摘　　要：目的了解躯体神经(鞘神经)在齿状线周边分布的情况,探讨痔术后疼痛原因。方法通过对混合痔术后切除的横跨齿状线的痔体做病理切片,以神经染色的方法,了解躯体神经(鞘神经)在齿状线附近分布的情况。同时比较改良混合痔外剥内扎术与传统方法术后疼痛差异。结果约50%肛门神经末梢跨越齿状线,最长可跨越齿状线上2厘米。结论肛门神经末梢跨越齿状线可能是导致传统痔手术后疼痛的重要原因。Objective To investigate the distribution of somatic nerves （nerve sheath） around the dentate line and explain the reasons of postoperative pain of mixed hemorrhoid. Methods A total of 250 histological specimens from mixed hemorrhoid were observed under microscope through using nerve osmium tetroxide staining, and tried to explain whether the distribution of somatic nerves （nerve sheath） around the dentate line was associated with postoperative pain of mixed hemorrhoid. Results About 50% of anal nerve endings distributed across the dentate line, and the farthest ones reached for up to 2 cm beyond the dentate line. Conclusions Near a half of anal nerve endings was beyond dentate line in patients with mixed hemorrhoid, and it may be is the cause of pain after mixed hemorrhoid surgery.
