One hundred patients with non-prolapsing and one hundred with prolapsing haemorrhoids were allocated to receive conventional treatment (CT) by injection sclerotherapy or rubber band ligation, or infrared photocoagulation (IRC). Significantly more patients with nonprolapsing haemorrhoids were symptom free after IRC (81%) than CT (59%) at three months. (Chi2 = 4.4, p = 0.05). There was no significant difference in the outcome at 1 or 4 years. Likewise for prolapsing haemorrhoids, there was no significant difference in the outcome of IRC or CT at 3 months, one or 4 years. However, recurrence of prolapse was more common after IRC (54%) than rubber band ligation (RBL) (27%) at 1 year (Chi2 = 3.46, p less than 0.1). IRC was significantly less painful than CT (p less than 0.001). IRC is a safe, rapid, non-invasive alternative to CT, which is acceptable to the patient and give similar results, though RBL provides more rapid and longer lasting relief from prolapse.
100例非脱垂性痔患者和100例脱垂性痔患者被分配接受传统治疗（CT），即注射硬化疗法、橡皮圈套扎术或红外线凝固疗法（IRC）。在三个月时，接受IRC治疗的非脱垂性痔患者症状消失的比例（81%）显著高于接受CT治疗的患者（59%）。（卡方值=4.4，p=0.05）。在1年或4年时，结果没有显著差异。同样，对于脱垂性痔，在3个月、1年或4年时，IRC或CT的结果没有显著差异。然而，在1年时，IRC治疗后脱垂复发（54%）比橡皮圈套扎术（RBL）（27%）更常见（卡方值=3.46，p<0.1）。IRC的疼痛程度明显低于CT（p<0.001）。IRC是一种安全、快速、非侵入性的替代CT的方法，患者可以接受，且结果相似，不过RBL能更快、更持久地缓解脱垂。
