Sensitivity and predictive value of ultrasound in pediatric cholecystitis

Laparoscopic Cholecystectomy for Symptomatic Cholecystic Disease in Children: Defining Surgical Timing

Background: Laparoscopic cholecystectomy (LC) is the standard of care for gallbladder (GB) pathologies. We evaluated clinical, ultrasonographic (US) data as well as histopathological findings in children affected with symptomatic cholecystic disease (SCD) who underwent LC, with the aim of defining surgical timing. Methods: We reviewed our cases who underwent elective LC (ELC) or urgent LC (ULC). Clinical, US, surgical and histological features were used to create different risk scores. Results: We considered 26 children (17 ELC/9 ULC). US signs were not different in the two groups (p > 0.05). Operating times were longer in ELC than in ULC (p = 0.01). Histopathological evaluation revealed fibrosis and atrophy in both ELC and ULC. The clinical risk score was higher in ELC compared to ULC (p < 0.001). An increased operative risk score was noted in patients with systemic inflammatory signs (OR1.98), lithotherapy (OR1.4.3) and wall thickening ≥3 mm (OR2.6). An increased histopathological risk score was detected in children with symptom duration >7 days (OR3.61), concomitant hematological disease (OR1.23) and lithotherapy (OR3.61). Conclusion: Criteria adopted in adults cannot be adopted to detect the severity of GB damage in children. A dedicated clinical and US score is mandatory to define the most appropriate surgical timing.

The increasing incidence of gallbladder disease in children: A 20year perspective

OBJECTIVE

The incidence of cholecystectomy in the pediatric population has increased over the last 20years but has not been described in a Canadian population. We conducted the first province-wide study to describe the incidence of cholecystectomy in children in Ontario.

STUDY DESIGN

A population-based, retrospective cohort using administrative databases in Ontario, Canada, was conducted. We included patients less than 18years of age who underwent cholecystectomy from 1993 to 2012. Trends in rates of cholecystectomy were assessed with the Cochrane-Armitage test.

RESULTS

There were a total of 6040 pediatric cholecystectomies performed over the study period in Ontario. The mean age was 14.3years, and 79.6% of patients were females. The crude incidence per 100,000 person-years increased from 8.8 to 13.0 (p<0.001) from 1993 96-2009-12, respectively. The sex-specific incidence showed a larger increase in the female population from 14.7 to 21.1 per 100,000 person-years (p<0.001). The vast majority (82%) of surgeries were performed in 13-17year olds and were largely performed in the community (>75%).

CONCLUSIONS

There has been a significant rise in the incidence of pediatric cholecystectomy in Ontario over the last 20years. The majority of surgeries are performed in the community, and pediatricians will likely see an increase of gallbladder disease in practice.
