大肠正常功能依赖完整的自主神经支配。由于创伤、肿瘤、糖尿病、传染病或神经变性造成1或2支自主神经的损伤,常导致各种肠道运动和分泌功能障碍,最常见的是便秘。乙酰胆碱汗斑试验是一种新的检查自主神经完整性的方法。晚近认为,该方法较常规方法灵敏度高,定量可靠。 The normal function of the large intestine depends on complete autonomic innervation. Damage to one or two autonomic nerves due to trauma, cancer, diabetes, infectious disease, or neurodegeneration often leads to various bowel movements and secretory dysfunctions, most commonly constipation. Acetylcholine stain test is a new method to check the integrity of autonomic nerve. Recently think that the method is more sensitive than conventional methods, quantitative and reliable.
