    Procurement-related liver injury for transplantation: an analysis of the risk factors and consequences in an Australian transplant centre
    Walcott, J ; Fink, M ; Ealing, I ; Christophi, C ; Muralidharan, V (WILEY, 2021-12)
    BACKGROUND: Liver transplantation is an established treatment for liver failure, and its success relies on the quality of the donated organ amongst other factors. Studies on procurement-related liver injury (PRLI) are few and some may not apply to modern-day practice. This is the first Australian study examining risk factors and consequences of PRLI. METHOD: The Victorian Liver Transplant Unit database was examined for deceased liver donors from 2010 to 2017. Information regarding the donor, retrieval and subsequent transplantation was obtained. PRLI details were sought from the 'organ retrieval report form'. PRLI risk factors and their complications were analysed. RESULTS: A total of 420 transplants were included, with 45 injuries in 44 livers (10%), and significant injuries were observed in 4%. Variant anatomy was associated with an increased risk of PRLI (11% vs. 2%, p < 0.001). Complication rates were not significantly different between livers with and without PRLI however a reduction in early graft survival was observed. CONCLUSION: This study shows that PRLI is common, and that variant anatomy is associated with an increased risk of injury. Appropriate feedback and benchmarking are important to maintain a high quality in donor surgery.

    Reduction in post-operative pancreatic fistula with polyethylene glycol and recombinant human albumin sealant following stapled distal pancreatectomy
    Privett, BJ ; Perini, MV ; Weinberg, L ; Fink, MA ; Muralidharan, V ; Lee, E ; Starkey, G ; Jones, R ; Lin, Y-J ; Nikfarjam, M (WILEY, 2021-11)
    BACKGROUND: Postoperative pancreatic fistula (POPF) remains a significant cause of morbidity in patients undergoing distal pancreatectomy (DP). The use of polyethylene glycol (PEG) and recombinant human albumin sealant gel applied to the transected pancreatic margin in DP may reduce POPF rates and was assessed. METHODS: A retrospective single centre cohort study of patient undergoing DP at an Australian high volume tertiary institution between January 2015 and January 2021. Rates of POPF in patients undergoing stapled pancreatic transection with PEG sealant were compared to other methods. RESULTS: A total of 54 cases were identified for analysis, with 16 undergoing stapled DP combined with staple line application of PEG (PEG group). Most patients in the control group had stapled DP 92% (35 of 38), with 47% (18 of 38) combined with a reinforcing buttress, with or without the use other glue types. Overall, 28 of 54 (52%) developed a POPF, with a significantly lower rate in the PEG group (3 of 16 vs. 25 of 38 in the Control group; p = 0.003). Clinically significant Grade B/C POPF was lower in the PEG group (0 of 16 vs. 9 of 28 in the Control group; p = 0.045), and patients in the PEG group had a shorter median (range) length of hospital stay (6 [4-14] days vs. 10 [6-41] days p = 0.04). CONCLUSION: Stapled DP with the application of PEG and recombinant human albumin sealant to the transection line appears to be associated with a lower rate of clinically significant POPF.
