Abstract

Rubber band ligation of hemorrhoids is a common procedure for the realization of coloproctology offices worldwide due to its practicality, low cost and good results achieved with the technique. The biggest drawback is pain, the most common complication of the procedure. The use of topical anesthesia to reduce the pain of the procedure have been described, but most with little or unsatisfactory results. In the present study, we evaluated the efficacy of compound lidocaine cream and prilocaine, applied 30 minutes before ligation in reducing the intensity or duration of pain and the frequency of complications of rubber band ligation of hemorrhoids. In the study, 30 patients were randomized into two groups receiving application of vaseline or anesthesic cream prior to the ligation. Made self-assessment of pain in form with pain scale 0-5, at the time of the procedure and the 6 th, 12 th, 24 th, 48 th and 72 nd minute following. A trend was observed for the reduction of pain during the procedure only in the group that received the anesthesic cream, and duration of pain in the same group, but no statistical significance (p>0.05). There was a statistically significant reduction (p=0.03) in the ocorrence of bladder tenesmus after the procedure.
