Insights
Colonic washout enemas effectively treat persistent constipation in children with dysfunctional voiding when oral laxatives fail. This method normalized rectal diameter and improved symptoms in most patients, offering a viable treatment option.
Area of Science:
- Pediatric Gastroenterology
- Urology
- Colorectal Surgery
Background:
- Dysfunctional voiding in children often coexists with persistent constipation and rectal dilatation.
- Standard oral laxative therapies may be insufficient for managing severe constipation in this population.
Purpose of the Study:
- To evaluate the efficacy and safety of colonic washout enemas for children with persistent constipation and dysfunctional voiding.
- To assess the impact of washout enemas on rectal diameter and associated symptoms.
Main Methods:
- Fifty children with dysfunctional voiding and rectal dilatation, unresponsive to oral laxatives, received colonic washout enemas.
- Treatment involved retrograde rectal filling with water (20 mL/kg), initially daily, then 3 times weekly for 6-12 months.
- Rectal diameter was assessed via ultrasound, and symptom relief was monitored over a 6-month follow-up period.
Main Results:
- Thirty children achieved resolution of urinary tract infections, and 20 experienced partial symptom relief.
- All patients demonstrated normalized rectal diameter on ultrasound post-treatment.
- Washout therapy was successfully discontinued in 33 patients; 17 required intermittent enemas for relapse prevention. Minimal pain was reported, with no significant adverse effects.
Conclusions:
- Colonic washout enemas represent a successful therapeutic option for children with dysfunctional voiding and constipation refractory to oral laxatives.
- The treatment normalizes rectal diameter and can lead to sustained symptom improvement, potentially reducing the need for long-term laxative use.
Objectives:
To describe the use of colonic washout enemas for persistent constipation in children treated for dysfunctional voiding by cognitive and biofeedback training.
Methods:
We treated 50 children, who had dysfunctional voiding and persistent dilatation of the rectum notwithstanding adequate oral laxatives, with colonic washout enemas. We performed retrograde filling of the rectum with 20 mL/kg water, starting once daily for 2 weeks, then 3 times per week for 6 to 12 months.
Results:
During the 6-month follow-up, 30 children were free from urinary tract infections. In 20 children we observed partial relief of complaints. On ultrasound all children showed a normalized diameter of the rectum. In 33 patients washout treatment could be stopped with continuing success. Relapse of a distended rectum triggered the need for chronic intermittent enema therapy in 17 patients. A few patients reported pain during enema treatment; otherwise, we noted no counter-effect.
Conclusions:
Dysfunctional voiding combined with constipation in children can be cured by washout enemas if oral laxatives fail.
