Gender | Both | Age (range) | 2-16 | Eligibility criteria | Inclusion criteria | Children who have benign anal disease
Inappropriate contraction of the anal sphincter | Exclusion criteria | parents and or children given informed consent | Trial design/methodology | Phase | 4 | Kind of study | Efficacy
| Design | | Purpose of study | To address specifically the use of botulinum toxin injections into the anal sphincter of children for the diseases in which there is inappropriate contraction of the internal anal sphincter. | Primary outcomes | Manometric and ultrasound findings; improvements in pain and constipation as recorded in the doctor's record.
These would enable calculation of validated scores for constipation and pain.
In the case of anal fissure and fistula, the degree of healing would also be recorded. | | | Summary of study design, objectives, and ongoing research findings | Inappropriate contraction ( and lack of appropriate relaxation) of the internal anal sphincter is seen in a number of disease in childhood-most notably Hirschsprung's disease, certain types of constipation, anal fissue, anal fistula and post-surgery. Failure to the anal sphincter to relax makes defaecation painful, and as a consequence children often become constipated exacerbating the problem. Botulinum toxin is used in aduls for these conditions. In children it has been used only for spasticity, in order to relax over-contracted muscle. This study will address specifically the use of botulinum toxin injections into the anal sphincter of chldren for the diseases in which there is inappropriate contraction of the internal anal sphincter.
Outcome measure: Manometric and ultrasound findings. Improvements in pain and constipation as recorded in the doctor's record. These would enable calculation of validated scores for constipation and pain. In the case of anal fissure and fistula, the degree of healing would also be recorded.
