About this study

Official title: A Randomized Clinical Trial of Closed Hemorrhoidectomy Under Local Perianal Block Versus Spinal Anesthesia

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.

Read the detailed description

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.

    Measured: within 24 hrs

Secondary outcomes (1)
  1. Patients' satisfaction with the anesthetic techniques, postoperative voiding complications, and other complications

    Measured: within 24 hrs

Questions about this trial

What is this clinical trial studying?

A study testing spinal block and Perianal block in people with Postoperative Pain and Complications, run by Phramongkutklao College of Medicine and Hospital.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 22 Jun 2009. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The degree of pain measured by visual analogue scale at 6 and 24 hrs after surgery. (time frame: within 24 hrs). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 22 Jun 2009.
