    Background: The use of ultrasonography increased the frequency of diagnosis of cholelithiasis in childhood. Aim: To determine the clinical and laboratory features and follow up of children with biliary stones. Patients and methods: Twenty six children (13 male, aged 1 month to 14 years) were prospectively enrolled. Results: Nine children had a past medical history of factors potentially predisposing to stones. A clinical presentation with vomiting (50%), abdominal pain (46%) and jaundice (23%) was the most common indication for surgery. The diagnosis was based on abdominal ultrasound in all children. Cholecystectomy was performed in 15 children (laparoscopy in 13 and open surgery in 2). Children who underwent surgery were older than those who did not undeago surgery (p < 0.001), but they did not have differences in liver function tests. Eight children had pigmented stones and seven had cholesterol stones. Conclusions: In our patients, neither family history nor laboratory tests were useful in the diagnosis as well as hi the clinical decision of surgery, which was based on symptoms. The presence of cholesterol stones in a high proportion of these children may be a unique situation in Chile considering the high prevalence of this disease in the adult population.
