Objectives: To study analgesic efficacy, postoperative voiding problems, patients' satisfaction, and other complications after closed hemorrhoidectomy comparison between local perianal block and spinal anesthesia.
Research design: Randomized controlled trial Setting: Phramongkutklao Hospital Research methodology: A total of 64 subjects (32 males and 32 females) underwent elective hemorrhoidectomy were randomly allocated into two groups. Thirty-two patients were randomly allocated to receive spinal anesthesia (SA group) while 32 patients received local perianal block (LA group). Duration of analgesic effect, pain measurement with visual analogue scale (VAS) at 6 and 24 hours, quantity of analgesic medication administered, postoperative complication, and patient's satisfaction with the anesthetic technique were recorded.

Procedure: Perianal block
0.25% bupivacaine injected at perianal region
Other Name: Marcaine 0.25%
