Treatment of haemorrhoids by transanal haemorrhoidal dearterialization. Experience of several specialized units.

INTRODUCTION Milligan-Morgan and Ferguson haemorrhoidectomy has been the gold standard treatment for symptomatic haemorrhoids for many years. However, escisional techniques are associated with a significant morbidity rate. In recent years, diverse techniques have been described in an attempt to decrease these complications. The guided transanal haemorrhoidal dearterialization THD) doppler is one of these techniques. We report our experience with this new technique. METHODS We performed a prospective study of 475 patients from 5 hospitals from the National Health System, in Spain. The majority of these patients suffered from third grade haemorrhoids (256 [56%]) and underwent THD. We analyse and compare preoperative and postoperative results as well as the homogeneity of the technique between hospitals. RESULTS Spinal anaesthesia was the most elected procedure by the anaesthetist (81.0%). Statistically significant differences were found between pre and postoperative symptoms (P=.03), with an overall improvement after surgery. The average hospitalization was 0.4±0.3 days. The mean number of days of oral analgesics was 8.8±2.7 days. The cumulative complication rate is 16%. CONCLUSION THD is a safe and easily reproducible procedure. Postoperative outcomes demonstrated a low rate of morbidity and recurrence together with early discharge; therefore, a rapid incorporation to daily activities was noted.
