【摘要】：【目的】通过研究肛管直肠动力及阴部神经潜伏期的变化,探讨直肠脱垂患者肛管功能的异常,为临床制定治疗方式提供合理依据。【方法】回顾分析60例诊断为直肠脱垂患者水灌注肛管直肠压力数据,分析肛管静息压、肛管功能长度、肛管最大收缩压、直肠黏膜初始感觉、初始排便感觉及最大耐受阈值,并将检查结果与正常人群参数比较;其中20例患者完成盆底肌电图检查,分析阴部神经潜伏期的变化。【结果】直肠脱垂患者肛管静息压力、收缩压力均低于正常人群(P0.05);肛管功能长度缩短(P0.05);直肠初始感觉及初始排便阈值高于正常人群(P0.05),直肠最大耐受阈值无明显变化;直肠脱垂患者阴部神经潜伏期延长超过2.6 ms。【结论】直肠脱垂患者肛管静息持便及收缩功能减弱,直肠黏膜敏感性下降,直肠黏膜下神经丛反应降低,阴部神经潜伏期延长。
[Abstract]:[objective] to investigate the abnormality of anal canal function in patients with rectal prolapse by studying the changes of anorectal motility and latent period of pudendal nerve. [methods] 60 patients with rectal prolapse were analyzed retrospectively, including anal resting pressure, functional length of anal canal and maximum systolic pressure of anal canal. Rectal mucosal initial sensation, initial defecation sensation and maximum tolerance threshold were compared with the normal population parameters, and 20 patients completed pelvic floor electromyography examination. To analyze the changes of latent period of pudendal nerve. [results] anal resting pressure in patients with rectal prolapse, The contractile pressure was lower than that of normal subjects (P 0.05), the length of anal canal function was shortened (P 0.05), the initial rectal sensory and defecation thresholds were higher than that of normal controls (P 0.05), and the maximum rectal tolerance threshold did not change significantly. The latent period of pudendal nerve in patients with rectal prolapse was longer than 2.6 ms.Conclusion the resting stool and contractile function of anal canal in patients with rectal prolapse were decreased, the sensitivity of rectal mucosa was decreased, the reaction of submucosal plexus of rectum was decreased, and the latency of pudendal nerve was prolonged.
