outcomes. Planning for these high-risk patients necessitates detailed pre-operative surgical assessment.
