Background: MHV reconstruction is essential to avoid anterior sector congestion in adult live donor liver transplantation (LDLT) using a modified right lobe graft.Aims: The objective of this study is to evaluate the graft and patient outcomes with single orifice outflow reconstruction technique (SORT) (RHV + neo-MHV combined reconstruction on IVC) vs. dual outflow reconstruction technique (DORT) (RHV and neo-MHV separately reconstructed on IVC) in a modified right lobe LDLT.Methods: Prospectively collected data of consecutive patients undergoing LDLT from June 2011 to August 2018 were analyzed. The patients were divided into two groups: SORT (n = 207) and DORT (n = 108). The perioperative morbidity and mortality were compared between two groups.Results: The two groups were comparable in baseline preoperative characteristics. Intraoperatively, warm ischemia time (27 vs. 45 min, p < 0.001), anhepatic phase (132 vs. 159 min, p < 0.001), and operative time (680 vs. 840 min, p < 0.001) were significantly shorter in SORT group. SORT group also had significantly lower GRWR (0.92 vs. 1.06, p < 0.001) and higher portal flow (2.4 vs. 2.7 L/min, p = 0.02). Postoperatively, SORT group had lower peak AST (177 vs. 209 IU/L, p < 0.001), ALT (163 vs. 189 IU/L, p = 0.004), creatinine levels (0.98 vs. 1.10, p = 0.01), rate of severe sepsis (13.7% vs. 22.9%, p = 0.03), major morbidity (50.7% vs. 62.6%, p = 0.03), shorter ICU (9 vs. 14 days, p < 0.001), and hospital stay (21 vs. 26 days, p = 0.03). Overall survival rates were comparable.Conclusion: A SORT leads to improved early graft function and perioperative morbidity in modified right lobe LDLT in spite of having lower GRWR and higher portal flow.
