A prospective study as been carried out on fifty patients with haemorrhoids treated by the Lord method who were followed up for at least four years. All patients were interviewed and examined regularly during the observation period. 75% of patients were rendered symptom-free or considerably improved. Apparently the long-term results of this method of treatment can be predicted from the results at eighteen months after operation.
对50例采用洛德法治疗的痔疮患者进行了一项前瞻性研究，对他们进行了至少四年的随访。在观察期内，所有患者均接受定期访谈和检查。75%的患者症状消失或有显著改善。显然，这种治疗方法的长期效果可以根据术后18个月的结果来预测。
