Histological examination of the lower margin of the internal sphincter has demonstrated an increased amount of fibrous tissue in patients with haemorrhoids compared with controls. This finding may be of relevance to the treatment of haemorrhoids by maximal anal dilatation.
与对照组相比,对患有痔疮的患者内括约肌下缘进行组织学检查发现,其纤维组织量有所增加。这一发现可能与通过最大程度肛门扩张治疗痔疮有关。
