Chronic idiopathic constipation is most common cause of Constipation in childhood with numerous cases in Egypt. Numerous conservative measures were tried but many fail. Surgical options include Longitudinal Myectomy of the muscle or injection of Botulinum toxin. Objectives: Comparative study between Botulinum toxin injection and Myectomy in treatment of Idiopathic Constipation

Additional Information

Official title Comparative Study Between Botulinum Toxin Injection and Myectomy in Treatment of Idiopathic Constipation in Children
Principal investigator Mohamed Seoudi
Description Functional constipation (chronic idiopathic constipation) is most common cause of constipation in pediatric age group. Many cases try conservative treatment but fail to respond. These cases are treated by surgical longitudinal myectomy of the anal sphincter. Now, there have been many trials of trying injection of botulinum toxin to relax the sphincter as a treatment of functional/idiopathic constipation. In this study, the investigators will compare the results of botulinum toxin injection versus surgical myectomy to treat functional/idiopathic constipation in children.
