Transanal haemorrhoidal dearterialization for the treatment of grade III and IV haemorrhoids: a 3-year experience

BackgroundTransanal haemorrhoidal dearterialization (THD) is increasingly perceived as an effective and better tolerated alternative to excisional haemorrhoidectomy. The aim of this study was to evaluate outcomes and the patient experience of THD in an Australian population with grade III or IV haemorrhoids. MethodsA retrospective review of prospectively maintained database on patients who had undergone THD over a 3-year period was performed. Data were collected on demographics, operative data, complications, recurrences and readmissions, postoperative pain and further interventions. Patient perceptions and satisfaction with the procedure were assessed with a telephone survey. ResultsA total of 85 patients with a mean age of 55 (14) years with grade III (85%) or grade IV (15%) haemorrhoids underwent THD. Indications for surgery were predominantly bleeding (87%) and prolapse (41%). Median outpatients follow-up was 42 days and median telephone follow-up was 802 days. Median operating time was 25min (+/- 12). Twenty-four per cent of patients suffered complications, including postoperative bleeding (7%), constipation (7%), local sepsis (6%), anal fissure (5%) and temporary incontinence (2%). Severe postoperative pain occurred in 16% of the patients. The symptom recurrence rate was 19% and reintervention rate was 14%. About 98.8% of patients reported good or excellent overall satisfaction with the procedure. ConclusionTHD is a relatively new technique for the treatment of haemorrhoids, which is increasingly being used as an alternative to excisional haemorrhoidectomy. This study shows that patients' satisfaction with THD is high despite a moderate complication and recurrence rate and significant incidence of postoperative pain.
