Insights
Defecography is a valuable tool for diagnosing pelvic floor disorders in children with constipation. This safe and feasible screening method helps identify evacuatory issues in childhood constipation.
Area of Science:
- Gastroenterology
- Pediatric Surgery
- Pelvic Floor Imaging
Background:
- Pelvic floor disorders and evacuation disorders are increasingly understood.
- Defecography is established in adults but underutilized in pediatrics.
- Childhood constipation often involves complex pelvic floor dysfunction.
Purpose of the Study:
- To evaluate the utility of defecography in diagnosing childhood constipation.
- To assess the safety and feasibility of defecography in pediatric patients.
- To determine if defecography can serve as a screening tool for pediatric constipation.
Main Methods:
- Defecography was performed on 8 healthy volunteers.
- Defecography was conducted on 96 children diagnosed with constipation.
- Data analysis focused on identifying pelvic floor abnormalities related to evacuation.
Main Results:
- Defecography successfully identified evacuatory pelvic floor disorders in children with constipation.
- The procedure demonstrated safety and feasibility in the pediatric population.
- Results support the use of defecography for screening childhood constipation.
Conclusions:
- Defecography is a valuable diagnostic method for childhood constipation.
- The technique is safe and feasible for pediatric use.
- Defecography should be considered a screening tool for pediatric constipation.
Abstract:
Defecography is one of the most valuable methods for the evaluation of pelvic floor disorders. Interest in this technique has rapidly expanded owing to its increased understanding of the multifactorial pathophysiology involving evacuation disorders. The value of defecography has reached a consensus in adulthood but is still limited in childhood. In this study, defecography was carried out in 8 volunteers and 96 constipation children. The results revealed that defecography can help to identify evacuatory pelvic floor disorders in childhood constipation. It is safe and feasible and should be used as a screening method for childhood constipation.
