Background: Ochsner Unit has been assigning the potential recipient with surgical complexity category since 2015 to preempt surgical risk .

Aim: To review outcomes after the implementation of a surgical complexity scoring system.

Methods: A retrospective review of 400 consecutive liver transplants between Jan 2015 -Dec 2016. Patients were stratified into: A (low risk, n=268), B (moderate risk, n=91), and C (high risk, n=41) categories. Cox regression was used to analyze factors associated with surgical risk. Subgroup analyses were performed.

Results: Recipient BMI >30 (-HR 1.16; 95%CI 1.01-1.32), >5 Days of dialysis post-transplant (HR1.05; 95%CI 1.01-1.10), total surgery time (HR 2.90; 95%CI 1.13-7.73), low pRBC transfusion (HR-0.80; 95%CI 0.67-0.96), Low MELD (HR-0.69; 95%CI 0.57-0.84) and waitlist time (HR 0.99; 95%CI 0.98-0.99) were significant factors associated with graft survival.

High risk (C) recipients were likely to have longer ICU stay (p=0.02), longer surgical time (p=0.02). Low risk (A) recipients were likely to have higher DRI organ (p<0.001), macro-steatotic >10% (p=0.01) and micro-steatotic liver >10% (p=0.01). Incidence of EAD (–OR 0.53; 95%CI -0.25-1.130; p= 0.28) biliary complications (OR-0.71; 95%CI 0.37-1.31; p=0.51), HAS (OR- 0.49; 95%CI 0.22-1.11; p= 0.16) and HAT (OR 0.22; 95%CI NA; p= 0.24) were not significant across all complexity grades. The survival in high risk cohort was optimal at 30 d, 90 d and 1 Y post LT. Conclusion: We have developed a novel system of recipient surgical complexity assessment. Prospective outcome measures show these distinct groups have different resource requirements.
