The presence of neuropathy has been shown to affect surgical outcomes adversely. Latency studies are of dubious value in assessing neuropathy; needle electromyography is the gold standard test. The relationship between these two tests and the symptoms of fecal incontinence has not been studied. METHOD: A cohort of 57 patients underwent neurologic and symptom assessment using latency studies, concentric and single-fiber electromyography, and symptom assessment using the Cleveland Clinic Scoring System. RESULTS: There was a significant correlation between left mean fiber density and Cleveland Clinic Scoring (correlation: 0.32, P = 0.02) but not between right or left latency studies. CONCLUSION: Single-fiber electromyography gave relevant results that could be obtained easily on modern equipment. Latency values were not reliable.展开更多
