Abstract
BackgroundWe evaluated the clinical significance of follow-up data, including 99mTc-DTPA galactosyl human serum albumin (99mTc-GSA) liver scintigraphy data, as prognostic indicators for jaundice-free patients with biliary atresia (BA). MethodsOf 87 patients who underwent Kasai portoenterostomy (KP) between 1991 and 2012, 45 jaundice-free patients aged 1–2 years underwent 99mTc-GSA scintigraphy and were classified into 2 groups: those who survived with a native liver (Group A, n = 34) and those who required liver transplantation (LTx) (Group B, n = 11). We compared 99mTc-GSA scintigraphy data (HH15, LHL15, and HH15/LHL15 [H/L15]) and liver function test (LFT) results between the groups. The patients underwent a second 99mTc-GSA scintigraphy at approximately 5 years of age. ResultsAll patients survived. HH15, H/L15, total bilirubin, direct bilirubin, gamma-glutamyl transpeptidase, and alanine transaminase levels were higher in Group B than in Group A (p<0.05). Total and direct bilirubin levels were associated with H/L15 (p<0.05). There were no significant changes in results between the first and second 99mTc-GSA scintigraphy in Group A. ConclusionsMid- and long-term prognoses may be predicted using 99mTc-GSA scintigraphy data and LFTs in patients aged 1–2 years. We recommend regular monitoring of postoperative data following KP, even in jaundice-free patients. Level of evidenceIII.
