[Biliary lithiasis in childhood]

Area of Science:

• Pediatric Gastroenterology
• Hepatology
• General Surgery

Background:

• Gallstones (cholelithiasis) in children are less common than in adults.
• Identifying pediatric gallstone risk factors and outcomes is crucial for effective management.
• Previous studies on pediatric cholelithiasis have varied in scope and focus.

Purpose of the Study:

• To analyze the incidence, risk factors, symptoms, and outcomes of pediatric cholelithiasis.
• To evaluate the effectiveness of different management strategies, including observation versus surgery.
• To determine optimal treatment approaches for children diagnosed with gallstones.

Main Methods:

• Retrospective case series analysis of 28 pediatric patients diagnosed with cholelithiasis between 1980 and 1990.
• Identification and categorization of associated risk factors, including hereditary spherocytosis, cholestasis, and obesity.
• Clinical follow-up ranging from 1 to 5 years to assess symptoms, spontaneous resolution, and surgical intervention.

Main Results:

• Twenty-eight cases of pediatric cholelithiasis were identified, with 53.6% having identifiable risk factors.
• Hereditary spherocytosis, cholestasis, and obesity were the most frequent risk factors; non-hemolytic cholelithiasis was common.
• Abdominal pain was the most frequent symptom (8 patients); diagnosis was consistently made via echography.
• Twelve children remained asymptomatic, and six improved spontaneously, with younger age correlating with spontaneous recovery.
• Eight children required surgical intervention.

Conclusions:

• Pediatric cholelithiasis is associated with specific risk factors and can present with varied clinical courses.
• Echography is a reliable diagnostic tool for pediatric gallstones.
• A conservative management approach, including observation, may be appropriate for children under 3 years old, particularly those with milder presentations or spontaneous improvement.
