Summary

Hemorrhoidectomy can be carried out under several modes of anesthesia. In western country hemorrhoidectomy usually be performed under general anesthesia, however there may be the complications resulted from general anesthesia together with associated diseases in advanced age, caudal or spinal anesthesia has been used as an alternative to general anesthesia (GA) for hemorrhoid surgery but they all require a trained anesthetist and have numerous known complications. Since, anesthesiologists are not always available then local anesthesia is an alternative mode of anesthesia that surgeon can safely carry out by their own. Local anesthetic produce a loss of sensation and muscle paralysis in a circumscribed area of body by localized effect on peripheral nerve endings. The local anesthesia is able to provide fully relaxation of the anal canal which is an ideal setting for various anal surgical procedures. The results of hemorrhoid surgery under this mode of anesthesia have been demonstrated in many publications. Local anesthesia is a safe and effective technique while fewer risks and complications compared with general or spinal anesthesia. In Thailand both spinal anesthesia and local perianal block have routinely been used for various kinds of anorectal surgery. However, so far there has no any trial conducting to compare between these two techniques.
