Abstract

BACKGROUND AND STUDY AIMS:

Cholestatic jaundice in infants is a serious condition, requiring timely and accurate diagnostic evaluation. Our aim was to determine the safety and diagnostic efficacy of endoscopic retrograde cholangiopancreatography (ERCP) in the diagnosis of cholestatic liver disease in neonates and infants.

PATIENTS AND METHODS:

ERCP procedures in cholestatic infants performed in our endoscopy unit between December 1998 and March 2008 were reviewed retrospectively (n = 104 children, 48 boys, 56 girls; mean age 7 weeks, range 3 - 25 weeks; mean weight 4.05 kg, range 1.5 - 4.8 kg). Endoscopic findings were compared with final diagnoses. Statistical analysis was performed and sensitivity, specificity, positive (PPV) and negative (NPV) predictive values of ERCP were calculated both separately for each diagnosis and on aggregate.

RESULTS:

Cannulation of the papilla was successful in 95 of 104 patients (success rate 91.3 %). Biliary atresia of any type was found in 51 children (53.7 %), with a sensitivity of 86 %, a specificity of 94 %, a PPV of 96 %, and a NPV of 100 %. Choledochal cysts were found in seven children (7.4 %), with a sensitivity of 100 %, a specificity of 90 %, PPV of 86 %, and NPV of 100 %. Biliary stones were found in seven patients (7.4 %). Other structural pathology was found in six patients, and no abnormality was seen in 24 patients. No severe complications occurred during or after ERCP.

CONCLUSIONS:

ERCP in cholestatic infants, when performed in an expert center, is a safe and reliable procedure that can detect biliary tract abnormalities (e. g. biliary atresia, bile duct stones or choledochal cysts) with high sensitivity and specificity. Laparotomies can be prevented in infants by demonstrating normal patency of the biliary tract by ERCP or by magnetic resonance cholangiography if improvements in this technique are made.
