Effect of Anorectal Biofeedback on Encopresis in School Aged Girls After Sexual Assault

Females who have been sexually abused anally, have a disturbed anorectal motility. They have an increased resting pressure at the lower part of the anal canal. When their rectum is suddenly distended, they tend not to have an initially increased pressure in the anal canal, and the recto-anal inhibitory reflex is markedly decreased amplitude which is caused by reflex contraction of the pelvic floor during the relaxation of the internal anal sphincter.

About this study

The cause of fecal incontinence after sexual abuse is the improper functioning of anal sphincter muscles, as a result of their damage and/or neurological changes including the disturbance perception of sensory stimuli from the anal canal. Biofeedback therapy using visual and verbal feedback techniques has emerged as an useful option in managing fecal incontinence and levator ani syndrome. The goal of biofeedback training is to improve bowel function by restoring a normal pattern of defecation.

skin trifles around the anus,
funnel shaped anus
medically stable and able to follow instructions

Exclusion criteria

sexual transmitted disease
any medical condition that affect the anus potentially such as Crohn's disease,
severe chronic constipation,
myotonic dystrophy

Treatment and study plan

Anorectal manometry

Device

, patients are instructed to isolate the anal sphincter and puborectalis muscles and improve its strength by using modified Kegel exercises in lying position with a probe in situ. Visual and verbal feedback techniques are used to reinforce the maneuvers, as they are being performed. The anal and rectal pressure changes displayed on the monitor provides visual feedback to the patient.

Primary outcomes

anorectal manometrey

Time frame: pre and after 3 months of intervention, increase in the change in the mean of initial parameters of the anal and squeeze pressure indicate improvement while decreases in the mean of first sensation and maximum tolerable volume indicate improvement

measure four variables, anal squeeze and resting pressure , first sensation and maximum tolarble volume
