非创伤性桡神经麻痹伴神经多段束带样病变临床罕见，其病因可能是神经外膜、束膜内的血管炎；手术治疗效果良好。

Results: Large number of immunoreactive fibres was detected in lamina propria and muscularis mucosae. Strong staining of ganglion cells in the Auerbach's and the Meissner's plexus were observed on the normal specimens. There was very little or no immunoreactive fibre in the lamina propria and muscularis mucosae of the aganglionic bowel. However there was strong immunoreactivity in the perineurium of the hypertrophic nerve trunks in the submucosal and intramural layers of aganglionic segments.
