Clinical Utility of Definitive Diagnostic Tests for Choledocholithiasis in Pediatric Patients with Mild Gallstone Pancreatitis.

Background: Gallstone pancreatitis was historically considered a risk factor for choledocholithiasis (CD). However, recent studies of adult patients evidenced a weak association between gallstone pancreatitis and CD. The aim of this study was to analyze this association in pediatric patients.

Development of a risk score for choledocholithiasis in pediatric patients.

Purpose: The prevalence of gallstones in children has increased over the last years. Choledocholithiasis (CD) is present in up to 30% of the cases. There is a scarcity of studies on the management of choledocholithiasis in children.

Preoperative risk factors for the early failure of the Kasai portoenterostomy in patients with biliary atresia.

Purpose: Biliary atresia is managed surgically by the Kasai portoenterostomy (KP). It has been reported by some groups that the outcomes of patients who have an early failed KP requiring a liver transplant (LTx) within the first year of life are worse than the outcomes of patients who undergo a primary LTx. The aim of this study was to identify preoperative parameters that could help predict what patients are at risk for the early failure of the procedure.

Waiting list outcome of Peld/Meld exceptions: A single-center experience in Argentina.

As PELD/MELD-based allocation policy was adopted in Argentina in 2005, a system of exception points has been in place in order to award increased waitlist priority to those patients whose severity of illness is not captured by the PELD/MELD score. We aimed to investigate the WL outcome of patients with granted PELD/MELD exceptions. A retrospective cohort study was conducted in children under 18 years old.
