| Abstract |
PURPOSE
Chronic constipation is not uncommon even in children. Recently biofeedback treatment (BT) is considered as a useful modality in the treatment of various types of constipation. The aim of this study was to evaulate the effectiveness of BT in children with chronic constipation.
METHODS
We reviewed 24 cases of childhood constipation (17 boys, 7 girls) who visited the Jinju Hakmoon colorectal surgery clinic and GNUH1 between April, 2001 and September, 2002. Balloon-mediated anorectal manometry system was used for BT. The effects of therapy was assessed by bowel movement, defecation time, fecal soiling and balloon evacuation test in the early course of therapy. The long term follow up survey was done by telephone interview at January 2003 and the effects of therapy was assessed by bowel movement, defecation time, fecal soiling and parents' satisfaction.
RESULTS
Patients received the BT for the three times on average, and as the result of the therapy, 20 patients experienced disappearance of symptoms (87%) or at least improvement of symptoms. In terms of manometric values, the mean resting pressure was 113.4 mmHg before the BT, but decreased to 86.3 mmHg after the BT (P=0.0012). Mean pushing pressure dropped to 85.98 mmHg from 130.45 mmHg (P=<0.0001).
Mean sensitivity decreased from 55 ml to 35 ml (P=0.0053).
Mean compliance decreased from 20.28 H2O/cm to 4.21 H2O/cm (P=0.0015). 13 patients (76%) showed disappearance or improvement of symptoms in the long term follow up.
CONCLUSIONS
The Balloon mediated biofeedback therapy is effective in children with chronic constipation. It is safe, easy to administer and also improve symptoms and objective parameters of anorectal function. Balloon mediated biofeedback therapy could be the first-line therapy in child patient with chronic constipation who failed conservative management. |
