Appendicostomy in Preschool Children with Anorectal Malformation: Successful Early Bowel Management with a High Frequency of Minor Complications

Abstract EN

Aim.

The aim of this study is to evaluate postoperatively bowel symptoms of antegrade colon enema through appendicostomies in preschool children with anorectal malformation (ARM).

Method.

164 children with ARM operated on with posterior sagittal anorectal plasty were included.

The malformations were classified according to Krickenbeck classification.

Seventeen children in preschool age had an appendicostomy.

The bowel symptoms according to the Krickenbeck follow-up were analysed pre- and postoperatively.

All complications were registered.

A questionnaire on the use of the appendicostomy was answered.

Results.

The median age (range) at the time of the appendicostomy was 4 (1–6) years.

The observation time was 5 (0.5–14) years.

The main indications for appendicostomy were incontinence and noncompliance to rectal enemas.

Postoperatively there was a significant decrease in soiling and constipation (P<0.001).

The total complication rate was 43% with infections (29%), stenosis (12%), and retrograde leakage (0).

The median time required for giving enema in the appendicostomy was 45 minutes (range: 15–120) once a day varying from 2 times/week to 3 times/day.

And: complications are less frequent than in older children.

Conclusion.

Appendicostomy in preschool children with ARM is a way to achieve fecal cleanness before school start.

The infection rate was high, but other complications are less frequent than in older children.
