Changes of Pudendal Nerve Terminal Movement Latency and Anorectal Function in Rectal Prolapsed Patients
摘要
Abstract
[Objectives]To evaluate the change of anorectal function in patients with rectal prolapsed by water perfusion anorec?tal manometry and pelvic floor electromyography.[Methods]A total of 60 patients with rectal prolapsed were enrolled in this study, the analgesic parameters included resting sphincter pressures, squeeze sphincter pressures, length of the anal canal and rectal sensa?tion, the results were compared with the parameters of normal population. Twenty of which completed pelvic floor electromyography ex?amination, analyzed the changes of pudendal nerve terminal movement latency (PNTML).[Results]The resting sphincter pressures, squeeze sphincter pressures of patients were lower than the normal population;The length of anal canal was shortened;The first sensa?tion and the first defecation threshold were higher than those of normal people, There was no significant change in the maximum tolera?ble threshold of rectum;pudendal nerve terminal movement latency extended more than 2.6 ms.[Conclusions]Anal resting stool and function of contraction weakened in patients of rectal prolapse, decreased sensitivity of rectal, pudendal nerve terminal movement laten?cy extended.关键词
