Duché M, Ducot B, Ackermann O, Jacquemin E, Bernard O. Progression to high-risk gastroesophageal varices in children with biliary atresia with low-risk signs at first endoscopy. J Pediatr Gastroenterol Nutr. 2015 May; 60(5):664-8.

Abstract
OBJECTIVES:

Biliary atresia carries a risk of bleeding because of portal hypertension. Our goal was to define the factors associated with the emergence of endoscopic signs carrying a high risk of bleeding in children who did not display these signs at the first upper gastrointestinal endoscopy.

METHODS:
From 1989 to 2013, a total of 225 children with low-risk signs at the first endoscopic examination underwent ≥2 upper gastrointestinal endoscopic examinations. The emergence of high-risk gastroesophageal varices was observed in 76 children in the 10 years following the first endoscopic examination. A survival study using the occurrence of high-risk varices as an event was performed to identify factors related to the emergence of these varices and to describe the probability of their emergence in 2 groups of children ages older than 18 months and 18 months or younger at the time of the first endoscopy.

RESULTS:
High total serum bilirubin concentration, young age, and high number/grade of esophageal varices at the first endoscopy were significantly related to the emergence of high-risk varices. The probability of the emergence of high-risk signs was higher and these signs appeared faster in infants 12 months of age or younger and/or when the first endoscopic examination displayed >1 grade 1 or grade 2 varices. Progression to high-risk varices was also related to bilirubinemia in children older than 18 months at the first endoscopy.

CONCLUSIONS:
The results allow defining a program of repeat endoscopies to detect high-risk varices and to discuss endoscopic primary prophylaxis of bleeding or hasten liver transplantation when these signs are found.
