A Study of the Effect of Cutaneous Electric Stimulation on the Structure of The Anal Sphincter of Rat After Induction of Anal Muscle Injury

Abstract

It is well known that the muscles of the anus perform a critical role in maintaining continence. Any defect in their structure can negatively affect the physiological control of feces. Modalities of treatments applied to cases of fecal incontinence depend on their efficiency. The most recent one is the anorectal electro-stimulation, which proved to have a general improving effect on the anal musculature. 30 adult female albino rats (weighing 180-250 grams) were divided into four groups. The rats were divided into the following groups: Group (I): Twelve female adult rats were subdivided into two subgroups six in each. IA: control group. IB: sham group. Group (II): Six adult female rats were subjected to induction of anal sphincter injury, and then histological specimens were taken after three days. Group (III): Six adult female rats were subjected to induction of anal sphincter injury and were left for spontaneous healing for three weeks. Group (IV): Six adult female rats were subjected to induction of anal sphincter injury and then received five sessions per week of cutaneous anal electric stimulation for three weeks (Hugo et al., 2017).
