Insights
Children with severe constipation show impaired gallbladder motility. This gallbladder dysfunction may be a factor in functional constipation, impacting pediatric gastroenterology care.
Area of Science:
- Pediatric Gastroenterology
- Digestive System Physiology
- Medical Imaging
Background:
- Functional constipation is a common pediatric issue.
- Gallbladder motility plays a role in digestion.
- The relationship between constipation and gallbladder function in children is not well understood.
Purpose of the Study:
- To evaluate gallbladder motility in children experiencing refractory constipation.
- To compare gallbladder contractility between constipated children and healthy controls.
Main Methods:
- A cross-sectional study included 132 constipated children (ages 2-16) and 132 matched controls.
- Gallbladder contractility was assessed using ultrasonography to measure fasting and postprandial gallbladder areas.
- A gallbladder contractility index was calculated and compared between groups.
Main Results:
- Constipated children exhibited significantly larger postprandial gallbladder areas compared to controls (P=.031).
- The risk of a low gallbladder contractility index (<25%) was 5.2 times higher in constipated children (OR 5.2; 95% CI 2.5-10.81).
- Older age was associated with a protective effect on gallbladder contractility (OR 0.79; 95% CI 0.71-0.88).
Conclusions:
- Gallbladder motility disorders are present in children with severe functional constipation.
- This finding suggests a potential link between gallbladder dysfunction and pediatric functional constipation.
- Further research may elucidate the role of gallbladder motility in the pathophysiology of childhood constipation.
Objective:
The aim of this study was to evaluate gallbladder motility in constipated children.
Patients And Methods:
A cross-sectional study was conducted on pediatric patients with refractory constipation examined in a pediatric gastroenterology unit of a teaching hospital between January 2005 and August 2006. All of the patients seen during the period were included (age range, 2-16 years). The control group, matched for sex and age, was selected among patients seen at the same basic health units where patients were seen before being referred to pediatric gastroenterologists. A gallbladder contractility index was calculated based on fasting and postprandial gallbladder areas, using an ultrasonographic method. Ultrasonography studies were performed prospectively and blindly by the same physician. Measurements obtained in patients were compared with those obtained in controls.
Results:
A total of 132 constipated children and the same number of healthy controls were included in the study. Median and mean fasting gallbladder areas were similar in patients and controls. Postprandial gallbladder areas were larger in the patient group, mean +/- SD = 594.8 +/- 206.4 mm, median, 562.5 mm, than in the control group, mean +/- SD = 541.1 +/- 156.1 mm, median, 530.5 mm; P = .031. Logistic regression showed that the risk of a contractility index <25% was 5.2 times greater in patients (odds ratio [OR] 5.2; 95% confidence interval [CI] 2.5-10.81) than in controls. Age was found to be a protective factor (OR 0.79; 95% CI 0.71-0.88).
Conclusions:
Gallbladder motility disorder was identified in a group of children with severe constipation. This finding may contribute to the understanding of functional constipation in children.
