Risk Factors of Cholelithiasis Unrelated to Hematological Disorders in Pediatric Patients Undergoing Cholecystectomy

Carmine Noviello, Alfonso Papparella, Mercedes Romano, Giovanni Cobellis


Background: Pediatric cholelithiasis unrelated to hematological disorders is an increasing disease. We analyzed our experience in the surgical treatment of these cases to evaluate risk factors, clinical presentation, intervention and follow-up.

Methods: From January 2010 to December 2016, we retrospectively recorded all data (hematological study, familiarity, use of lithogenic drugs and parenteral nutrition) of cholecystectomies for cholelithiasis not related to hematological diseases. The body mass index (BMI) was calculated (obesity if > 25), medical treatment, surgery and follow-up were evaluated. All patients underwent ultrasound for diagnosis and major biliary tract assessment prior to surgery. All patients had a 1-year follow-up.

Results: There were twenty-four cases (eight males), with a median age of 11.2 years. Predisposing factors were familiarity in 19, use of lithogenic drugs in 5 and total parental nutrition (TPN) in 3. Median BMI was 19.8 kg/m2, with BMI > 25 kg/m2 in eight cases. Regarding the clinical presentation, 14 had acute pain in the right upper quadrant, 5 had cholecystitis and 5 had non-specific abdominal pain. The medical treatment lasted 6 months in all, except for five (three operated after 2 months and two after 12 months). Preoperative ultrasound did not show stones in the biliary tract. MRI was performed in three cases for suspected malformation of the biliary tract (negative). Laparoscopic cholecystectomy was performed in all cases: mean intervention time was 95 min. A case of postcolecystectomy syndrome was found. At follow-up, all were asymptomatic, except two (recurrent abdominal pain).

Conclusion: Main predisposing factors are familiarity and obesity. Preoperative ultrasound in our series replaced the intraoperative study of the biliary tract. Laparoscopic cholecystectomy is the gold standard.
