Comparison of rubber band ligation and haemorrhoidectomy for second- and third-degree haemorrhoids: a prospective clinical trial. The treatment of second degree haemorrhoids by injection, rubber band ligation, maximal anal dilatation, and haemorrhoidectomy: a prospective clinical trial. Trial of maximal anal dilatation, cryotherapy and elastic band ligation as alternatives to haemorrhoidectomy in the treatment of large prolapsing haemorroids.
One hundred patients with second- or third-degree haemorrhoids were randomly allocated to haemorrhoidectomy (50) or rubber band ligation (50). Forty-two in each group presented with rectal bleeding; haemorrhoidectomy relieved 36 and rubber band ligation relieved 31 of this symptom. All patients had prolapsing haemorrhoids at presentation. One year after treatment 45 haemorrhoidectomy and 43 rubber band ligation patients were assessed. Haemorrhoidectomy relieved 44 of 45 patients and rubber band ligation relieved 34 of 43 (P < 0.05). Haemorrhoidectomy caused pain in all cases, lasting for more than 48 h in 35. Rubber band ligation was painless in 5 and produced pain for more than 48 h in 15. Mean time off work was 32 days for haemorrhoidectomy and 3 days for rubber band ligation (P < 0.001). Rubber band ligation as an outpatient procedure is an effective treatment for second- and third-degree haemorrhoids and should be considered before recourse to surgery. One hundred and twenty patients with confirmed second degree haemorrhoids were randomly allocated to four treatment groups; injection, rubber band ligation, maximal anal dilatation, and haemorrhoidectomy. Each groups consisted of 30 patients. All patients were regularly followed up for at least one year. Assessment at one year showed that haemorrhoidectomy "cured" the haemorrhoids in 29 out of 30 patients. Rubber band ligation relieved 25 out of 30 and maximal anal dilatation 24 out of 30. Injection was the least effective treatment, and relieved 18 of the 30 patients, with a cure rate of 60% only. Haemorrhoidectomy caused pain in all cases, anal stenosis in two, postoperative haemorrhage in two, and the patients required an average hospital stay of 11.5 days and an average of a further 15.5 days off work. Rubber band ligation was painless in 26 patients out of 30, and maximal anal dilatation was painless in 25 our of 30. There were no postoperative complications in the latter two treatment groups. Haemorrhoidectomy is good in "curing" the disease, but the higher possibility of postoperative pain and complications and longer hospital stay would not justify its use in the treatment of second degree haemorrhoids. Both rubber band ligation and maximal anal dilatation are effective and relatively free from complications. Rubber band ligation has the additional advantage of not requiring hospital stay or anaesthesia and is therefore considered to be the most appropriate method of treatment for second degree haemorrhoids. A selected group of 112 patients with prolapsing haemorrhoids which had failed to respond to injections of phenol in oil or which required manual replacement after defecation, were randomly allocated treatment by haemorrhoidectomy, maximal anal dilation, elastic band ligation or cryotherapy. When results were assessed 5 weeks after treatment, haemorrhoidectomy and maximal anal dilatation were equally effective in reducing symptoms, although more physical signs remained after maximal anal dilatation; cryotherapy and elastic band ligation were less effective in both respects. When patients were followed up between 6 months and 5 years haemorrhoidectomy was found to be the most effective method. Patients in the other three groups developed recurrent symptoms requiring haemorrhoidectomy.
The present systematic review confirms the long-term efficacy of EH, at least for grade III haemorrhoids, compared to the less invasive technique of RBL but at the expense of increased pain, higher complications and more time off work. However, despite these disadvantages of EH, patient satisfaction and patient's acceptance of the treatment modalities seems to be similar following both the techniques implying patient's preference for complete long-term cure of symptoms and possibly less concern for minor complications. So, RBL can be adopted as the choice of treatment for grade II haemorrhoids with similar results but with out the side effects of EH while reserving EH for grade III haemorrhoids or recurrence after RBL. More robust study is required to make definitive conclusions.
One additional study was identified from the updated search (Ali 2005). However, after careful review and discussion among the authors, it was decided that this study did not meet the necessary criteria for including in the analysis. Hence, the results and conclusion remains the same.
