Prognostic significance of preoperative imaging in recipients of living donor liver transplantation for XXXX .

@entity1 @entity5462 @entity5 @entity1575 @entity157
BACKGROUND: Accurate preoperative imaging is an important aspect of @entity1 evaluation before liver transplantation for @entity157 ( @entity157 ) because the size and number of @entity5 are indicators of posttransplant prognosis. This study aimed to evaluate the preoperative detectability of @entity157 and clarify the role of preoperative assessment on prognosis after living donor liver transplantation (LDLT). METHODS: Eighty-one @entity1 who underwent LDLT for @entity157 accompanied by @entity1575 were reviewed. A total of 149 nodules were pathologically diagnosed as @entity5462 . The pathologic findings were correlated with preoperative results from contrast-enhanced computed tomography, magnetic resonance imaging, and computed tomography with angiography. RESULTS: The detectability of small @entity5462 (<1 cm) and well-differentiated @entity5462 was significantly reduced. Forty-six of 81 cases were preoperatively judged to meet the Milan criteria, although 16 of these failed to meet the criteria according to postoperative pathologic examination. However, recurrence-free survival in the 16 cases was similar to that in the 30 cases who met the criteria. CONCLUSIONS: The preoperative diagnostic accuracy of radiologic imaging for small-sized, well-differentiated @entity5462 requires improvement. However, these undetected @entity5462 have little effect on prognosis after LDLT, and current imaging modalities therefore provide acceptable methods of preoperative LDLT evaluation.
