title: [Biliary lithiasis in childhood].
abstract: We have reported 28 cases of pediatric cholelithiasis in our hospital between 1980 and 1990. We found risk factors in 15 of these cases (53.6%). The most frequent risk factors were hereditary spherocytosis, cholestasis and obesity. A high frequency of non-hemolytic cholelithiasis was noted. Lithiasis was a casual finding in 13 cases (46.4%). The most frequent symptom was nonspecific abdominal pain, which occurred in 8 patients. Diagnosis was made with echography in every case. The range of time in which the patients were followed ranged between 1-5 years. Eight children required surgery. Among the other twenty, twelve were asymptomatic and six improved spontaneously. The mean age at the moment of diagnosis was younger in the children that spontaneously recovered than in children with permanent lithiasis. Therefore, for this reason, we recommend an observation period before surgery in children younger than 3 years of age.
