ABSTRACT Our center previously reported its experience with pediatric gallbladder disease and cholecystectomies from 1980 to 1996. We aimed to determine the current clinical characteristics and risk factors for symptomatic pediatric gallbladder disease and cholecystectomies and compare these findings with our historical series.
Retrospective, cross-sectional study of children, 0 to 18 years of age, who underwent a cholecystectomy from January 2005 to October 2008.
We evaluated 404 patients: 73% girls; 39% Hispanic and 35% white. The mean age was 13.10 ± 0.91 years. The primary indications for surgery in patients 3 years or older were symptomatic cholelithiasis (53%), obstructive disease (28%), and biliary dyskinesia (16%). The median BMI percentile was 89%; 39% were classified as obese. Of the patients with nonhemolytic gallstone disease, 35% were obese and 18% were severely obese; BMI percentile was 99% or higher. Gallstone disease was associated with hemolytic disease in 23% (73/324) of patients and with obesity in 39% (126/324). Logistic regression demonstrated older age (P = .019) and Hispanic ethnicity (P < .0001) as independent risk factors for nonhemolytic gallstone disease. Compared with our historical series, children undergoing cholecystectomy are more likely to be Hispanic (P = .003) and severely obese (P < .0279).
Obesity and Hispanic ethnicity are strongly correlated with symptomatic pediatric gallbladder disease. In comparison with our historical series, hemolytic disease is no longer the predominant risk factor for symptomatic gallstone disease in children.

    ABSTRACT: Although the safety of same day discharge (SDD) after laparoscopic cholecystectomy (LC) for symptomatic cholelithiasis (SC) and biliary dyskinesia (BD) in adults has been well documented in the literature, the same data in the pediatric population are lacking. We have recently instituted a protocol for SDD after LC for SC and BD, and this study is an analysis of our initial experience. A retrospective chart review of all patients who underwent LC for BD and SC in our institution from January 2011-July 2014 was performed. A total of 227 LC were performed for SC and BD during the study period. Approximately 25% (n = 57) of patients were in the SDD group. The remaining 75% (n = 170) of patients were admitted at least overnight stay (ONS) for the following reasons: medical 16.5% (n = 28), surgery ending too late 4.1% (n = 7), or clinical care habits 79.4% (n = 135). Comparing the SDD group with ONS group, no differences were found in the complication rate, readmissions, or follow up before scheduled appointment. Length of stay was significantly less for the SDD group than for the ONS. A trend for more SDDs was observed as time elapsed from initiation of the protocol. Also, earlier completion of surgery trended toward SDD. SDD appears safe for pediatric patients undergoing LC for BD or SC. The main obstacles to discharge were time of surgery completion and clinical care habits, both of which improved as comfort level with SDD grew among the staff. Copyright © 2015 Elsevier Inc.

    ABSTRACT: Obesity is a risk factor for the formation of cholesterol gallstones and exposes patients to increased risk of gallstone-related complications and cholecystectomy. Rapid weight loss achieved by very low calorie diets or bariatric surgery is also a risk factor for cholelithiasis in obese patients, and therapy should take into account the higher prevalence of gallstones, the possibility of more frequent complications and the need for prophylactic treatment with oral ursodeoxycholic acid during weight loss. Obesity is also frequent in children and adolescents, and the burden of cholesterol cholelithiasis is increasing in this population. The chance to develop acute pancreatitis and the severity of the disease are higher in obese subjects because of specific pathogenic factors, including supersaturated bile and crystal formation, rapid weight loss, and visceral obesity. All health policies aimed at reducing the incidence of obesity worldwide will decrease the incidence of gallstones and gallstone-related complications. The pathophysiological scenarios and the therapeutic implications for obesity, gallstone disease, and pancreatitis are discussed.

    ABSTRACT: To evaluate children with gallstone in respect to demographic features, type of presentation, predisposing risk factors, laboratory features, complications, and outcome. Materials and Methods: Overall, 124 children with sonographically diagnosed gallstone were stratified into group 1 (symptomatic) and group 2 (asymptomatic). The data on demographic features, predisposing risk factors, laboratory features, complications, and outcome were collected from medical charts and compared by using convenient statistical methods.
