采用切断猕猴肛门神经主干的方法，制成实验性内痔模型。术后７年患痔猴死亡，对其肛管组织做光、电镜检查，观察到局部肛管组织中小静脉、毛细血管、小动脉、结缔组织及肌组织均有病变，与人慢性内痔病变有类似性。提示直肠肛管处力的平衡失调在痔的发生中起关键作用，破坏力平衡所致的动物内痔模型可为临床痔的治疗提供筛选途径。 An experimental intrahemorrhoids model was made by cutting off the main body of the rhesus monkey anal nerve. 7 years after operation, hemorrhoids died of hemorrhoids, light and electron microscopy were performed on the anal canal tissues, and the lesions of the small veins, capillaries, arterioles, connective tissues and muscle tissues in the local anal canal tissues were observed. The chronic internal hemorrhoids lesions Similarity. Suggesting that the balance of rectum anal canal imbalance in the occurrence of hemorrhoids play a key role in the balance of destructive internal hemorrhoids animal models for the treatment of clinical hemorrhoids provide a screening approach.
