Backgrounds Grade I and II haemorrhoids are commonly managed in colorectal practice. Management often involves rubber band ligation. The haemorrhoid energy therapy (HET) device (Medtronic, Minneapolis, MN, USA) has been developed as an alternative to rubber band ligation (RBL). This study is the first to prospectively evaluate the device versus RBL in the management of grade I and II haemorrhoids. Methods A single blind, randomized controlled trial was conducted in the colorectal outpatient department. Patients with symptomatic haemorrhoids suitable for banding were prospectively recruited and randomized. Primary outcome was post procedural pain at 1 h as recorded on a 10‐point Likert scale. Secondary outcomes were efficacy in reduction of haemorrhoidal symptom score at 12 weeks, daily average and maximum pain scores for 14 days and complications arising from the intervention. Results Thirty patients were randomized (14 HET, 16 RBL). There was no significant difference between the two group's pre‐intervention symptom score and haemorrhoidal grade. The mean pain scores at 1 h in the HET group were 1.5 ± 068 (95% confidence interval), and in the RBL group 4.64 ± 1.74 (95% confidence interval) ( P < 0.05). Average (0.7 versus 2.95, P < 0.05) and maximum (1.25 versus 4.4, P < 0.05) pain were lower in the HET group on day one post procedure. At 12 weeks there was no significant difference in the reduction of haemorrhoid symptom scores between the groups (HET 2.27, RBL 1.5 ( P > 0.2)). Conclusion HET causes less pain then RBL, and is at least as effective in treating the symptoms associated with grade I and II haemorrhoids in the outpatient setting.
