Aims abnormalities of external anal sphincter electromyography (eas-emg) characterize multiple system atrophy (msa) and focal cauda equina or conus medullaris lesions. This study is designed to determine whether and how diabetic polyneuropathy (dpn) affects eas as compared to the abnormalities seen in msa. Objective to explore the value of anal sphincter electromyography (asemg), orthostatic hypotension (oh), and dizziness in diagnosing multiple system atrophy (msa). Method the characteristics of asemg and oh were compared among patients with dizziness (msa and non-msa), patients without oh (msa and non-msa), and patients with probable msa (oh and non-oh). The term sphincter atrophy refers mostly to external anal sphincter (eas) atrophy, as the eas is the most important factor for maintaining fecal continence. Anal sphincter relaxation or contraction during rectal disten- tion, amplitude and duration of rebound contractions, and frequency and amplitude of anal resting pressure oscilla- tions. Anal sphincter electromyography six patients with myotonic md consented to the performance of emg studies of the anal sphincter. Sphincter electromyography (emg) was carried out in 126 patients with suspected msa with review of their case notes up to 2 years later. Of those in whom a diagnosis of msa was made, 82 had had an abnormal sphincter emg. Background atrophy of the external anal sphincter, a pathologic muscle volume anomaly associated with fecal incontinence, has been shown to be a negative predictor of the outcome of surgery for defects of the external anal sphincter. It is unclear whether external anal sphincter atrophy also affects the outcome of sacral nerve stimulation for fecal incontinence. internal anal sphincter atrophy in patients with systemic sclerosis nora m.

Com objectives ssc is a connective tissue, multisystem disorder of unknown aetiology. Both constipation and fecal incontinence are prominent lower gastrointestinal tract (lgit) dysfunctions that occur frequently in multiple system atrophy (msa). We investigated the mechanism of constipation and fecal incontinence in msa. External phased-array mri is comparable to endoanal mri in depicting external anal sphincter atrophy and, thereby, in selecting patients for anal sphincter repair. Because results among interpreters varied considerably depending on the experience level, both techniques can be recommended in the diagnostic workup of fecal incontinence only if sufficient experience is available.
