Core tip: Multiple lacunae exist in our current understanding of biliary strictures complicating living donor liver transplantation (LDLT). Although endoscopic management is regarded the mainstay of treatment, results are variable with multiple determinants of success. The definition of these strictures itself may need to be re-examined, from a mere narrowing on imaging studies to a more comprehensive approach which can signify functional impedance to bile flow. This review outlines the current practices of management and endeavours to incorporate novel concepts, such as functionally significant obstructions, endoscopic protocols and outcome definitions, into the wider understanding of endoscopic management for biliary strictures complicating LDLT.
