Purpose: For children with upper abdominal pain and evaluation for acalculous biliary disease, laparoscopic cholecystectomy is an accepted treatment with inconsistent outcomes. The purpose of this study was to identify predictors of outcomes. Methods: One hundred sixty-seven children underwent laparoscopic cholecystectomy at a single children's hospital. Radiographic findings, histopathology, family history, and demographics (sex, age, height, weight, body mass index-for-age percentile) were evaluated as predictors of postoperative symptomatic resolution using a binomial probability model. The data for radiologic studies and pathologic specimens were obtained via re-review in a blinded fashion. Results: Of 167 children, 43 (25.7%) had a preoperative diagnosis of biliary dyskinesia and 41 (95.3%) had documented follow-up. Mean follow-up was 8.4 months. Twenty-eight patients (68.3%) had symptom resolution. Ejection fraction less than or equal to 15%, pain upon cholecystokinin injection, and a family history of biliary disease were not predictors of symptomatic resolution. Nonoverweight patients (body mass index-for-age
