Randomized Controlled Trial Clinical Trial
Effect of transcutaneous electrical nerve stimulation for pain relief on patients undergoing hemorrhoidectomy: prospective, randomized, controlled trial.
Posthemorrhoidectomy pain control remains a challenging problem. Transcutaneous electrical nerve stimulation is known to be effective in the treatment of many diseases. Our aim was to investigate the effect of transcutaneous electrical nerve stimulation on pain relief in patients undergoing hemorrhoidectomy. ⋯ Transcutaneous electrical nerve stimulation is effective for pain relief in patients receiving hemorrhoidectomy. Its efficacy and safety could assist outpatient pain management after hemorrhoidectomy.

Randomized Controlled Trial Clinical Trial
Local injection of bupivacaine after rubber band ligation of hemorrhoids: prospective, randomized study.
The aim of this study was to determine if local injection of bupivacaine after hemorrhoidal banding causes a decrease in pain and in the incidence of associated symptoms. ⋯ Bupivacaine injection may be useful for reducing pain and associated symptoms long enough to tolerate a trip home from the outpatient department but does not show a sustained effect.

Pudendal neuralgia caused by nerve compression may be improved by surgical decompression of the pudendal nerve. This study was undertaken to determine if clinical symptoms, electrophysiological investigations, and the efficacy of preoperative pudendal nerve blocks could be used to predict the efficacy of surgery. ⋯ This preliminary study suggests that complete disappearance of pain for at least two weeks after a nerve block repeated twice before surgery may be the best criterion to predict success. Based on this criterion, surgery would have been performed in four patients in this study, of whom three would have been cured.
