The prevalence of cholelithiasis is estimated within 0.13%and 2%of children under 19 years of age.<p>Pigment stones are the commonest type of gallstones in trong class="boldFont">childrentrong>, without recognizable predisposing factors in infants or secondary to a predisposing disease such as chronic hemolysis and ileal disease in children. In trong class="boldFont">adolescentstrong>, idiopathic cholesterol gallstones accounts for the majority, such as in adults.<p>trong class="boldFont">Gallbladder stones are found in 80 to 90%of casestrong> and common bile duct stones in 10 to 20%of cases.<p>trong class="boldFont">When common bile duct stones are foundtrong>, a choledocal cyst with anomalous pancreatobiliary duct junction needs to be excluded. Magnetic resonance cholangiopancreatography should be performed in first line.<p>trong class="boldFont">Cholecystectomytrong> is not indicated for silent gallstones, except in children with a predisposing disease such as chronic hemolysis.<p>Treatment of common bile duct stones includes trong class="boldFont">interventional radiologic, endoscopic or surgical procedurestrong>. Stone extraction may be performed at endoscopic retrograde cholangiopancreatography with or without sphincterotomy, combined with laparoscopic cholecystectomy. In children without a predisposing disease or no residual gallstones indicating a cholescystectomy, conservative management (percutaneous cholangiography with biliary drainage) may be proposed in specialised centers, especially for infants.<p>A trong class="boldFont">hepaticojejunostomytrong> is indicated in cases of choledocal cyst with anomalous pancreatobiliary duct junctions.
